Remarque : Si seul le protocole IP est utilisé sur le système où Netport Manager est installé, le serveur d’impression NetportExpress doit utiliser une adresse IP pour communi-quer avec Netport Manager. Imprimez une page d’essai pour savoir si une adresse IP a été définie pour le serveur d’impression. Le cas échéant, définissez cette adresse selon la marche à suivre décrite à la page 15. Configuration du serveur d’impression pour vos NOS. Consultez . . . Configuration de NDS de Novell NetWare ...................................... page 8 Configuration de Bindery de Novell NetWare ................................ page 10 Impression réseau dans l’environnement Microsoft ....................... page 12 Configuration de LAN Manager/LAN Server ................................ page 16 Configuration d’AppleTalk .............................................................. page 18 Configuration d’UNIX .................................................................... page 19 Configuration d’AIX ....................................................................... page 27 Remarque : Vous pouvez configurer chaque port du serveur d’impression NetportExpress pour utilisation de protocoles multiples. 7 Fenêtre principale de Netport Manager Cliquez sur le bouton Properties pour régler les paramètres matériels et les paramètres de nom pour Netport. Cliquez sur le bouton Configure pour configurer le serveur d’impression NetportExpress. Création de disquettes d’installation Vous pouvez créer des disquettes d’installation pour les programmes suivants : • Netport Manager • Port Monitor (pour l’impression Microsoft Network) Les disquettes d’installation ainsi créées vous permettent d’installer ces programmes sur tout système équipé d’une unité de disquette 3 1/2. Pour créer les disquettes, insérer le CD-ROM dans le lecteur. A l’écran qui apparaît, cliquez sur Make Setup Disks. Web Netport Manager S’il n’y a aucune station de travail Windows sur votre réseau pour exécuter Netport Manager, vous pouvez installer votre serveur d’impression NetportExpress à l’aide de l’explorateur Web. Le serveur d’impression comprend un serveur http permettant d’afficher et de modifier les paramètres du serveur d’impression à partir de l’explorateur Web. Dans un tel cas, une adresse IP doit avoir été affectée au serveur d’impression. • Pour savoir si une telle adresse existe pour le serveur, imprimez une page d’essai à l’aide du bouton « diag » du serveur d’impression. • Consultez la rubrique « Définition d’une adresse IP », aux pages 15 et 20 pour savoir comment attribuer une telle adresse au serveur. • Consultez la rubrique « Utilisation de Web Netport Manager » à la page 31 pour savoir comment accéder à ce logiciel. 8 Avec ce mode, le serveur d’impression NetportExpress remplace le programme de serveur d’impression NetWare. Le serveur d’impression NetportExpress interroge la file d’attente du serveur de fichiers NetWare pour savoir si des tâches d’impression s’y trouvent et envoie ensuite chaque tâche directement à l’imprimante. Cette méthode accélère l’impression. Le mode serveur d’impression est recommandé car il assure la meilleure performance en termes d’impression. Pour pouvoir utiliser ce mode, vous devez disposer d’une licence d’utilisation NetWare pour chaque imprimante (y compris les serveurs d’impression multiports). Configuration du serveur d’impression en mode serveur d’impression NDS Remarque : Netport Manager crée les files d’attente ou les serveurs d’impression dont vous avez besoin pour l’installation de NetWare. Il n’est donc pas nécessaire de créer ces objets dans NWADMIN ou PCONSOLE. 1 Ouvrez une session en tant qu’Admin à la station de travail où Netport Manager a été installé. 2 Lancez Netport Manager. 3 Sélectionnez le serveur d’impression dont l’ID de périphérique correspond au numéro du serveur d’impression NetportExpress que vous avez installé. 4 Cliquez sur le bouton Configure. 5 Sélectionnez Novell NDS Print Server. 6 Sélectionnez un contexte pour le serveur d’impression. Le contexte est en quelque sorte le contenant dans lequel l’objet serveur d’impression est créé. 7 Pour chaque imprimante connectée au serveur d’impression, cliquez sur un onglet Port et attribuez-lui une file d’attente existante ou encore ajoutez une nouvelle file. • Pour affecter une file d’attente existante, double-cliquez sur la file pour l’ajouter à la liste des files d’attente affectées (Assigned Queues). • Pour ajouter une nouvelle file, cliquez sur New Queues et créez-en une nouvelle. 8 Cliquez sur OK et quittez Netport Manager. Configuration d’une station de travail aux fins d’impression A chaque station de travail qui utilisera l’imprimante, utilisez la commande capture ou l’utilitaire d’impression de la station de travail pour rediriger l’impression à la file d’attente NetWare que vous avez définie. Pour des instructions complémentaires, consultez la rubrique sur l’aide NetportExpress pour l’impression sous NetWare. Configuration en mode serveur d’impression NDS de Novell NetWare Conseil pour le mode serveur d’impression NDS Pour les paramètres avancés comme LIP (paquets Internet), consultez la rubrique « Gestion du serveur d’impression NetportExpress » à la page 30. 9 Dans ce mode, PSERVER.NLM interroge la file d’attente du serveur de fichiers NetWare pour savoir si des tâches d’impression s’y trouvent et envoie ensuite la tâche d’impression au serveur d’impression, qui achemine les données à l’imprimante. Aucune licence d’utilisateur NetWare n’est nécessaire pour les serveurs d’impression NetportExpress. Ce mode n’est toutefois pas recommandé car il est beaucoup plus lent que le mode serveur d’impression. Configuration du serveur d’impression en mode imprimante distante NDS pour Novell NetWare 1 Ouvrez une session en tant qu’Admin à la station de travail où Netport Manager a été installé. 2 S’il n’existe pas de serveur d’impression, créez-en un à l’aide de NWADMIN ou de PCONSOLE. 3 Lancez Netport Manager. 4 Sélectionnez le serveur d’impression dont l’ID de périphérique correspond au numéro du serveur d’impression NetportExpress que vous avez installé. 5 Cliquez sur le bouton Configure. 6 Sélectionnez Novell NDS Remote Printer. 7 Sélectionnez un contexte pour le serveur d’impression.

Problèmes relatifs au matériel du serveur d’impression Dépannage du serveur d’impression NetportExpress 34 Que signifie le voyant vert 10/100 ? r Ce voyant, situé au bout du périphérique PRO/100, devrait être éteint (OFF) sur les systèmes 10 Mbits/s et allumé (ON) sur les systèmes 100 Mbits/s. Comment faut-il régler les interrupteurs ? r Serveurs d’impression PRO,version pour réseaux en anneau à jeton seulement Vitesse du réseau Interrupteur 1 Interrupteur 2 Détection automatique de la vitesse Vers le haut (Up) Vers le haut (Up) Réglage à 4 Mbits/s Vers le bas (Down) Vers le bas (Down) Réglage à 16 Mbits/s Vers le bas (Down) Vers le haut (Up) r Serveurs d’impression Ethernet PRO et PRO/100 Ne s’applique pas. Les interrupteurs sont réservés pour usage ultérieur. Problèmes d’impression Impression impossible (commencez ici dans la plupart des cas) r La vitesse du port parallèle peut ne pas convenir. La vitesse de ce port doit être identique à celle de l’imprimante (voir le tableau ci-dessous). Vitesse du port parallèle Type d’imprimante utilisant cette vitesse Basse HP LaserJet 3* ou modèles antérieurs, imprimantes à matrice de points et imprimantes à jet d’encre Moyenne Valeur par défaut. HP LaserJet 4* ou l’équivalent et la plupart des autres imprimantes Elevée HP LaserJet 5si* (24 ppm) ou imprimantes plus rapides Logiciel A n’utiliser que si aucune autre vitesse ne convient. Réglage de la vitesse du port : • Sous Netport Manager, cliquez sur le bouton Properties. • Utilisez telnet pour accéder au menu principal telnet et choisissez Port Configuration. • A l’aide de l’explorateur Web, entrez l’adresse IP de votre serveur d’impression NetportExpress et choisissez ensuite Properties. r L’imprimante est éteinte ou n’est pas en ligne. Assurez-vous que l’imprimante fonctionne bien. Imprimez une page d’autovérification pour vous en assurer. r Le serveur d’impression NetportExpress n’est peut-être pas convenablement configuré. Vérifiez l’état (Status) sous Netport Manager. 35 r Le serveur n’est pas en ligne ou ne fonctionne pas. Vérifiez si les voyants du serveur d’impression NetportExpress sont bien allumés. Appuyez sur le bouton diag du périphérique pour imprimer une page d’essai afin de vérifier la configuration. r Le câble d’imprimante est trop long ou endommagé. Assurez-vous que ce câble ne dépasse pas 1,80 m de long. Si vous pensez que le problème se situe au niveau du câble, remplacez celui-ci avec un câble en bon état. Impression impossible sous AppleTalk r Le réseau est peut-être mal configuré. Assurez-vous que le Panneau de configuration est paramétré sur le réseau approprié (LocalTalk*, EtherTalk* ou TokenTalk*, selon le cas). Si EtherTalk est utilisé sur le réseau, assurez-vous qu’il s’agit d’EtherTalk Phase 2. Pour imprimer à l’aide de Phase 1, connectez le Macintosh au réseau à l’aide d’un routeur (Apple Internet Router* ou Liaison Internet Router*, par exemple) assurant le routage entre Phase 1 et Phase 2. r Vérifiez si le serveur d’impression NetportExpress est configuré pour l’impression AppleTalk. Vérifiez la configuration du serveur d’impression. r L’imprimante choisie ne correspond peut-être pas au type d’imprimante (Printer Type) spécifié sous Netport Manager. Vérifiez si le nom est exactement le même, y compris la casse (majuscules et minuscules) et les espaces. Impression impossible sous LAN Manager ou LAN Server r Des files d’attente peuvent avoir été créées sur un système n’utilisant ni LAN Manager, ni LAN Server. Vérifiez l’emplacement de chaque file d’attente. r Les files d’attente peuvent avoir été affectées au mauvais port. Assurez-vous que les files d’attente sont affectées au port LPT1, LPT2 ou LPT3 du système utilisant LAN Manager ou LAN Server. r Il est possible que les files d’attente soient mal configurées. Assurez-vous qu’un seul port LPT logique soit associé à un port LPT physique donné. Les files d’attente ne doivent pas toutes être affectées au port logique LPT1. Impression impossible sous UNIX r La commande tar, utilisée pour extraire les fichiers proinstall, a peut-être été utilisée de façon incorrecte. Consultez le manuel. r Les paramètres d’impression ne conviennent peut-être pas. La plupart des applications utilisent la commande PASSTHRU pour l’impression. Cette commande est utilisée par les langages d’impression PCL et PostScript. N’utilisez la commande TEXT que si vous imprimez un fichier texte UNIX. 36 r Le réseau n’est peut-être pas connecté au serveur d’impression. Utilisez la commande ping à partir d’une station de travail UNIX pour voir s’il existe une connectivité IP avec la tâche TCP/IP du serveur d’impression Netport. r Si vous utilisez proprint sur un hôte SCO, Solaris, UnixWare ou HP-UX, assurez-vous que le chemin d’accès complet vers proprint soit défini. Assurez-vous que le fichier lp_scrpt1 spécifie le chemin d’accès exact et complet vers l’utilitaire proprint. Veillez également à ce que le numéro de tâche soit spécifié. L’avant-dernière ligne du fichier lp_scrpt1 doit se lire comme suit : (commandes de l’interpréteur ...) | usr/intl/hupx/ proprint ‘basename $0’ job=1 exit $ ? r Si vous utilisez proprint, il est possible que le programme ne fonctionne pas. Assurez-vous en en imprimant une tâche à partir de la ligne de commande, sans utiliser le spouleur. r Si vous utilisez lpd sans proprint et l’impression binaire ou des fichiers PostScript, assurez-vous que le nom de file d’attente est le bon. Ce nom doit être LPT1_PASSTHRU pour les fichiers ASCII. Les files d’attente s’allongent, mais rien ne s’imprime r Un autre serveur dessert peut-être la file d’attente. Sélectionnez une autre file d’attente ou remplacez la file d’attente utilisée par l’autre serveur d’impression. r L’imprimante peut être hors ligne ou être réglée pour un type de port invalide (parallèle ou série). Vérifiez l’imprimante et les ports. r Le réseau n’est peut-être pas connecté. Vérifiez la connexion. Pouvez-vous imprimer une page d’essai? Si c’est le cas, vérifiez la connexion réseau entre la station de travail et le serveur d’impression. Vérifiez également la connexion au concentrateur ou au commutateur. r Si la tâche semble s’imprimer, mais que rien ne sort de l’imprimante, c’est peut- être qu’elle a été acheminée à une autre imprimante. r Il est possible que les paramètres du pilote soient erronés. Vous tentez peut-être d’envoyer une tâche PostScript à une imprimante de type autre que PostScript ou encore d’envoyer une tâche non PostScript à une imprimante PostScript. La tâche ne s’imprime pas correctement r Le pilote d’imprimante n’est peut-être pas le bon. Assurez-vous que le pilote qui convient soit utilisé. r Il est parfois nécessaire de régler l’imprimante en mode autodétection de travaux d’impression PostScript. r Une imprimante PostScript tente peut-être d’imprimer une tâche autre que PostScript. Vérifiez la tâche d’impression et l’imprimante. r Si vous copiez un fichier graphique (binaire) vers LPT1, vous utilisez peut-être un paramètre erroné. Le paramètre doit être /b : copy /b lpt1 où est le nom du fichier que vous désirez imprimer. 37 r Novell NetWare seulement. Le paramètre de page de titre peut être erroné. Insérez le paramètre NT (No Tabs ou pas de tabulation) dans la commande CAPTURE. Les caractères ne s’impriment pas correctement r AppleTalk seulement. Si l’imprimante n’imprime pas les polices correctement, vérifiez si le groupe de polices spécifié dans Netport Manager est le groupe approprié pour l’imprimante. Remarque : Ceci ne s’applique que dans le cas des imprimantes n’ayant aucune fonction d’impression bidirectionnelle. L’imprimante série ne fonctionne pas correctement r Les paramètres du port série ne correspondent peut-être pas à votre imprimante. Sous Netport Manager, ouvrez le menu Device Properties et vérifier la vitesse en bauds sous le port série, ainsi que le réglage de la parité, les bits d’arrêt, et ainsi de suite. Assurez-vous que ces réglages correspondent à votre imprimante. (Vous pouvez également effectuer cette vérification en entrant votre adresse IP dans l’explorateur Web pour accéder aux pages Web du serveur d’impression.) r Il est possible que le serveur d’impression NetportExpress ne soit plus sous tension ou qu’il soit débranché. Vérifiez, sur l’imprimante, si le voyant de saut de page ou d’activité est allumé. Réinitialisez l’imprimante pour vider les données non imprimables. Vous devrez peut-être réinitialiser le serveur d’impression NetportExpress. r Le câble est peut-être défectueux. Branchez le câble série à une station de travail et essayez d’imprimer. Si aucun fichier ne s’imprime à partir de cette station de travail, remplacez le câble. L’imprimante insère un espace entre les lignes r Le cas échéant, désactivez la fonction de retour automatique à la ligne. Si vous utilisez Netport Manager, sélectionnez le NetportExpress posant problème et cliquez sur Properties. Dans la fenêtre de paramétrage du port, désactivez la fonction de retour automatique à la ligne. Vous pouvez également utiliser l’explorateur Web ou telnet. Consultez la rubrique Gestion du serveur d’impression NetportExpress à la page 30. Il est impossible d’imprimer alors que l’impression fonctionnait auparavant r Si vous avez changé le nom Netport (Netport Name) ou le nom de partage (Share Name) de votre serveur d’impression NetportExpress après avoir configuré celui-ci, le nouveau nom n’apparaît peut-être plus dans la liste des serveurs d’impression et l’imprimante ne peut donc reconnaître votre serveur. Supprimez les configurations de port et réaffectez les serveurs d’impression et les files d’attente, selon le cas. 38 Problèmes liés à Netport Manager Netport Manager ne peut pas être lancé r Vérifiez la station de travail. Essayez d’exécuter Netport Manager à partir d’une autre station. r La configuration n’est peut-être pas terminée. Si vous venez de configurer ou de réinitialiser le serveur d’impression NetportExpress, attendez quelques secondes avant de cliquer sur l’icône de serveur d’impression dans la liste. Le serveur d’impression NetportExpress est absent ou son nom dans la liste est inexact r Il faut peut-être réinitialiser le serveur d’impression NetportExpress. Débranchez le câble d’alimentation et rebranchez-le. Attendez environ 30 secondes et cliquez sur l’icône de serveur d’impression apparaissant dans la liste des serveurs d’impression. Si le serveur n’est toujours pas affiché, cliquez sur le menu View et ensuite sur Refresh. r Si le voyant d’activité clignote à une fréquence précise, c’est qu’il y a peut-être un problème au niveau du périphérique. Vérifiez la liste au début de la section Dépannage. Si vous pensez que le périphérique est défectueux, branchez le serveur d’impression à un autre branchement réseau pour voir s’il fonctionne à cet autre endroit. r Si vous avez changé le nom de partage (Share Name) ou le nom Netport (Netport Name) de votre serveur d’impression NetportExpress après avoir configuré celui-ci, il n’apparaît peut-être plus dans Netport Manager. Reconfigurez le serveur d’impression en spécifiant le(s) nouveau(x) nom(s). Un message est imprimé au lieu de la tâche r Si un message s’imprime au lieu de la tâche demandée, c’est que les communications bidirectionnelles activées pour l’imprimante ne sont pas prises en charge par cette dernière. Sous Netport Manager, allez à Properties, sélectionnez le port et désélectionnez l’option de communications bidirectionnelles. Le défilement de la liste des serveurs d’impression est lent r Il est possible que le réseau compte un grand nombre de serveurs d’impression. Vous pouvez améliorer la performance de Netport Manager en regroupant les serveurs d’impression. 39 Autres difficultés Impossible de partager les files d’impression dans LAN Manager r LAN Manager seulement. Si vous essayez d’utiliser la commande NET SHARE pour partager une file d’attente qui n’est pas encore affectée à l’imprimante appropriée, le message DOS suivant apparaît : The destination list provided does not match the destination list of the printer queue. Utilisez NET ADMIN pour contrôler et corriger les affectations imprimantes/ files. 1 A l’invite OS/2 plein écran, tapez : NET ADMIN 2 Cliquez sur le menu View et ensuite sur Shared Resources. 3 Dans la fenêtre Shared Resources, sélectionnez . 4 Choisissez l’option Printer et cliquez sur OK. 5 Dans la fenêtre Share a Printer Queue with the Network, sélectionnez la file voulue. Cliquez sur OK. 6 Affichez les informations des ressources partagées (Shared Resource Information) pour connaître les affectations files/imprimantes. Cliquez sur Done. 7 Attribuez aux utilisateurs et aux groupes des droits d’accès à la file d’impression. Sélectionnez l’utilisateur ou le groupe dépourvu de droits d’accès, puis sélectionnez Yes pour « accès autorisé ». Choisissez Permit pour ajouter cet utilisateur ou ce groupe à la liste des droits d’accès affectés (Assigned Permissions). Cliquez sur OK. 8 Quittez NET ADMIN. Oubli du mot de passe r Effectuez une mise à jour sérielle pour supprimer le mot de passe existant. Si le modèle de serveur d’impression NetportExpress ne comporte pas de port série, contactez le service de support clientèle Intel. 40 Limites de la garantie Intel garantit au propriétaire initial que le produit fourni dans cet emballage est exempt de vice de fabrication pièces et main-d’oeuvre pendant une période de trois (3) ans à compter de : (i) la date d’acquisition sous réserve d’enregistrement en renvoyant la carte d’enregistrement accompagnée d’une copie du justificatif d’achat; de (ii) la date de fabrication; ou de (iii) la date d’enregistrement effectué par voie électronique à condition que cet enregistrement intervienne dans un délai de 30 jours suivant l’achat.

Within this temperature range, a component is expected to meet its specified performance. Operation outside the functional temperature range can degrade system performance, cause logic errors or cause component and/or system damage. Temperatures exceeding the maximum operating limit of a component may result in irreversible changes in the operating characteristics of this component. In a system environment, the processor temperature is a function of both system and component thermal characteristics. The system level thermal constraints consist of the local ambient air temperature and airflow over the processor as well as the physical constraints at and above the processor. The processor temperature depends in particular on the component power dissipation, the processor package thermal characteristics, and the processor thermal solution. All of these parameters are affected by the continued push of technology to increase processor performance levels and packaging density (more transistors). As operating frequencies increase and packaging size decreases, the power density increases while the thermal solution space and airflow typically become more constrained or remains the same within the system. The result is an increased importance on system design to ensure that thermal design requirements are met for each component, including the processor, in the system. 1.1.2 Document Goals Depending on the type of system and the chassis characteristics, new system and component designs may be required to provide adequate cooling for the processor.

Refer to the datasheet for detailed mechanical specifications. The processor connects to the motherboard through a land grid array (LGA) surface mount socket. The socket contains 775 contacts arrayed about a cavity in the center of the socket with solder balls for surface mounting to the motherboard. The socket is named LGA775 socket. A description of the socket is in the LGA775 Socket Mechanical Design Guide. The package includes an integrated heat spreader (IHS) that is shown in Figure 2-1 for illustration only. Refer to the processor datasheet for further information. In case of conflict, the package dimensions in the processor datasheet supersedes dimensions provided in this document. Figure 2-1. Package IHS Load Areas Top Surface of IHS to install a heatsink IHS Step to interface w ith LGA775 Socket Load Plate Substrate Top Surface of IHS to install a heatsink IHS Step to interface w ith LGA775 Socket Load Plate Substrate Processor Thermal/Mechanical Information 16 Thermal and Mechanical Design Guidelines The primary function of the IHS is to transfer the non-uniform heat distribution from the die to the top of the IHS, out of which the heat flux is more uniform and spread over a larger surface area (not the entire IHS area). This allows more efficient heat transfer out of the package to an attached cooling device. The top surface of the IHS is designed to be the interface for contacting a heatsink. The IHS also features a step that interfaces with the LGA775 socket load plate, as described in LGA775 Socket Mechanical Design Guide. The load from the load plate is distributed across two sides of the package onto a step on each side of the IHS. It is then distributed by the package across all of the contacts. When correctly actuated, the top surface of the IHS is above the load plate allowing proper installation of a heatsink on the top surface of the IHS. After actuation of the socket load plate, the seating plane of the package is flush with the seating plane of the socket. Package movement during socket actuation is along the Z direction (perpendicular to substrate) only. Refer to the LGA775 Socket Mechanical Design Guide for further information about the LGA775 socket. The processor package has mechanical load limits that are specified in the processor datasheet. The specified maximum static and dynamic load limits should not be exceeded during their respective stress conditions. These include heatsink installation, removal, mechanical stress testing, and standard shipping conditions. • When a compressive static load is necessary to ensure thermal performance of the thermal interface material between the heatsink base and the IHS, it should not exceed the corresponding specification given in the processor datasheet. • When a compressive static load is necessary to ensure mechanical performance, it should remain in the minimum/maximum range specified in the processor datasheet • The heatsink mass can also generate additional dynamic compressive load to the package during a mechanical shock event. Amplification factors due to the impact force during shock must be taken into account in dynamic load calculations. The total combination of dynamic and static compressive load should not exceed the processor datasheet compressive dynamic load specification during a vertical shock. For example, with a 0.550 kg [1.2 lb] heatsink, an acceleration of 50G during an 11 ms trapezoidal shock with an amplification factor of 2 results in approximately a 539 N [117 lbf] dynamic load on the processor package. If a 178 N [40 lbf] static load is also applied on the heatsink for thermal performance of the thermal interface material the processor package could see up to a 717 N [156 lbf]. The calculation for the thermal solution of interest should be compared to the processor datasheet specification. No portion of the substrate should be used as a load- bearing surface. Finally, the processor datasheet provides package handling guidelines in terms of maximum recommended shear, tensile and torque loads for the processor IHS relative to a fixed substrate. These recommendations should be followed in particular for heatsink removal operations. Processor Thermal/Mechanical Information Thermal and Mechanical Design Guidelines 17 2.1.2 Heatsink Attach 2.1.2.1 General Guidelines There are no features on the LGA775 socket to directly attach a heatsink: a mechanism must be designed to attach the heatsink directly to the motherboard. In addition to holding the heatsink in place on top of the IHS, this mechanism plays a significant role in the robustness of the system in which it is implemented, in particular: • Ensuring thermal performance of the thermal interface material (TIM) applied between the IHS and the heatsink. TIMs based on phase change materials are very sensitive to applied pressure: the higher the pressure, the better the initial performance. TIMs such as thermal greases are not as sensitive to applied pressure. Designs should consider a possible decrease in applied pressure over time due to potential structural relaxation in retention components. • Ensuring system electrical, thermal, and structural integrity under shock and vibration events. The mechanical requirements of the heatsink attach mechanism depend on the mass of the heatsink and the level of shock and vibration that the system must support. The overall structural design of the motherboard and the system have to be considered when designing the heatsink attach mechanism. Their design should provide a means for protecting LGA775 socket solder joints. One of the strategies for mechanical protection of the socket is to use a preload and high stiffness clip. This strategy is implemented by the reference design and described in Section 6.7. Note: Package pull-out during mechanical shock and vibration is constrained by the LGA775 socket load plate (refer to the LGA775 Socket Mechanical Design Guide for further information). 2.1.2.2 Heatsink Clip Load Requirement The attach mechanism for the heatsink developed to support the processor should create a static preload on the package between 18 lbf and 70 lbf throughout the life of the product for designs compliant with the reference design assumptions: • 72 mm x 72 mm mounting hole span for ATX (refer to Figure 7-47). • TMA preload vs. stiffness for BTX within the limits shown on Figure 5-6. • And no board stiffening device (backing plate, chassis attach, etc.). The minimum load is required to protect against fatigue failure of socket solder joint in temperature cycling. It is important to take into account potential load degradation from creep over time when designing the clip and fastener to the required minimum load. This means that, depending on clip stiffness, the initial preload at beginning of life of the product may be significantly higher than the minimum preload that must be met throughout the life of the product. For additional guidelines on mechanical design, in particular on designs departing from the reference design assumptions refer to Appendix A. For clip load metrology guidelines, refer to Appendix B. Processor Thermal/Mechanical Information 18 Thermal and Mechanical Design Guidelines 2.1.2.3 Additional Guidelines In addition to the general guidelines given above, the heatsink attach mechanism for the processor should be designed to the following guidelines: • Holds the heatsink in place under mechanical shock and vibration events and applies force to the heatsink base to maintain desired pressure on the thermal interface material. Note that the load applied by the heatsink attach mechanism must comply with the package specifications described in the processor datasheet. One of the key design parameters is the height of the top surface of the processor IHS above the motherboard. The IHS height from the top of board is expected to vary from 7.517 mm to 8.167 mm. This data is provided for information only, and should be derived from: ⎯ The height of the socket seating plane above the motherboard after reflow, given in the LGA775 Socket Mechanical Design Guide with its tolerances. ⎯ The height of the package, from the package seating plane to the top of the IHS, and accounting for its nominal variation and tolerances that are given in the corresponding processor datasheet. • Engages easily, and if possible, without the use of special tools. In general, the heatsink is assumed to be installed after the motherboard has been installed into the chassis. • Minimizes contact with the motherboard surface during installation and actuation to avoid scratching the motherboard. 2.2 Thermal Requirements Refer to the datasheet for the processor thermal specifications. The majority of processor power is dissipated through the IHS. There are no additional components, e.g., BSRAMs, which generate heat on this package. The amount of power that can be dissipated as heat through the processor package substrate and into the socket is usually minimal. The thermal limits for the processor are the Thermal Profile and TCONTROL. The Thermal Profile defines the maximum case temperature as a function of power being dissipated. TCONTROL is a specification used in conjunction with the temperature reported by the digital thermal sensor and a fan speed control method. Designing to these specifications allows optimization of thermal designs for processor performance and acoustic noise reduction. 2.2.1 Processor Case Temperature For the processor, the case temperature is defined as the temperature measured at the geometric center of the package on the surface of the IHS. For illustration, Figure 2-2 shows the measurement location for a 37.5 mm x 37.5 mm [1.474 in x 1.474 in] 775-Land LGA processor package with a 28.7 mm x 28.7 mm [1.13 in x 1.13 in] IHS top surface. Techniques for measuring the case temperature are detailed in Section 3.4. Note: In case of conflict, the package dimensions in the processor datasheet supersedes dimensions provided in this document. Processor Thermal/Mechanical Information Thermal and Mechanical Design Guidelines 19 Figure 2-2. Processor Case Temperature Measurement Location 37.5 mm Measure TC at this point (geometric center of the package) 37.5 mm 37.5 mm Measure TC at this point (geometric center of the package) 37.5 mm 2.2.2 Thermal Profile The Thermal Profile defines the maximum case temperature as a function of processor power dissipation. The TDP and Maximum Case Temperature are defined as the maximum values of the thermal profile. By design the thermal solutions must meet the thermal profile for all system operating conditions and processor power levels. Refer to the processor datasheet for further information. While the thermal profile provides flexibility for ATX /BTX thermal design based on its intended target thermal environment, thermal solutions that are intended to function in a multitude of systems and environments need to be designed for the worst-case thermal environment. The majority of ATX /BTX platforms are targeted to function in an environment that will have up to a 35 °C ambient temperature external to the system. Note: For ATX platforms, an active air-cooled design, assumed be used in ATX Chassis, with a fan installed at the top of the heatsink equivalent to the reference design (see Chapter 6) should be designed to manage the processor TDP at an inlet temperature of 35 °C + 5 °C = 40 °C. For BTX platforms, a front-to-back cooling design equivalent to Intel BTX TMA Type II reference design (see the Chapter 5) should be designed to manage the processor TDP at an inlet temperature of 35 °C + 0.5 °C = 35.5 °C. The slope of the thermal profile was established assuming a generational improvement in thermal solution performance of the reference design. For an example of Intel® Core™2 Duo processor with 4 MB cache at Tc-max of 60.1 °C in ATX platform, its improvement is about 16% over the Intel reference design (D60188- 001). This performance is expressed as the slope on the thermal profile and can be thought of as the thermal resistance of the heatsink attached to the processor, ΨCA (Refer to Processor Thermal/Mechanical Information 20 Thermal and Mechanical Design Guidelines Section 3.1). The intercept on the thermal profile assumes a maximum ambient operating condition that is consistent with the available chassis solutions. To determine compliance to the thermal profile, a measurement of the actual processor power dissipation is required. The measured power is plotted on the Thermal Profile to determine the maximum case temperature. Using the example in Figure 2-3 for the Intel® Core™2 Duo processor with 4 MB cache at Tc-max of 60.1 °C dissipating 50 W, the maximum case temperature is 56.2 °C. See the datasheet for the thermal profile. Figure 2-3. Example Thermal Profile 2.2.3 TCONTROL TCONTROL defines the maximum operating temperature for the digital thermal sensor when the thermal solution fan speed is being controlled by the digital thermal sensor. The TCONTROL parameter defines a very specific processor operating region where fan speed can be reduced. This allows the system integrator a method to reduce the acoustic noise of the processor cooling solution, while maintaining compliance to the processor thermal specification. Note: The TCONTROL value for the processor is relative to the Thermal Control Circuit (TCC) activation set point which will be seen as 0 via the digital thermal sensor. As a result the TCONTROL value will always be a negative number. See Chapter 4 for the discussion the thermal management logic and features and Chapter 7 on Intel® Quiet System Technology (Intel® QST). The value of TCONTROL is driven by a number of factors. One of the most significant of these is the processor idle power. As a result a processor with a high (closer to 0 ) Processor Thermal/Mechanical Information Thermal and Mechanical Design Guidelines 21 TCONTROL will dissipate more power than a part with lower value (farther from 0, e.g., more negative number) of TCONTROL when running the same application. This is achieved in part by using the ΨCA vs. RPM and RPM vs. Acoustics (dBA) performance curves from the Intel enabled thermal solution. A thermal solution designed to meet the thermal profile would be expected to provide similar acoustic performance of different parts with potentially different TCONTROL values. The value for TCONTROL is calculated by the system BIOS based on values read from a factory configured processor register. The result can be used to program a fan speed control component. See the appropriate processor datasheet for further details on reading the register and calculating TCONTROL. See Chapter 7, Intel® Quiet System Technology (Intel® QST), for details on implementing a design using TCONTROL and the Thermal Profile. 2.3 Heatsink Design Considerations To remove the heat from the processor, three basic parameters should be considered: • The area of the surface on which the heat transfer takes place. Without any enhancements, this is the surface of the processor package IHS. One method used to improve thermal performance is by attaching a heatsink to the IHS. A heatsink can increase the effective heat transfer surface area by conducting heat out of the IHS and into the surrounding air through fins attached to the heatsink base. • The conduction path from the heat source to the heatsink fins. Providing a direct conduction path from the heat source to the heatsink fins and selecting materials with higher thermal conductivity typically improves heatsink performance. The length, thickness, and conductivity of the conduction path from the heat source to the fins directly impact the thermal performance of the heatsink. In particular, the quality of the contact between the package IHS and the heatsink base has a higher impact on the overall thermal solution performance as processor cooling requirements become stricter. Thermal interface material (TIM) is used to fill in the gap between the IHS and the bottom surface of the heatsink, and thereby improve the overall performance of the stack-up (IHS-TIMHeatsink). With extremely poor heatsink interface flatness or roughness, TIM may not adequately fill the gap. The TIM thermal performance depends on its thermal conductivity as well as the pressure applied to it. Refer to Section 2.3.4 and Appendix C for further information on TIM and on bond line management between the IHS and the heatsink base. • The heat transfer conditions on the surface on which heat transfer takes place. Convective heat transfer occurs between the airflow and the surface exposed to the flow. It is characterized by the local ambient temperature of the air, TA, and the local air velocity over the surface. The higher the air velocity over the surface, and the cooler the air, the more efficient is the resulting cooling. The nature of the airflow can also enhance heat transfer via convection. Turbulent flow can provide improvement over laminar flow. In the case of a heatsink, the surface exposed to the flow includes in particular the fin faces and the heatsink base. Active heatsinks typically incorporate a fan that helps manage the airflow through the heatsink. Processor Thermal/Mechanical Information 22 Thermal and Mechanical Design Guidelines Passive heatsink solutions require in-depth knowledge of the airflow in the chassis. Typically, passive heatsinks see lower air speed. These heatsinks are therefore typically larger (and heavier) than active heatsinks due to the increase in fin surface required to meet a required performance. As the heatsink fin density (the number of fins in a given cross-section) increases, the resistance to the airflow increases: it is more likely that the air travels around the heatsink instead of through it, unless air bypass is carefully managed. Using air-ducting techniques to manage bypass area can be an effective method for controlling airflow through the heatsink. 2.3.1 Heatsink Size The size of the heatsink is dictated by height restrictions for installation in a system and by the real estate available on the motherboard and other considerations for component height and placement in the area potentially impacted by the processor heatsink. The height of the heatsink must comply with the requirements and recommendations published for the motherboard form factor of interest. Designing a heatsink to the recommendations may preclude using it in system adhering strictly to the form factor requirements, while still in compliance with the form factor documentation. For the ATX/microATX form factor, it is recommended to use: • The ATX motherboard keep-out footprint definition and height restrictions for enabling components, defined for the platforms designed with the LGA775 socket in Appendix H of this design guide. • The motherboard primary side height constraints defined in the ATX Specification V2.1 and the microATX Motherboard Interface Specification V1.1 found at http://www.formfactors.org/. The resulting space available above the motherboard is generally not entirely available for the heatsink. The target height of the heatsink must take into account airflow considerations (for fan performance for example) as well as other design considerations (air duct, etc.). For BTX form factor, it is recommended to use: • The BTX motherboard keep-out footprint definitions and height restrictions for enabling components for platforms designed with the LGA77 socket in Appendix H of this design guide. • An overview of other BTX system considerations for thermal solutions can be obtained in the latest version of the Balanced Technology Extended (BTX) System Design Guide found at http://www.formfactors.org/. 2.3.2 Heatsink Mass With the need to push air cooling to better performance, heatsink solutions tend to grow larger (increase in fin surface) resulting in increased mass. The insertion of highly thermally conductive materials like copper to increase heatsink thermal conduction performance results in even heavier solutions. As mentioned in Section 2.1, the heatsink mass must take into consideration the package and socket load limits, the heatsink attach mechanical capabilities, and the mechanical shock and vibration profile targets. Beyond a certain heatsink mass, the cost of developing and implementing a heatsink attach mechanism that can ensure the system integrity under the mechanical shock and vibration profile targets may become prohibitive. Processor Thermal/Mechanical Information Thermal and Mechanical Design Guidelines 23 The recommended maximum heatsink mass for the ATX thermal solution is 550g. This mass includes the fan and the heatsink only. The attach mechanism (clip, fasteners, etc.) are not included. The mass limit for BTX heatsinks that use Intel reference design structural ingredients is 900 grams. The BTX structural reference component strategy and design is reviewed in depth in the latest version of the Balanced Technology Extended (BTX) System Design Guide. Note: The 550g mass limit for ATX solutions is based on the capabilities of the reference design components that retain the heatsink to the board and apply the necessary preload. Any reuse of the clip and fastener in derivative designs should not exceed 550g. ATX Designs that have a mass of greater than 550g should analyze the preload as discussed in Appendix A and retention limits of the fastener. Note: The chipset components on the board are affected by processor heatsink mass. Exceeding these limits may require the evaluation of the chipset for shock and vibration. 2.3.3 Package IHS Flatness The package IHS flatness for the product is specified in the datasheet and can be used as a baseline to predict heatsink performance during the design phase. Intel recommends testing and validating heatsink performance in full mechanical enabling configuration to capture any impact of IHS flatness change due to combined socket and heatsink loading. While socket loading alone may increase the IHS warpage, the heatsink preload redistributes the load on the package and improves the resulting IHS flatness in the enabled state. 2.3.4 Thermal Interface Material Thermal interface material application between the processor IHS and the heatsink base is generally required to improve thermal conduction from the IHS to the heatsink. Many thermal interface materials can be pre-applied to the heatsink base prior to shipment from the heatsink supplier and allow direct heatsink attach, without the need for a separate thermal interface material dispense or attach process in the final assembly factory. All thermal interface materials should be sized and positioned on the heatsink base in a way that ensures the entire processor IHS area is covered. It is important to compensate for heatsink-to-processor attach positional alignment when selecting the proper thermal interface material size. When pre-applied material is used, it is recommended to have a protective application tape over it. This tape must be removed prior to heatsink installation. Processor Thermal/Mechanical Information 24 Thermal and Mechanical Design Guidelines 2.4 System Thermal Solution Considerations 2.4.1 Chassis Thermal Design Capabilities The Intel reference thermal solutions and Intel Boxed Processor thermal solutions assume that the chassis delivers a maximum TA at the inlet of the processor fan heatsink. The following tables show the TA requirements for the reference solutions and Intel Boxed Processor thermal solutions. Table 2-1. Heatsink Inlet Temperature of Intel Reference Thermal Solutions ATX D60188- 001 ATX E18764-001 BTX Type II Heatsink Inlet Temperature 40 °C 40 °C 35.5 °C NOTE: 1. Intel reference designs (D60188-001 and E18764-001) are assumed be used in the chassis where expected the temperature rise is 5 °C. Table 2-2. Heatsink Inlet Temperature of Intel Boxed Processor Thermal Solutions Boxed Processor for Intel® Core™2 Duo Processor E6000 and E4000 Series, Intel® Pentium® Dual Core Processor E2000 Series, and Intel® Celeron® DualCore Processor E1000 Series Heatsink Inlet Temperature 40 °C NOTE: 1. Boxed Processor thermal solutions for ATX assume the use of the thermally advantaged chassis (refer to Thermally Advantaged Chassis version 1.1 for Thermally Advantaged Chassis thermal and mechanical requirements). 2.4.2 Improving Chassis Thermal Performance The heat generated by components within the chassis must be removed to provide an adequate operating environment for both the processor and other system components. Moving air through the chassis brings in air from the external ambient environment and transports the heat generated by the processor and other system components out of the system. The number, size and relative position of fans and vents determine the chassis thermal performance, and the resulting ambient temperature around the processor. The size and type (passive or active) of the thermal solution and the amount of system airflow can be traded off against each other to meet specific system design constraints. Additional constraints are board layout, spacing, component placement, acoustic requirements and structural considerations that limit the thermal solution size. For more information, refer to the Performance ATX Desktop System Thermal Design Suggestions or Performance microATX Desktop System Thermal Design Suggestions or Balanced Technology Extended (BTX) System Design Guide documents available on the http://www.formfactors.org/ web site. Processor Thermal/Mechanical Information Thermal and Mechanical Design Guidelines 25 In addition to passive heatsinks, fan heatsinks and system fans are other solutions that exist for cooling integrated circuit devices. For example, ducted blowers, heat pipes and liquid cooling are all capable of dissipating additional heat. Due to their varying attributes, each of these solutions may be appropriate for a particular system implementation. To develop a reliable, cost-effective thermal solution, thermal characterization and simulation should be carried out at the entire system level, accounting for the thermal requirements of each component. In addition, acoustic noise constraints may limit the size, number, placement, and types of fans that can be used in a particular design. To ease the burden on thermal solutions, the Thermal Monitor feature and associated logic have been integrated into the silicon of the processor. By taking advantage of the Thermal Monitor feature, system designers may reduce thermal solution cost by designing to TDP instead of maximum power. Thermal Monitor attempts to protect the processor during sustained workload above TDP. Implementation options and recommendations are described in Chapter 4. 2.4.3 Summary In summary, considerations in heatsink design include: • The local ambient temperature TA at the heatsink, which is a function of chassis design. • The thermal design power (TDP) of the processor, and the corresponding maximum TC as calculated from the thermal profile. These parameters are usually combined in a single lump cooling performance parameter, ΨCA (case to air thermal characterization parameter). More information on the definition and the use of ΨCA is given Sections 3.1. • Heatsink interface to IHS surface characteristics, including flatness and roughness. • The performance of the thermal interface material used between the heatsink and the IHS. • The required heatsink clip static load, between 18 lbf to 70 lbf throughout the life of the product (Refer to Section 2.1.2.2 for further information). • Surface area of the heatsink. • Heatsink material and technology. • Volume of airflow over the heatsink surface area. • Development of airflow entering and within the heatsink area. • Physical volumetric constraints placed by the system 2.5 System Integration Considerations Manufacturing with Intel® Components using 775–Land LGA Package and LGA775 Socket documentation provides Best Known Methods for all aspects LGA775 socket based platforms and systems manufacturing.

Processor Thermal/Mechanical Information 26 Thermal and Mechanical Design Guidelines § Thermal Metrology Thermal and Mechanical Design Guidelines 27 3 Thermal Metrology This chapter discusses guidelines for testing thermal solutions, including measuring processor temperatures. In all cases, the thermal engineer must measure power dissipation and temperature to validate a thermal solution. To define the performance of a thermal solution the “thermal characterization parameter”, Ψ (“psi”) will be used. 3.1 Characterizing Cooling Performance Requirements The idea of a “thermal characterization parameter”, Ψ (“psi”), is a convenient way to characterize the performance needed for the thermal solution and to compare thermal solutions in identical situations (same heat source and local ambient conditions). The thermal characterization parameter is calculated using total package power. Note: Heat transfer is a three-dimensional phenomenon that can rarely be accurately and easily modeled by a single resistance parameter like Ψ. The case-to-local ambient thermal characterization parameter value (ΨCA) is used as a measure of the thermal performance of the overall thermal solution that is attached to the processor package. It is defined by the following equation, and measured in units of °C/W: ΨCA = (TC – TA) / PD (Equation 1) Where: ΨCA = Case-to-local ambient thermal characterization parameter (°C/W) TC = Processor case temperature (°C) TA = Local ambient temperature in chassis at processor (°C) PD = Processor total power dissipation (W) (assumes all power dissipates through the IHS) The case-to-local ambient thermal characterization parameter of the processor, ΨCA, is comprised of ΨCS, the thermal interface material thermal characterization parameter, and of ΨSA, the sink-to-local ambient thermal characterization parameter: ΨCA = ΨCS + ΨSA (Equation 2) Where: ΨCS = Thermal characterization parameter of the thermal interface material (°C/W) ΨSA = Thermal characterization parameter from heatsink-to-local ambient (°C/W) Thermal Metrology 28 Thermal and Mechanical Design Guidelines ΨCS is strongly dependent on the thermal conductivity and thickness of the TIM between the heatsink and IHS. ΨSA is a measure of the thermal characterization parameter from the bottom of the heatsink to the local ambient air. ΨSA is dependent on the heatsink material, thermal conductivity, and geometry. It is also strongly dependent on the air velocity through the fins of the heatsink. Figure 3-1 illustrates the combination of the different thermal characterization parameters. Figure 3-1. Processor Thermal Characterization Parameter Relationships TIM TS TA ΨCA LGA775 Socket Processor IHS System Board TC Heatsink TIM TS TA ΨCA LGA775 Socket Processor IHS System Board TC Heatsink 3.1.1 Example The cooling performance, ΨCA, is then defined using the principle of thermal characterization parameter described above: • The case temperature TC-MAX and thermal design power TDP given in the processor datasheet. • Define a target local ambient temperature at the processor, TA. Since the processor thermal profile applies to all processor frequencies, it is important to identify the worst case (lowest ΨCA) for a targeted chassis characterized by TA to establish a design strategy. The following provides an illustration of how one might determine the appropriate performance targets. The example power and temperature numbers used here are not related to any specific Intel processor thermal specifications, and are for illustrative purposes only. Thermal Metrology Thermal and Mechanical Design Guidelines 29 Assume the TDP, as listed in the datasheet, is 100 W and the maximum case temperature from the thermal profile for 100 W is 67 °C. Assume as well that the system airflow has been designed such that the local ambient temperature is 38 °C. Then the following could be calculated using equation 1 (shown on previous page): ΨCA = (TC,- TA) / TDP = (67 – 38) / 100 = 0.29 °C/W To determine the required heatsink performance, a heatsink solution provider would need to determine ΨCS performance for the selected TIM and mechanical load configuration. If the heatsink solution were designed to work with a TIM material performing at ΨCS ≤ 0.10 °C/W, solving for equation 2 from above, the performance of the heatsink would be: ΨSA = ΨCA − ΨCS = 0.29 − 0.10 = 0.19 °C/W 3.2 Processor Thermal Solution Performance Assessment Thermal performance of a heatsink should be assessed using a thermal test vehicle (TTV) provided by Intel. The TTV is a stable heat source that the user can make accurate power measurement, whereas processors can introduce additional factors that can impact test results. In particular, the power level from actual processors varies significantly, even when running the maximum power application provided by Intel, due to variances in the manufacturing process. The TTV provides consistent power and power density for thermal solution characterization and results can be easily translated to real processor performance. Accurate measurement of the power dissipated by an actual processor is beyond the scope of this document. Once the thermal solution is designed and validated with the TTV, it is strongly recommended to verify functionality of the thermal solution on real processors and on fully integrated systems. The Intel maximum power application enables steady power dissipation on a processor to assist in this testing. This maximum power application is provided by Intel. 3.3 Local Ambient Temperature Measurement Guidelines The local ambient temperature TA is the temperature of the ambient air surrounding the processor. For a passive heatsink, TA is defined as the heatsink approach air temperature; for an actively cooled heatsink, it is the temperature of inlet air to the active cooling fan. It is worthwhile to determine the local ambient temperature in the chassis around the processor to understand the effect it may have on the case temperature. TA is best measured by averaging temperature measurements at multiple locations in the heatsink inlet airflow. This method helps reduce error and eliminate minor spatial variations in temperature. The following guidelines are meant to enable accurate determination of the localized air temperature around the processor during system thermal testing. Thermal Metrology 30 Thermal and Mechanical Design Guidelines For active heatsinks, it is important to avoid taking measurement in the dead flow zone that usually develops above the fan hub and hub spokes. Measurements should be taken at four different locations uniformly placed at the center of the annulus formed by the fan hub and the fan housing to evaluate the uniformity of the air temperature at the fan inlet. The thermocouples should be placed approximately 3 mm to 8 mm [0.1 to 0.3 in] above the fan hub vertically and halfway between the fan hub and the fan housing horizontally as shown in the ATX heatsink in Figure 3-2 (avoiding the hub spokes). Using an open bench to characterize an active heatsink can be useful, and usually ensures more uniform temperatures at the fan inlet. However, additional tests that include a solid barrier above the test motherboard surface can help evaluate the potential impact of the chassis. This barrier is typically clear Plexiglas*, extending at least 100 mm [4 in] in all directions beyond the edge of the thermal solution. Typical distance from the motherboard to the barrier is 81 mm [3.2 in]. For even more realistic airflow, the motherboard should be populated with significant elements like memory cards, graphic card, and chipset heatsink. If a barrier is used, the thermocouple can be taped directly to the barrier with a clear tape at the horizontal location as previously described, half way between the fan hub and the fan housing. If a variable speed fan is used, it may be useful to add a thermocouple taped to the barrier above the location of the temperature sensor used by the fan to check its speed setting against air temperature. When measuring TA in a chassis with a live motherboard, add-in cards, and other system components, it is likely that the TA measurements will reveal a highly non-uniform temperature distribution across the inlet fan section. For passive heatsinks, thermocouples should be placed approximately 13 mm to 25 mm [0.5 to 1.0 in] away from processor and heatsink as shown in Figure 3-3. The thermocouples should be placed approximately 51 mm [2.0 in] above the baseboard. This placement guideline is meant to minimize the effect of localized hot spots from baseboard components. Note: Testing an active heatsink with a variable speed fan can be done in a thermal chamber to capture the worst-case thermal environment scenarios. Otherwise, when doing a bench top test at room temperature, the fan regulation prevents the heatsink from operating at its maximum capability. To characterize the heatsink capability in the worst-case environment in these conditions, it is then necessary to disable the fan regulation and power the fan directly, based on guidance from the fan supplier. Thermal Metrology Thermal and Mechanical Design Guidelines 31 Figure 3-2. Locations for Measuring Local Ambient Temperature, Active ATX Heatsink Note: Drawing Not to Scale Figure 3-3. Locations for Measuring Local Ambient Temperature, Passive Heatsink Note: Drawing Not to Scale Thermal Metrology 32 Thermal and Mechanical Design Guidelines 3.4 Processor Case Temperature Measurement Guidelines To ensure functionality and reliability, the processor is specified for proper operation when TC is maintained at or below the thermal profile as listed in the datasheet. The measurement location for TC is the geometric center of the IHS. Figure 2-2 shows the location for TC measurement. Special care is required when measuring TC to ensure an accurate temperature measurement. Thermocouples are often used to measure TC. Before any temperature measurements are made, the thermocouples must be calibrated, and the complete measurement system must be routinely checked against known standards. When measuring the temperature of a surface that is at a different temperature from the surrounding local ambient air, errors could be introduced in the measurements. The measurement errors could be caused by poor thermal contact between the junction of the thermocouple and the surface of the integrated heat spreader, heat loss by radiation, convection, by conduction through thermocouple leads, or by contact between the thermocouple cement and the heatsink base. Appendix D defines a reference procedure for attaching a thermocouple to the IHS of a 775-Land LGA processor package for TC measurement. This procedure takes into account the specific features of the 775-Land LGA package and of the LGA775 socket for which it is intended. § Thermal Management Logic and Thermal Monitor Feature Thermal and Mechanical Design Guidelines 33 4 Thermal Management Logic and Thermal Monitor Feature 4.1 Processor Power Dissipation An increase in processor operating frequency not only increases system performance, but also increases the processor power dissipation. The relationship between frequency and power is generalized in the following equation: P = CV2 F (where P = power, C = capacitance, V = voltage, F = frequency). From this equation, it is evident that power increases linearly with frequency and with the square of voltage. In the absence of power saving technologies, ever increasing frequencies will result in processors with power dissipations in the hundreds of watts. Fortunately, there are numerous ways to reduce the power consumption of a processor, and Intel is aggressively pursuing low power design techniques. For example, decreasing the operating voltage, reducing unnecessary transistor activity, and using more power efficient circuits can significantly reduce processor power consumption. An on-die thermal management feature called Thermal Monitor is available on the processor. It provides a thermal management approach to support the continued increases in processor frequency and performance. By using a highly accurate on-die temperature sensing circuit and a fast acting Thermal Control Circuit (TCC), the processor can rapidly initiate thermal management control. The Thermal Monitor can reduce cooling solution cost, by allowing thermal designs to target TDP. The processor also supports an additional power reduction capability known as Thermal Monitor 2 described in Section 4.2.3. 4.2 Thermal Monitor Implementation The Thermal Monitor consists of the following components: • A highly accurate on-die temperature sensing circuit • A bi-directional signal (PROCHOT#) that indicates if the processor has exceeded its maximum temperature or can be asserted externally to activate the Thermal Control Circuit (TCC) (see Section 4.2.1 for more details on user activation of TCC via PROCHOT# signal) • A Thermal Control Circuit that will attempt to reduce processor temperature by rapidly reducing power consumption when the on-die temperature sensor indicates that it has exceeded the maximum operating point. • Registers to determine the processor thermal status. Thermal Management Logic and Thermal Monitor Feature 34 Thermal and Mechanical Design Guidelines 4.2.1 PROCHOT# Signal The primary function of the PROCHOT# signal is to provide an external indication the processor has reached the TCC activation temperature. While PROCHOT# is asserted, the TCC will be active. Assertion of the PROCHOT# signal is independent of any register settings within the processor. It is asserted any time the processor die temperature reaches the trip point. PROCHOT# can be configured via BIOS as an output or bi-directional signal. As an output, PROCHOT# will go active when the processor temperature of either core reaches the TCC activation temperature. As an input, assertion of PROCHOT# will activate the TCC for both cores. The TCC will remain active until the system deasserts PROCHOT#. The temperature at which the PROCHOT# signal goes active is individually calibrated during manufacturing. Once configured, the processor temperature at which the PROCHOT# signal is asserted is not re-configurable. One application of the Bi-directional PROCHOT# is for the thermal protection of voltage regulators (VR). System designers can implement a circuit to monitor the VR temperature and activate the TCC when the temperature limit of the VR is reached. By asserting PROCHOT# (pulled-low) which activates the TCC, the VR can cool down as a result of reduced processor power consumption. Bi-directional PROCHOT# can allow VR thermal designs to target maximum sustained current instead of maximum current. Systems should still provide proper cooling for the VR, and rely on bidirectional PROCHOT# signal only as a backup in case of system cooling failure. Note: A thermal solution designed to meet the thermal profile specifications should rarely experience activation of the TCC as indicated by the PROCHOT# signal going active. 4.2.2 Thermal Control Circuit The Thermal Control Circuit portion of the Thermal Monitor must be enabled for the processor to operate within specifications. The Thermal Monitor’s TCC, when active, will attempt to lower the processor temperature by reducing the processor power consumption. There are two methods by which TCC can reduce processor power dissipation. These methods are referred to as Thermal Monitor 1 (TM1) and Thermal Monitor 2 (TM2). 4.2.2.1 Thermal Monitor In the original implementation of thermal monitor this is done by changing the duty cycle of the internal processor clocks, resulting in a lower effective frequency. When active, the TCC turns the processor clocks off and then back on with a predetermined duty cycle. The duty cycle is processor specific, and is fixed for a particular processor. The maximum time period the clocks are disabled is ~3 μs. This time period is frequency dependent and higher frequency processors will disable the internal clocks for a shorter time period. Figure 4-1 illustrates the relationship between the internal processor clocks and PROCHOT#. Performance counter registers, status bits in model specific registers (MSRs), and the PROCHOT# output pin are available to monitor the Thermal Monitor behavior. Thermal Management Logic and Thermal Monitor Feature Thermal and Mechanical Design Guidelines 35 Figure 4-1. Thermal Monitor Control PROCHOT# Resultant internal clock Normal clock Internal clock Duty cycle control 4.2.3 Thermal Monitor 2 The second method of power reduction is TM2. TM2 provides an efficient means of reducing the power consumption within the processor and limiting the processor temperature. When TM2 is enabled, and a high temperature situation is detected, the enhanced TCC will be activated. The enhanced TCC causes the processor to adjust its operating frequency (by dropping the bus-to-core multiplier to its minimum available value) and input voltage identification (VID) value. This combination of reduced frequency and VID results in a reduction in processor power consumption. A processor enabled for TM2 includes two operating points, each consisting of a specific operating frequency and voltage. The first operating point represents the normal operating condition for the processor. The second operating point consists of both a lower operating frequency and voltage. When the TCC is activated, the processor automatically transitions to the new frequency. This transition occurs very rapidly (on the order of 5 microseconds). During the frequency transition, the processor is unable to service any bus requests, all bus traffic is blocked. Edge-triggered interrupts will be latched and kept pending until the processor resumes operation at the new frequency. Once the new operating frequency is engaged, the processor will transition to the new core operating voltage by issuing a new VID code to the voltage regulator. The voltage regulator must support VID transitions in order to support TM2. During the voltage change, it will be necessary to transition through multiple VID codes to reach the target operating voltage. Each step will be one VID table entry (i.e. 12.5 mV steps). The processor continues to execute instructions during the voltage transition. Operation at the lower voltage reduces the power consumption of the processor, providing a temperature reduction. Thermal Management Logic and Thermal Monitor Feature 36 Thermal and Mechanical Design Guidelines Once the processor has sufficiently cooled, and a minimum activation time has expired, the operating frequency and voltage transition back to the normal system operating point. Transition of the VID code will occur first, in order to insure proper operation once the processor reaches its normal operating frequency. Refer to Figure 4-2 for an illustration of this ordering. Figure 4-2. Thermal Monitor 2 Frequency and Voltage Ordering VID Frequency Temperature TTM2 f MAX f TM2 VID VIDTM2 PROCHOT# Time Refer to the datasheet for further information on TM2. 4.2.4 Operation and Configuration Thermal Monitor must be enabled to ensure proper processor operation. The Thermal Control Circuit feature can be configured and monitored in a number of ways. OEMs are required to enable the Thermal Control Circuit while using various registers and outputs to monitor the processor thermal status. The Thermal Control Circuit is enabled by the BIOS setting a bit in an MSR (model specific register). Enabling the Thermal Control Circuit allows the processor to attempt to maintain a safe operating temperature without the need for special software drivers or interrupt handling routines. When the Thermal Control Circuit has been enabled, processor power consumption will be reduced after the thermal sensor detects a high temperature, i.e. PROCHOT# assertion. The Thermal Control Circuit and PROCHOT# transitions to inactive once the temperature has been reduced below the thermal trip point, although a small time-based hysteresis has been included to prevent multiple PROCHOT# transitions around the trip point. External hardware can monitor PROCHOT# and generate an interrupt whenever there is a transition from active-toinactive or inactive-to-active. PROCHOT# can also be configured to generate an internal interrupt which would initiate an OEM supplied interrupt service routine. Thermal Management Logic and Thermal Monitor Feature Thermal and Mechanical Design Guidelines 37 Regardless of the configuration selected, PROCHOT# will always indicate the thermal status of the processor. The power reduction mechanism of thermal monitor can also be activated manually using an “on-demand” mode. Refer to Section 4.2.5 for details on this feature. 4.2.5 On-Demand Mode For testing purposes, the thermal control circuit may also be activated by setting bits in the ACPI MSRs. The MSRs may be set based on a particular system event (e.g., an interrupt generated after a system event), or may be set at any time through the operating system or custom driver control thus forcing the thermal control circuit on. This is referred to as “on-demand” mode. Activating the thermal control circuit may be useful for thermal solution investigations or for performance implication studies. When using the MSRs to activate the on-demand clock modulation feature, the duty cycle is configurable in steps of 12.5%, from 12.5% to 87.5%. For any duty cycle, the maximum time period the clocks are disabled is ~3 μs. This time period is frequency dependent, and decreases as frequency increases. To achieve different duty cycles, the length of time that the clocks are disabled remains constant, and the time period that the clocks are enabled is adjusted to achieve the desired ratio. For example, if the clock disable period is 3 µs, and a duty cycle of ¼ (25%) is selected, the clock on time would be reduced to approximately 1 μs [on time (1 μs) ÷ total cycle time (3 + 1) μs = ¼ duty cycle]. Similarly, for a duty cycle of 7/8 (87.5%), the clock on time would be extended to 21 μs [21 ÷ (21 + 3) = 7/8 duty cycle]. In a high temperature situation, if the thermal control circuit and ACPI MSRs (automatic and on-demand modes) are used simultaneously, the fixed duty cycle determined by automatic mode would take precedence. Note: On-demand mode can not activate the power reduction mechanism of Thermal Monitor 2 4.2.6 System Considerations Intel requires the Thermal Monitor and Thermal Control Circuit to be enabled for all processors. The thermal control circuit is intended to protect against short term thermal excursions that exceed the capability of a well designed processor thermal solution. Thermal Monitor should not be relied upon to compensate for a thermal solution that does not meet the thermal profile up to the thermal design power (TDP). Each application program has its own unique power profile, although the profile has some variability due to loop decisions, I/O activity and interrupts. In general, compute intensive applications with a high cache hit rate dissipate more processor power than applications that are I/O intensive or have low cache hit rates. The processor TDP is based on measurements of processor power consumption while running various high power applications. This data is used to determine those applications that are interesting from a power perspective. These applications are then evaluated in a controlled thermal environment to determine their sensitivity to activation of the thermal control circuit. This data is used to derive the TDP targets published in the processor datasheet. Thermal Management Logic and Thermal Monitor Feature 38 Thermal and Mechanical Design Guidelines A system designed to meet the thermal profile specification published in the processor datasheet greatly reduces the probability of real applications causing the thermal control circuit to activate under normal operating conditions. Systems that do not meet these specifications could be subject to more frequent activation of the thermal control circuit depending upon ambient air temperature and application power profile. Moreover, if a system is significantly under designed, there is a risk that the Thermal Monitor feature will not be capable of reducing the processor power and temperature and the processor could shutdown and signal THERMTRIP#. For information regarding THERMTRIP#, refer to the processor datasheet and to Section 4.2.8 of this Thermal Design Guidelines. 4.2.7 Operating System and Application Software Considerations The Thermal Monitor feature and its thermal control circuit work seamlessly with ACPI compliant operating systems. The Thermal Monitor feature is transparent to application software since the processor bus snooping, ACPI timer, and interrupts are active at all times. 4.2.8 THERMTRIP# Signal In the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon temperature has exceeded the TCC activation temperature by approximately 20 to 25 °C. At this point the system bus signal THERMTRIP# goes active and power must be removed from the processor. THERMTRIP# activation is independent of processor activity and does not generate any bus cycles. Refer to the processor datasheet for more information about THERMTRIP#. The temperature where the THERMTRIP# signal goes active is individually calibrated during manufacturing and once configuration can not be changed. 4.2.9 Cooling System Failure Warning It may be useful to use the PROCHOT# signal as an indication of cooling system failure. Messages could be sent to the system administrator to warn of the cooling failure, while the thermal control circuit would allow the system to continue functioning or allow a normal system shutdown. If no thermal management action is taken, the silicon temperature may exceed the operating limits, causing THERMTRIP# to activate and shut down the processor. Regardless of the system design requirements or thermal solution ability, the Thermal Monitor feature must still be enabled to ensure proper processor operation. 4.2.10 Digital Thermal Sensor Multiple digital thermal sensors can be implemented within the package without adding a pair of signal pins per sensor as required with the thermal diode. The digital thermal sensor is easier to place in thermally sensitive locations of the processor than the thermal diode. This is achieved due to a smaller foot print and decreased sensitivity to noise. Since the DTS is factory set on a per-part basis there is no need for the health monitor components to be updated at each processor family Thermal Management Logic and Thermal Monitor Feature Thermal and Mechanical Design Guidelines 39 The processor introduces the Digital Thermal Sensor (DTS) as the on-die sensor to use for fan speed control (FSC). The DTS will eventually replace the on-die thermal diode used in pervious products. The processor will have both the DTS and thermal diode enabled. The DTS is monitoring the same sensor that activates the TCC (see Section 4.2.2). Readings from the DTS are relative to the activation of the TCC. The DTS value where TCC activation occurs is 0 (zero). A TCONTROL value will be provided for use with DTS. The usage model for TCONTROL with the DTS is the same as with the on-die thermal diode: • If the Digital thermal sensor is less than TCONTROL, the fan speed can be reduced. • If the Digital thermal sensor is greater than or equal to TCONTROL, then TC must be maintained at or below the Thermal Profile for the measured power dissipation. The calculation of TCONTROL is slightly different from previous product. There is no base value to sum with the TOFFSET located in the same MSR as used in previous processors. The BIOS only needs to read the TOFFSET MSR and provide this value to the fan speed control device. Figure 4-3.

The TCONTROL in the MSR is relevant only to the DTS. 4.2.11 Platform Environmental Control Interface (PECI) The PECI interface is a proprietary single wire bus between the processor and the chipset or other health monitoring device. At this time the digital thermal sensor is the only data being transmitted. For an overview of the PECI interface see PECI Feature Set Overview. For additional information on the PECI, see the datasheet. The PECI bus is available on pin G5 of the LGA 775 socket. Intel chipsets beginning with the ICH8 have included PECI host controller. The PECI interface and the Manageability Engine are key elements to the Intel® Quiet System Technology (Intel® Thermal Management Logic and Thermal Monitor Feature 40 Thermal and Mechanical Design Guidelines QST), see Chapter 7 and the Intel® Quiet System Technology Configuration and Tuning Manual. Intel has worked with many vendors that provide fan speed control devices to provide PECI host controllers. Please consult the local representative for your preferred vendor for their product plans and availability. § Balanced Technology Extended (BTX) Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 41 5 Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 5.1 Overview of the Balanced Technology Extended (BTX) Reference Design The reference thermal module assembly is a Type II BTX compliant design and is compliant with the reference BTX motherboard keep-out and height recommendations defined Section 6.6. The solution comes as an integrated assembly. An isometric view of the assembly is provided Figure 5-4. 5.1.1 Target Heatsink Performance Table 5-1 provides the target heatsink performance for the processor with the BTX boundary conditions. The results will be evaluated using the test procedure described in Section 5.2. The table also includes a TA assumption of 35.5 °C for the Intel reference thermal solution at the processor fan heatsink inlet discussed Section 3.3. The analysis assumes a uniform external ambient temperature to the chassis of 35 °C across the fan inlet, resulting in a temperature rise, TR, of 0.5 °C. Meeting TA and ΨCA targets can maximize processor performance (refer to Sections 2.2, 2.4. and Chapter 4). Minimizing TR, can lead to improved acoustics.

Performance targets (Ψ ca) as measured with a live processor at TDP. 2. The difference in Ψ ca between the Intel® Core™2 Duo 4 MB and 2 MB is due to a slight difference in the die size. 3. BTX Type II reference TMA is the higher thermal solution performance of the Intel® Core™2 Duo processor with 4 MB / 2 MB cache at Tc-max of 72.0 °C, Intel® Core™2 Duo processor with 2 MB cache at Tc-max of 73.3 °C, Intel® Pentium® Dual Core processor E2000 series at Tc-max of 73.3 °C, and Intel® Celeron® Dual-Core Processor E1000 Series at Tc-max of 73.3° C. Customers can generate an improvement in cost saving for these processors to likely use the designs with the cheater TIM, the cheater fan and the lower fin density extrusion. 5.1.2 Acoustics To optimize acoustic emission by the fan heatsink assembly, the Type II reference design implements a variable speed fan. A variable speed fan allows higher thermal performance at higher fan inlet temperatures (TA) and the appropriate thermal performance with improved acoustics at lower fan inlet temperatures. Using the example in Table 5-2 for the Intel® Core™2 Duo processor with 4 MB cache at Tc-max of 60.1 °C the required fan speed necessary to meet thermal specifications can be controlled by the fan inlet temperature and should comply with the following requirements. Balanced Technology Extended (BTX) Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 43 Table 5-2.

Acoustic performance is defined in terms of measured sound power (LwA) as defined in ISO 9296 standard, and measured according to ISO 7779. 2. Acoustic testing will be for the TMA only when installed in a BTX S2 chassis for Case 1 and 3 3. Acoustics testing for Case 2 will be system level in the same a BTX S2 reference chassis and commercially available power supply. Acoustic data for Case 2 will be provided in the validation report but this condition is not a target for the design. The acoustic model is predicting that the power supply fan will be the acoustic limiter. 4. The fan speeds (RPM) are estimates for one of the two reference fans and will be adjusted to meet thermal performance targets then acoustic target during validation. The designer should identify the fan speed required to meet the effective fan curve shown in Section 5.1.3 While the fan hub thermistor helps optimize acoustics at high processor workloads by adapting the maximum fan speed to support the processor thermal profile, additional acoustic improvements can be achieved at lower processor workload by using the TCONTROL specifications described in Section 2.2.3. Intel’s recommendation is to use the fan with 4 Wire PWM Controlled to implement fan speed control capability based the digital thermal sensor. Refer to Chapter 7 for further details. Note: Appendix G gives detailed fan performance for the Intel reference thermal solutions with 4 Wire PWM Controlled fan. Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 44 Thermal and Mechanical Design Guidelines 5.1.3 Effective Fan Curve The TMA must fulfill the processor cooling requirements shown in Table 5-1 when it is installed in a functional BTX system. When installed in a system, the TMA must operate against the backpressure created by the chassis impedance (due to vents, bezel, peripherals, etc…) and will operate at lower net airflow than if it were tested outside of the system on a bench top or open air environment. Therefore an allowance must be made to accommodate or predict the reduction in Thermal Module performance due to the reduction in heatsink airflow from chassis impedance. For this reason, it is required that the Thermal Module satisfy the prescribed ΨCA requirements when operating against an impedance that is characteristic for BTX platforms. Because of the coupling between TMA thermal performance and system impedance, the designer should understand the TMA effective fan curve. This effective fan curve represents the performance of the fan component AND the impedance of the stator, heatsink, duct, and flow partitioning devices. The BTX system integrator will be able to evaluate a TMA based on the effective fan curve of the assembly and the airflow impedance of their target system. Note: It is likely that at some operating points the fans speed will be driven by the system airflow requirements and not the processor thermal limits. Figure 5-1 shows the effective fan curve for the reference design TMA. These curves are based on analysis. The boundary conditions used are the S2 6.9L reference chassis, the reference TMA with the flow portioning device, extrusion and an AVC Type II fan geometry. When selecting a fan for use in the TMA care should be taken that similar effective fan curves can be achieved. Final verification requires the overlay of the Type II MASI curve to ensure thermal compliance.

The reference design TMA will include a flow partitioning device to ensure an appropriate airflow balance between the TMA and the VR. In validation the need for this component will be evaluated. The BTX thermal management strategy relies on the Thermal Module to provide effective cooling for the voltage regulator (VR) chipset and system memory components on the motherboard. The Thermal Module is required to have features that allow for airflow to bypass the heatsink and flow over the VR region on both the primary and secondary sides of the board. The following requirements apply to VR cooling. Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 46 Thermal and Mechanical Design Guidelines Table 5-3. VR Airflow Requirements Item Target Minimum VR bypass airflow for 775_VR_CONFIG_06 processors 2.4 CFM NOTES: 1. This is the recommended airflow rate that should be delivered to the VR when the VR power is at a maximum in order to support the 775_VR_CONFIG_06 processors at TDP power dissipation and the chassis external environment temperature is at 35 ºC. Less airflow is necessary when the VR power is not at a maximum or if the external ambient temperature is less than 35 ºC. 2. This recommended airflow rate is based on the requirements for the Intel® 965 Express Chipset Family. 5.1.5 Altitude The reference TMA will be evaluated at sea level. However, many companies design products that must function reliably at high altitude, typically 1,500 m [5,000 ft] or more. Air-cooled temperature calculations and measurements at sea level must be adjusted to take into account altitude effects like variation in air density and overall heat capacity. This often leads to some degradation in thermal solution performance compared to what is obtained at sea level, with lower fan performance and higher surface temperatures. The system designer needs to account for altitude effects in the overall system thermal design to make sure that the TC requirement for the processor is met at the targeted altitude. 5.1.6 Reference Heatsink Thermal Validation The Intel reference heatsink will be validated within the specific boundary conditions based on the methodology described Section 5.2. Testing is done in a BTX chassis at ambient lab temperature. The test results, for a number of samples, will be reported in terms of a worst-case mean + 3σ value for thermal characterization parameter using real processors (based on the thermal test vehicle correction factors). 5.2 Environmental Reliability Testing 5.2.1 Structural Reliability Testing Structural reliability tests consist of unpackaged, system -level vibration and shock tests of a given thermal solution in the assembled state. The thermal solution should meet the specified thermal performance targets after these tests are conducted; however, the test conditions outlined here may differ from your own system requirements.

Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 48 Thermal and Mechanical Design Guidelines Figure 5-3. Shock Acceleration Curve 5.2.1.2.1 Recommended Test Sequence Each test sequence should start with components (i.e., motherboard, heatsink assembly, etc.) that have never been previously submitted to any reliability testing. The test sequence should always start with a visual inspection after assembly, and BIOS/CPU/Memory test (refer to Section 6.3.3). Prior to the mechanical shock & vibration test, the units under test should be preconditioned for 72 hours at 45 ºC. The purpose is to account for load relaxation during burn-in stage. The stress test should be followed by a visual inspection and then BIOS/CPU/Memory test. 5.2.1.2.2 Post-Test Pass Criteria The post-test pass criteria are: 1. No significant physical damage to the heatsink attach mechanism (including such items as clip and motherboard fasteners). 2. Heatsink must remain attached to the motherboard. 3. Heatsink remains seated and its bottom remains mated flatly against IHS surface. No visible gap between the heatsink base and processor IHS. No visible tilt of the heatsink with respect to its attach mechanism. 4. No signs of physical damage on motherboard surface due to impact of heatsink or heatsink attach mechanism. 5. No visible physical damage to the processor package. 6. Successful BIOS/Processor/memory test of post-test samples. 7. Thermal compliance testing to demonstrate that the case temperature specification can be met. Balanced Technology Extended (BTX) Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 49 5.2.2 Power Cycling Thermal performance degradation due to TIM degradation is evaluated using power cycling testing. The test is defined by 7500 cycles for the case temperature from room temperature (~23 ºC) to the maximum case temperature defined by the thermal profile at TDP. 5.2.3 Recommended BIOS/CPU/Memory Test Procedures This test is to ensure proper operation of the product before and after environmental stresses, with the thermal mechanical enabling components assembled. The test shall be conducted on a fully operational motherboard that has not been exposed to any battery of tests prior to the test being considered. Testing setup should include the following components, properly assembled and/or connected: • Appropriate system motherboard • Processor • All enabling components, including socket and thermal solution parts • Power supply • Disk drive • Video card • DIMM • Keyboard • Monitor The pass criterion is that the system under test shall successfully complete the checking of BIOS, basic processor functions and memory, without any errors. 5.3 Material and Recycling Requirements Material shall be resistant to fungal growth. Examples of non-resistant materials include cellulose materials, animal and vegetable based adhesives, grease, oils, and many hydrocarbons. Synthetic materials such as PVC formulations, certain polyurethane compositions (e.g., polyester and some polyethers), plastics which contain organic fillers of laminating materials, paints, and varnishes also are susceptible to fungal growth. If materials are not fungal growth resistant, then MILSTD-810E, Method 508.4 must be performed to determine material performance. Material used shall not have deformation or degradation in a temperature life test. Any plastic component exceeding 25 grams must be recyclable per the European Blue Angel recycling standards. Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 50 Thermal and Mechanical Design Guidelines 5.4 Safety Requirements Heatsink and attachment assemblies shall be consistent with the manufacture of units that meet the safety standards: • UL Recognition-approved for flammability at the system level. All mechanical and thermal enabling components must be a minimum UL94V-2 approved. • CSA Certification. All mechanical and thermal enabling components must have CSA certification. • All components (in particular the heatsink fins) must meet the test requirements of UL1439 for sharp edges. • If the International Accessibility Probe specified in IEC 950 can access the moving parts of the fan, consider adding safety feature so that there is no risk of personal injury. 5.5 Geometric Envelope for Intel Reference BTX Thermal Module Assembly Figure 7-50 through Figure 7-54 in Appendix H gives the motherboard keep-out information for the BTX thermal mechanical solutions. Additional information on BTX design considerations can be found in Balanced Technology Extended (BTX) System Design Guide available at http://www.formfactors.org.

Balanced Technology Extended (BTX) Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 51 5.6 Preload and TMA Stiffness 5.6.1 Structural Design Strategy Structural design strategy for the Intel Type II TMA is to minimize upward board deflection during shock to help protect the LGA775 socket. BTX thermal solutions utilize the SRM and TMA that together resists local board curvature under the socket and minimize, board deflection (Figure 5-5). In addition, a moderate preload provides initial downward deflection. Figure 5-5. Upward Board Deflection During Shock 5.6.2 TMA Preload versus Stiffness The Thermal Module assembly is required to provide a static preload to ensure protection against fatigue failure of socket solder joint. The allowable preload range for BTX platforms is provided in Table 5-4, but the specific target value is a function of the Thermal Module effective stiffness. The solution space for the Thermal Module effective stiffness and applied preload combinations is shown by the shaded region of Figure 5-6. This solution space shows that the Thermal Module assembly must have an effective stiffness that is sufficiently large such that the minimum preload determined from the relationship requirement in Figure 5-6 does not exceed the maximum allowed preload shown in Table 5-4. Furthermore, if the Thermal Module effective stiffness is so large that the minimum preload determined from Figure 5-6 is below the minimum required value given in Less curvature in region between SRM and TMA Shock Load Balanced Technology Extended (BTX) Thermal/Mechanical Design Information 52 Thermal and Mechanical Design Guidelines Table 5-4, then the Thermal Module should be re-designed to have a preload that lies within the range given in Table 5-4, allowing for preload tolerances. Table 5-4. Processor Preload Limits Parameter Minimum Required Maximum Allowed Notes Processor Preload 98 N [22 lbf] 222 N [50 lbf] 1 NOTES: 1. These values represent upper and lower bounds for the processor preload. The nominal preload design point for the Thermal Module is based on a combination of requirements of the TIM, ease of assembly and the Thermal Module effective stiffness. Figure 5-6. Minimum Required Processor Preload to Thermal Module Assembly Stiffness NOTES: 1. The shaded region shown is the acceptable domain for Thermal Module assembly effective stiffness and processor preload combinations. The Thermal Module design should have a design preload and stiffness that lies within this region. The design tolerance for the preload and TMA stiffness should also reside within this boundary. Note that the lower and upper horizontal boundaries represent the preload limits provided in Table 5-4. The equation for the left hand boundary is described in note 2. 2. The equation for this section of the preload-Thermal Module stiffness boundary is given by the following relationship: Min Preload = 1.38E-3*k^2 – 1.18486k + 320.24753 for k < 300 N/mm where k is the Thermal Module assembly effective stiffness. Please note that this equation is only valid in the stiffness domain of 93N/mm < k < 282N/mm. This equation would not apply, for example, for TMA stiffness less than 93N/mm, 3. The target stiffness for the 65W Type II TMA reference design is 484 N/mm (2764 lb / in). Note: These preload and stiffness recommendations are specific to the TMA mounting scheme that meets the BTX Interface Specification and Support Retention Mechanism (SRM) Design Guide. For TMA mounting schemes that use only the motherboard Balanced Technology Extended (BTX) Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 53 mounting hole position for TMA attach, the required preload is approximately 10-15N greater than the values stipulated in Figure 5-6; however, Intel has not conducted any validation testing with this TMA mounting scheme.

The E18764-001 reference design takes advantage of the cost savings for the several features of the design including the reduced heatsink height, inserted aluminum core, and the new TIM material (Dow Corning TC-1996 grease, see Figure 6-3).

ATX Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 59 6.2.2 Acoustics To optimize acoustic emission by the fan heatsink assembly, the reference design implements a variable speed fan. A variable speed fan allows higher thermal performance at higher fan inlet temperatures (TA) and lower thermal performance with improved acoustics at lower fan inlet temperatures. The required fan speed necessary to meet thermal specifications can be controlled by the fan inlet temperature and should comply with requirements listed in the following table. Table 6-3.

Acoustic performance is defined in terms of measured sound power (LwA) as defined in ISO 9296 standard, and measured according to ISO 7779. While the fan hub thermistor helps optimize acoustics at high processor workloads by adapting the maximum fan speed to support the processor thermal profile, additional acoustic improvements can be achieved at lower processor workload by using the ATX Thermal/Mechanical Design Information 60 Thermal and Mechanical Design Guidelines TCONTROL specifications described in Section 2.2.3. Intel recommendation is to use the fan with 4 Wire PWM Controlled to implement fan speed control capability based digital thermal sensor temperature. Refer to Chapter 7 for further details. Note: Appendix G gives detailed fan performance for the Intel reference thermal solutions with 4 Wire PWM Controlled fan. 6.2.3 Altitude Many companies design products that must function reliably at high altitude, typically 1,500 m [5,000 ft] or more. Air-cooled temperature calculations and measurements at the test site elevation must be adjusted to take into account altitude effects like variation in air density and overall heat capacity. This often leads to some degradation in thermal solution performance compared to what is obtained at sea level, with lower fan performance and higher surface temperatures. The system designer needs to account for altitude effects in the overall system thermal design to make sure that the TC requirement for the processor is met at the targeted altitude. 6.2.4 Heatsink Thermal Validation Intel recommends evaluation of the heatsink within the specific boundary conditions based on the methodology described Section 6.3. Testing is done on bench top test boards at ambient lab temperature. In particular, for the reference heatsink, the Plexiglas* barrier is installed 81.28 mm [3.2 in] above the motherboard (refer to Sections 3.3 and 6.6). The test results, for a number of samples, are reported in terms of a worst-case mean + 3σ value for thermal characterization parameter using real processors (based on the thermal test vehicle correction factors). Note: The above 81.28 mm obstruction height that is used for testing complies with the recommended obstruction height of 88.9 mm for the ATX form factor. However, it would conflict with systems in strict compliance with the ATX specification which allows an obstruction as low as 76.2 mm above the motherboard surface in Area A. ATX Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 61 6.3 Environmental Reliability Testing 6.3.1 Structural Reliability Testing Structural reliability tests consist of unpackaged, board-level vibration and shock tests of a given thermal solution in the assembled state. The thermal solution should meet the specified thermal performance targets after these tests are conducted; however, the test conditions outlined here may differ from your own system requirements. 6.3.1.1 Random Vibration Test Procedure Duration: 10 min/axis, 3 axes Frequency Range: 5 Hz to 500 Hz Power Spectral Density (PSD) Profile: 3.13 G RMS Figure 6-4.

The test sequence should always start with a visual inspection after assembly, and BIOS/CPU/Memory test (refer to Section 6.3.3). Prior to the mechanical shock & vibration test, the units under test should be preconditioned for 72 hours at 45 ºC. The purpose is to account for load relaxation during burn-in stage. The stress test should be followed by a visual inspection and then BIOS/CPU/Memory test. 6.3.1.2.2 Post-Test Pass Criteria The post-test pass criteria are: 1. No significant physical damage to the heatsink attach mechanism (including such items as clip and motherboard fasteners). 2. Heatsink must remain attached to the motherboard. 3. Heatsink remains seated and its bottom remains mated flatly against IHS surface. No visible gap between the heatsink base and processor IHS. No visible tilt of the heatsink with respect to its attach mechanism. 4. No signs of physical damage on motherboard surface due to impact of heatsink or heatsink attach mechanism. 5. No visible physical damage to the processor package. 6. Successful BIOS/Processor/memory test of post-test samples. 7. Thermal compliance testing to demonstrate that the case temperature specification can be met. ATX Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 63 6.3.2 Power Cycling Thermal performance degradation due to TIM degradation is evaluated using power cycling testing. The test is defined by 7500 cycles for the case temperature from room temperature (~23 ºC) to the maximum case temperature defined by the thermal profile at TDP. 6.3.3 Recommended BIOS/CPU/Memory Test Procedures This test is to ensure proper operation of the product before and after environmental stresses, with the thermal mechanical enabling components assembled. The test shall be conducted on a fully operational motherboard that has not been exposed to any battery of tests prior to the test being considered. Testing setup should include the following components, properly assembled and/or connected: • Appropriate system motherboard • Processor • All enabling components, including socket and thermal solution parts • Power supply • Disk drive • Video card • DIMM • Keyboard • Monitor The pass criterion is that the system under test shall successfully complete the checking of BIOS, basic processor functions and memory, without any errors. 6.4 Material and Recycling Requirements Material shall be resistant to fungal growth. Examples of non-resistant materials include cellulose materials, animal and vegetable based adhesives, grease, oils, and many hydrocarbons. Synthetic materials such as PVC formulations, certain polyurethane compositions (e.g., polyester and some polyethers), plastics which contain organic fillers of laminating materials, paints, and varnishes also are susceptible to fungal growth. If materials are not fungal growth resistant, then MILSTD-810E, Method 508.4 must be performed to determine material performance. Material used shall not have deformation or degradation in a temperature life test. Any plastic component exceeding 25 grams must be recyclable per the European Blue Angel recycling standards. ATX Thermal/Mechanical Design Information 64 Thermal and Mechanical Design Guidelines 6.5 Safety Requirements Heatsink and attachment assemblies shall be consistent with the manufacture of units that meet the safety standards: • UL Recognition-approved for flammability at the system level. All mechanical and thermal enabling components must be a minimum UL94V-2 approved. • CSA Certification. All mechanical and thermal enabling components must have CSA certification. • All components (in particular the heatsink fins) must meet the test requirements of UL1439 for sharp edges. • If the International Accessibility Probe specified in IEC 950 can access the moving parts of the fan, consider adding safety feature so that there is no risk of personal injury. 6.6 Geometric Envelope for Intel Reference ATX Thermal Mechanical Design Figure 7-47, Figure 7-48 and Figure 7-49 in Appendix H gives detailed reference ATX/μATX motherboard keep-out information for the reference thermal/mechanical enabling design. These drawings include height restrictions in the enabling component region. The maximum height of the reference solution above the motherboard is 71.12 mm [2.8 inches], and is compliant with the motherboard primary side height constraints defined in the ATX Specification revision 2.1 and the microATX Motherboard Interface Specification revision 1.1 found at http://www.formfactors.org. The reference solution requires a chassis obstruction height of at least 81.28 mm [3.2 inches], measured from the top of the motherboard (refer to Sections 3.3 and 6.2.4). This allows for appropriate fan inlet airflow to ensure fan performance, and therefore overall cooling solution performance. This is compliant with the recommendations found in both ATX Specification V2.1 and microATX Motherboard Interface Specification V1.1 documents. ATX Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 65 6.7 Reference Attach Mechanism 6.7.1 Structural Design Strategy Structural design strategy for the reference design is to minimize upward board deflection during shock to help protect the LGA775 socket. The reference design uses a high clip stiffness that resists local board curvature under the heatsink, and minimizes, in particular, upward board deflection (Figure 6-6). In addition, a moderate preload provides initial downward deflection. Figure 6-6. Upward Board Deflection During Shock The target metal clip nominal stiffness is 540 N/mm [3100 lb/in]. The combined target for reference clip and fasteners nominal stiffness is 380 N/mm [2180 lb/in]. The nominal preload provided by the reference design is 191.3 N ± 44.5 N [43 lb ± 10 lb]. Note: Intel reserves the right to make changes and modifications to the design as necessary to the reference design, in particular the clip and fastener. Less curvature in region under stiff clip Shock Load ATX Thermal/Mechanical Design Information 66 Thermal and Mechanical Design Guidelines 6.7.2 Mechanical Interface to the Reference Attach Mechanism The attach mechanism component from the reference design can be used by other 3rd party cooling solutions. The attach mechanism consists of: • A metal attach clip that interfaces with the heatsink core, see Appendix H, Figure 7-55 and Figure 7-56 for the component drawings. • Four plastic fasteners, see Appendix H, Figure 7-57, Figure 7-58, Figure 7-59 and Figure 7-60 for the component drawings. The clip is assembled to heatsink during copper core insertion, and is meant to be trapped between the core shoulder and the extrusion as shown in Figure 6-7. Figure 6-7. Reference Clip/Heatsink Assembly Core shoulder traps clip in place Clip The mechanical interface with the reference attach mechanism is defined in Figure 6-8 and Figure 6-9. Complying with the mechanical interface parameters is critical to generating a heatsink preload compliant with the minimum preload requirement given in Section 2.1.2.2. Additional requirements for the reference attach mechanism (clip and fasteners) include: • Heatsink/fan mass ≤ 550 g (i.e., total assembly mass, including clip and fasteners < 595 g • Whole assembly center of gravity ≤ 25.4 mm, measured from the top of the IHS ⎯ Whole assembly = Heatsink + Fan + Attach clip + Fasteners ATX Thermal/Mechanical Design Information Thermal and Mechanical Design Guidelines 67 Figure 6-8.

It is composed of an Intel® Management Engine (ME) in the Graphics Memory Controller Hub (GMCH) which executes the Intel® Quiet System Technology (Intel® QST) algorithm and the ICH8 containing the sensor bus and fan control circuits. The ME provides integrated fan speed control in lieu of the mechanisms available in a SIO or a stand-alone ASIC. The Intel QST is time based as compared to the linear or state control used by the current generation of FSC devices. A short discussion of Intel QST will follow along with thermal solution design recommendations. For a complete discussion of programming the Intel QST in the ME please consult the Intel® Quiet System Technology (Intel® QST) Configuration and Tuning Manual. Note: Fan speed control algorithms and Intel QST in particular rely on a thermal solution being compliant to the processor thermal profile. It is unlikely that any fan speed control algorithm can compensate for a non-compliant thermal solution. See Chapter 5 and Chapter 6 for thermal solution requirements that should be met before evaluating or configuring a system with Intel QST. 7.1 Intel® QST Algorithm The objective of Intel QST is to minimize the system acoustics by more closely controlling the thermal sensors to the corresponding processor or chipset device TCONTROL value. This is achieved by the use of a Proportional-Integral-Derivative (PID) control algorithm and a Fan Output Weighting Matrix. The PID algorithm takes into account the difference between the current temperature and the target (TCONTROL), the rate of change and direction of change to minimize the required fan speed change. The Fan Output Weighting Matrix uses the effects of each fan on a thermal sensor to minimize the required fan speed changes Figure 7-1 shows in a very simple manner how Intel QST works. See the Intel Quiet System Technology (Intel® QST) Configuration and Tuning Manual for a detail discussion of the inputs and response. Intel® Quiet System Technology (Intel® QST) 70 Thermal and Mechanical Design Guidelines Figure 7-1. Intel® QST Overview Fan to sensor Relationship (Output Weighting Matrix) Temperature sensing and response Calculations (PID) Fan Commands (PID) Fans Temperature Sensors Intel® QST System Response PECI / SST PWM 7.1.1 Output Weighting Matrix Intel QST provides an Output Weighting Matrix that provides a means for a single thermal sensor to affect the speed of multiple fans. An example of how the matrix could be used is if a sensor located next to the memory is sensitive to changes in both the processor heatsink fan and a 2nd fan in the system. By placing a factor in this matrix additional the Intel QST could command the processor thermal solution fan and this 2nd fan to both accelerate a small amount. At the system level these two small changes can result in a smaller change in acoustics than having a single fan respond to this sensor. 7.1.2 Proportional-Integral-Derivative (PID) The use of Proportional-Integral-Derivative (PID) control algorithms allow the magnitude of fan response to be determined based upon the difference between current temperature readings and specific temperature targets. A major advantage of a PID Algorithm is the ability to control the fans to achieve sensor temperatures much closer to the TCONTROL. Figure 7-2 is an illustration of the PID fan control algorithm. As illustrated in the figure, when the actual temperature is below the target temperature, the fan will slow down. The current FSC devices have a fixed temperature vs. PWM output relationship and miss this opportunity to achieve additional acoustic benefits. As the actual temperature starts ramping up and approaches the target temperature, the algorithm will instruct the fan to speed up gradually, but will not abruptly increase the fan speed to respond to the condition. It can allow an overshoot over the target temperature for a short period of time while ramping up the fan to bring the actual temperature to the Intel® Quiet System Technology (Intel® QST) Thermal and Mechanical Design Guidelines 71 target temperature. As a result of its operation, the PID control algorithm can enable an acoustic-friendly platform. Figure 7-2. PID Controller Fundamentals Proportional Error Derivative (Slope) Integral (time averaged) RPM Temperature Time + dPWM - dPWM Actual Temperature Fan Speed Limit Temperature For a PID algorithm to work limit temperatures are assigned for each temperature sensor. For Intel QST, the TCONTROL for the processor and chipset are to be used as the limit temperature. The ME will measure the error, slope and rate of change using the following equations: • Proportional Error (P) = TLIMIT – TACTUAL • Integral (I) = Time averaged error • Derivative (D) = ΔTemp / ΔTime Three gain values are used to control response of algorithm. • Kp = proportional gain • Ki = Integral gain • Kd = derivative gain The Intel® Quiet System Technology (Intel® QST) Configuration and Tuning Manual provides initial values for the each of the gain constants. In addition it provides a methodology to tune these gain values based on system response. Finally the fan speed change will be calculated using the following formula: ΔPWM = -P*(Kp) – I*(Ki) + D*(Kd) Intel® Quiet System Technology (Intel® QST) 72 Thermal and Mechanical Design Guidelines 7.2 Board and System Implementation of Intel® QST To implement the board must be configured as shown in Figure 7-3 and listed below: • ME system (S0-S1) with Controller Link connected and powered • DRAM with Channel A DIMM 0 installed and 2MB reserved for Intel® QST FW execution • SPI Flash with sufficient space for the Intel® QST Firmware • SST-based thermal sensors to provide board thermal data for Intel® QST algorithms • Intel® QST firmware Figure 7-3. Intel® QST Platform Requirements Note: Simple Serial Transport (SST) is a single wire bus that is included in the ICH8 to provide additional thermal and voltage sensing capability to the Intel® Management Engine (ME) Intel® Quiet System Technology (Intel® QST) Thermal and Mechanical Design Guidelines 73 Figure 7-4 shows the major connections for a typical implementation that can support processors with Digital thermal sensor or a thermal diode. In this configuration a SST Thermal Sensor has been added to read the on-die thermal diode that is in all of the processors in the 775-land LGA packages shipped before the Intel® Core™2 Duo processor. With the proper configuration information the ME can be accommodate inputs from PECI or SST for the processor socket. Additional SST sensors can be added to monitor system thermal (see Appendix F for BTX recommendations for placement). Figure 7-4. Example Acoustic Fan Speed Control Implementation Intel has engaged with a number of major manufacturers of thermal / voltage sensors to provide devices for the SST bus. Contact your Intel Field Sales representative for the current list of manufacturers and visit their web sites or local sales representatives for a part suitable for your design. Intel® Quiet System Technology (Intel® QST) 74 Thermal and Mechanical Design Guidelines 7.3 Intel® QST Configuration and Tuning Initial configuration of the Intel QST is the responsibility of the board manufacturer. The SPI flash should be programmed with the hardware configuration of the motherboard and initial settings for fan control, fan monitoring, voltage and thermal monitoring. This initial data is generated using the Intel provided Configuration Tool. At the system integrator the Configuration Tool can be used again but this time to tune the Intel QST subsystem to reflect the shipping system configuration. In the tuning process the Intel QST can be modified to have the proper relationships between the installed fans and sensors in the shipping system. A Weighting Matrix Utility and Intel QST Log program are planned to assist in optimizing the fan management and achieve acoustic goal. See your Intel field sales representative for availability of these tools. 7.4 Fan Hub Thermistor and Intel® QST There is no closed loop control between Intel QST and the thermistor, but they can work in tandem to provide the maximum fan speed reduction. The BTX reference design includes a thermistor on the fan hub. This Variable Speed Fan curve will determine the maximum fan speed as a function of the inlet ambient temperature and by design provides a ΨCA sufficient to meet the thermal profile of the processor. Intel QST, by measuring the processor Digital thermal sensor will command the fan to reduce speed below the VSF curve in response to processor workload. Conversely if the processor workload increases the FSC will command the fan via the PWM duty cycle to accelerate the fan up to the limit imposed by the VSF curve. Care needs to be taken in BTX designs to ensure the fan speed at the minimum operating speed provides sufficient air flow to support the other system components. Figure 7-5.

Solder ball tensile stress is originally created when, after inserting a processor into the socket, the LGA775 socket load plate is actuated. In addition, solder joint shear stress is caused by coefficient of thermal expansion (CTE) mismatch induced shear loading. The solder joint compressive axial force (Faxial) induced by the heatsink preload helps to reduce the combined joint tensile and shear stress. Overall, the heatsink required preload is the minimum preload needed to meet all of the above requirements: Mechanical shock and vibration and TIM performance AND LGA775 socket protection against fatigue failure. A.2 Metric for Heatsink Preload for ATX/uATX Designs Non-Compliant with Intel® Reference Design A.2.1 Heatsink Preload Requirement Limitations Heatsink preload by itself is not an appropriate metric for solder joint force across various mechanical designs and does not take into account for example (not an exhaustive list): • Heatsink mounting hole span • Heatsink clip/fastener assembly stiffness and creep • Board stiffness and creep • Board stiffness is modified by fixtures like backing plate, chassis attach, etc. LGA775 Socket Heatsink Loading 76 Thermal and Mechanical Design Guidelines Simulation shows that the solder joint force (Faxial) is proportional to the board deflection measured along the socket diagonal. The matching of Faxial required to protect the LGA775 socket solder joint in temperature cycling is equivalent to matching a target MB deflection. Therefore, the heatsink preload for LGA775 socket solder joint protection against fatigue failure can be more generally defined as the load required to create a target board downward deflection throughout the life of the product. This board deflection metric provides guidance for mechanical designs that differ from the reference design for ATX//µATX form factor. A.2.2 Motherboard Deflection Metric Definition Motherboard deflection is measured along either diagonal (refer to Figure 7-6): d = dmax – (d1 + d2)/2 d’ = dmax – (d’1 + d’2)/2 Configurations in which the deflection is measured are defined in the Table 7-1. To measure board deflection, follow industry standard procedures (such as IPC) for board deflection measurement. Height gauges and possibly dial gauges may also be used. Table 7-1. Board Deflection Configuration Definitions Configuration Parameter Processor + Socket load plate Heatsink Parameter Name d_ref yes no BOL deflection, no preload d_BOL yes yes BOL deflection with preload d_EOL yes yes EOL deflection NOTES: BOL: Beginning of Life EOL: End of Life LGA775 Socket Heatsink Loading Thermal and Mechanical Design Guidelines 77 Figure 7-6. Board Deflection Definition d1 d2 d’1 d’2 A.2.3 Board Deflection Limits Deflection limits for the ATX/µATX form factor are: d_BOL - d_ref≥ 0.09 mm and d_EOL - d_ref ≥ 0.15 mm And d’_BOL – d’_ref≥ 0.09 mm and d_EOL’ – d_ref’ ≥ 0.15 mm NOTES: 1. The heatsink preload must remain within the static load limits defined in the processor datasheet at all times. 2. Board deflection should not exceed motherboard manufacturer specifications. LGA775 Socket Heatsink Loading 78 Thermal and Mechanical Design Guidelines A.2.4 Board Deflection Metric Implementation Example This section is for illustration only, and relies on the following assumptions: • 72 mm x 72 mm hole pattern of the reference design • Board stiffness = 900 lb/in at BOL, with degradation that simulates board creep over time ⎯ Though these values are representative, they may change with selected material and board manufacturing process. Check with your motherboard vendor. • Clip stiffness assumed constant – No creep. Using Figure 7-7, the heatsink preload at beginning of life is defined to comply with d_EOL – d_ref = 0.15 mm depending on clip stiffness assumption. Note that the BOL and EOL preload and board deflection differ. This is a result of the creep phenomenon. The example accounts for the creep expected to occur in the motherboard. It assumes no creep to occur in the clip. However, there is a small amount of creep accounted for in the plastic fasteners. This situation is somewhat similar to the reference design. The impact of the creep to the board deflection is a function of the clip stiffness: • The relatively compliant clips store strain energy in the clip under the BOL preload condition and tend to generate increasing amounts of board deflection as the motherboard creeps under exposure to time and temperature. • In contrast, the stiffer clips stores very little strain energy, and therefore do not generate substantial additional board deflection through life. NOTES: 1. Board and clip creep modify board deflection over time and depends on board stiffness, clip stiffness, and selected materials. 2. Designers must define the BOL board deflection that will lead to the correct end of life board deflection LGA775 Socket Heatsink Loading Thermal and Mechanical Design Guidelines 79 Figure 7-7. Example: Defining Heatsink Preload Meeting Board Deflection Limit A.2.5 Additional Considerations Intel recommends to design to {d_BOL - d_ref = 0.15mm} at BOL when EOL conditions are not known or difficult to assess. The following information is given for illustration only. It is based on the reference keep-out, assuming there is no fixture that changes board stiffness: d_ref is expected to be 0.18 mm on average, and be as high as 0.22 mm As a result, the board should be able to deflect 0.37 mm minimum at BOL Additional deflection as high as 0.09 mm may be necessary to account for additional creep effects impacting the board/clip/fastener assembly. As a result, designs could see as much as 0.50 mm total downward board deflection under the socket. In addition to board deflection, other elements need to be considered to define the space needed for the downward board total displacement under load, like the potential interference of through-hole mount component pin tails of the board with a mechanical fixture on the back of the board. NOTES: 1. The heatsink preload must remain below the maximum load limit of the package at all times (Refer to processor datasheet) 2. Board deflection should not exceed motherboard manufacturer specifications. LGA775 Socket Heatsink Loading 80 Thermal and Mechanical Design Guidelines A.2.5.1 Motherboard Stiffening Considerations To protect LGA775 socket solder joint, designers need to drive their mechanical design to: • Allow downward board deflection to put the socket balls in a desirable force state to protect against fatigue failure of socket solder joint (refer to Sections A.2.1, A.2.2, and A.2.3. • Prevent board upward bending during mechanical shock event • Define load paths that keep the dynamic load applied to the package within specifications published in the processor datasheet Limiting board deflection may be appropriate in some situations like: • Board bending during shock • Board creep with high heatsink preload However, the load required to meet the board deflection recommendation (refer to Section A.2.3) with a very stiff board may lead to heatsink preloads exceeding package maximum load specification. For example, such a situation may occur when using a backing plate that is flush with the board in the socket area, and prevents the board to bend underneath the socket. A.3 Heatsink Selection Guidelines Evaluate carefully heatsinks coming with motherboard stiffening devices (like backing plates), and conduct board deflection assessments based on the board deflection metric. Solutions derived from the reference design comply with the reference heatsink preload, for example: • The Boxed Processor • The reference design (D60188-001 and E18764-001) Intel will collaborate with vendors participating in its third party test house program to evaluate third party solutions. Vendor information now is available in Intel® Core™2 Duo Processor Support Components webpage www.intel.com/go/thermal_Core2Duo . § Heatsink Clip Load Metrology Thermal and Mechanical Design Guidelines 81 Appendix B Heatsink Clip Load Metrology B.1 Overview This section describes a procedure for measuring the load applied by the heatsink/clip/fastener assembly on a processor package. This procedure is recommended to verify the preload is within the design target range for a design, and in different situations. For example: • Heatsink preload for the LGA775 socket • Quantify preload degradation under bake conditions. Note: This document reflects the current metrology used by Intel. Intel is continuously exploring new ways to improve metrology. Updates will be provided later as this document is revised as appropriate. B.2 Test Preparation B.2.1 Heatsink Preparation Three load cells are assembled into the base of the heatsink under test, in the area interfacing with the processor Integrated Heat Spreader (IHS), using load cells equivalent to those listed in Section B.2.2. To install the load cells, machine a pocket in the heatsink base, as shown in Figure 7-8 and Figure 7-9. The load cells should be distributed evenly, as close as possible to the pocket walls. Apply wax around the circumference of each load cell and the surface of the pocket around each cell to maintain the load cells in place during the heatsink installation on the processor and motherboard (Refer to Figure 7-9). The depth of the pocket depends on the height of the load cell used for the test. It is necessary that the load cells protrude out of the heatsink base. However, this protrusion should be kept minimal, as it will create additional load by artificially raising the heatsink base. The measurement offset depends on the whole assembly stiffness (i.e. motherboard, clip, fastener, etc.). For example, the reference design clip and fasteners assembly stiffness is around 380 N/mm [2180 lb/in]. In that case, a protrusion of 0.038 mm [0.0015”] will create an extra load of 15 N [3.3 lb]. Figure 7-10 shows an example using the reference design. Note: When optimizing the heatsink pocket depth, the variation of the load cell height should also be taken into account to make sure that all load cells protrude equally from the heatsink base. It may be useful to screen the load cells prior to installation to minimize variation. Heatsink Clip Load Metrology 82 Thermal and Mechanical Design Guidelines Remarks: Alternate Heatsink Sample Preparation As mentioned above, making sure that the load cells have minimum protrusion out of the heatsink base is paramount to meaningful results. An alternate method to make sure that the test setup will measure loads representative of the non-modified design is: • Machine the pocket in the heat sink base to a depth such that the tips of the load cells are just flush with the heat sink base • Then machine back the heatsink base by around 0.25 mm [0.01”], so that the load cell tips protrude beyond the base. Proceeding this way, the original stack height of the heatsink assembly should be preserved. This should not affect the stiffness of the heatsink significantly. Figure 7-8.

Table 7-2. Typical Test Equipment Item Description Part Number (Model) Load cell Notes: 1, 5 Honeywell*-Sensotec* Model 13 subminiature load cells, compression only Select a load range depending on load level being tested. www.sensotec.com AL322BL Data Logger (or scanner) Notes: 2, 3, 4 Vishay* Measurements Group Model 6100 scanner with a 6010A strain card (one card required per channel). Model 6100 NOTES: 1. Select load range depending on expected load level. It is usually better, whenever possible, to operate in the high end of the load cell capability. Check with your load cell vendor for further information. 2. Since the load cells are calibrated in terms of mV/V, a data logger or scanner is required to supply 5 volts DC excitation and read the mV response. An automated model will take the sensitivity calibration of the load cells and convert the mV output into pounds. 3. With the test equipment listed above, it is possible to automate data recording and control with a 6101-PCI card (GPIB) added to the scanner, allowing it to be connected to a PC running LabVIEW* or Vishay's StrainSmart* software. 4. IMPORTANT: In addition to just a zeroing of the force reading at no applied load, it is important to calibrate the load cells against known loads. Load cells tend to drift. Contact your load cell vendor for calibration tools and procedure information. 5. When measuring loads under thermal stress (bake for example), load cell thermal capability must be checked, and the test setup must integrate any hardware used along with the load cell. For example, the Model 13 load cells are temperature compensated up to 71 °C, as long as the compensation package (spliced into the load cell's wiring) is also placed in the temperature chamber. The load cells can handle up to 121 °C (operating), but their uncertainty increases according to 0.02% rdg/°F. B.3 Test Procedure Examples The following sections give two examples of load measurement. However, this is not meant to be used in mechanical shock and vibration testing. Any mechanical device used along with the heatsink attach mechanism will need to be included in the test setup (i.e., back plate, attach to chassis, etc.). Prior to any test, make sure that the load cell has been calibrated against known loads, following load cell vendor’s instructions. Heatsink Clip Load Metrology Thermal and Mechanical Design Guidelines 85 B.3.1 Time-Zero, Room Temperature Preload Measurement 1. Pre-assemble mechanical components on the board as needed prior to mounting the motherboard on an appropriate support fixture that replicate the board attach to a target chassis • For example: standard ATX board should sit on ATX compliant stand-offs. If the attach mechanism includes fixtures on the back side of the board, those must be included, as the goal of the test is to measure the load provided by the actual heatsink mechanism. 2. Install relevant test vehicle (TTV, processor) in the socket 3. Assemble the heatsink reworked with the load cells to motherboard as shown for the reference design example in Figure 7-10, and actuate attach mechanism. 4. Collect continuous load cell data at 1 Hz for the duration of the test. A minimum time to allow the load cell to settle is generally specified by the load vendors (often of order of 3 minutes). The time zero reading should be taken at the end of this settling time. 5. Record the preload measurement (total from all three load cells) at the target time and average the values over 10 seconds around this target time as well, i.e. in the interval , for example over [target time – 5 seconds ; target time + 5 seconds]. B.3.2 Preload Degradation under Bake Conditions This section describes an example of testing for potential clip load degradation under bake conditions. 1. Preheat thermal chamber to target temperature (45 ºC or 85 ºC for example) 2. Repeat time-zero, room temperature preload measurement 3. Place unit into preheated thermal chamber for specified time 4. Record continuous load cell data as follows: • Sample rate = 0.1 Hz for first 3 hrs • Sample rate = 0.01 Hz for the remainder of the bake test 5. Remove assembly from thermal chamber and set into room temperature conditions 6. Record continuous load cell data for next 30 minutes at sample rate of 1 Hz. § Heatsink Clip Load Metrology 86 Thermal and Mechanical Design Guidelines Thermal Interface Management Thermal and Mechanical Design Guidelines 87 Appendix C Thermal Interface Management To optimize a heatsink design, it is important to understand the impact of factors related to the interface between the processor and the heatsink base. Specifically, the bond line thickness, interface material area and interface material thermal conductivity should be managed to realize the most effective thermal solution. C.1 Bond Line Management Any gap between the processor integrated heat spreader (IHS) and the heatsink base degrades thermal solution performance. The larger the gap between the two surfaces, the greater the thermal resistance. The thickness of the gap is determined by the flatness and roughness of both the heatsink base and the integrated heat spreader, plus the thickness of the thermal interface material (for example thermal grease) used between these two surfaces and the clamping force applied by the heatsink attach clip(s). C.2 Interface Material Area The size of the contact area between the processor and the heatsink base will impact the thermal resistance. There is, however, a point of diminishing returns. Unrestrained incremental increases in thermal interface material area do not translate to a measurable improvement in thermal performance. C.3 Interface Material Performance Two factors impact the performance of the interface material between the processor and the heatsink base: • Thermal resistance of the material • Wetting/filling characteristics of the material Thermal resistance is a description of the ability of the thermal interface material to transfer heat from one surface to another. The higher the thermal resistance, the less efficient the interface material is at transferring heat. The thermal resistance of the interface material has a significant impact on the thermal performance of the overall thermal solution. The higher the thermal resistance, the larger the temperature drop is across the interface and the more efficient the thermal solution (heatsink, fan) must be to achieve the desired cooling. The wetting or filling characteristic of the thermal interface material is its ability, under the load applied by the heatsink retention mechanism, to spread and fill the gap between the processor and the heatsink. Since air is an extremely poor thermal conductor, the more completely the interface material fills the gaps, the lower the temperature drops across the interface. In this case, thermal interface material area also becomes significant; the larger the desired thermal interface material area, the higher the force required to spread the thermal interface material. § Thermal Interface Management 88 Thermal and Mechanical Design Guidelines Case Temperature Reference Metrology Thermal and Mechanical Design Guidelines 89 Appendix DCase Temperature Reference Metrology D.1 Objective and Scope This appendix defines a reference procedure for attaching a thermocouple to the IHS of a 775-land LGA package for TC measurement.

Omega Thermocouple Case Temperature Reference Metrology Thermal and Mechanical Design Guidelines 91 D.3 Thermal Calibration and Controls It is recommended that full and routine calibration of temperature measurement equipment be performed before attempting to perform temperature case measurement. Intel recommends checking the meter probe set against known standards. This should be done at 0 ºC (using ice bath or other stable temperature source) and at an elevated temperature, around 80 ºC (using an appropriate temperature source). Wire gauge and length also should be considered as some less expensive measurement systems are heavily impacted by impedance. There are numerous resources available throughout the industry to assist with implementation of proper controls for thermal measurements. NOTES: 1. It is recommended to follow company standard procedures and wear safety items like glasses for cutting the IHS and gloves for chemical handling. 2. Please ask your Intel field sales representative if you need assistance to groove and/or install a thermocouple according to the reference process. D.4 IHS Groove Cut a groove in the package IHS; see the drawings given in Figure 7-12 and Figure 7-13. The groove orientation in Figure 7-12 is toward the IHS notch to allow the thermocouple wire to be routed under the socket lid. This will protect the thermocouple from getting damaged or pinched when removing and installing the heatsink (see Figure 7-37).

Figure 7-14. IHS Groove at 6 o’clock Exit on the 775-LAND LGA Package When the processor is installed in the LGA775 socket, the groove is parallel to the socket load lever, and is toward the IHS notch as shown Figure 7-15. Figure 7-15. IHS Groove at 6 o’clock Exit Orientation Relative to the LGA775 Socket Select a machine shop that is capable of holding drawing specified tolerances. IHS groove geometry is critical for repeatable placement of the thermocouple bead, ensuring precise thermal measurements. The specified dimensions minimize the impact of the groove on the IHS under the socket load. A larger groove may cause the IHS to warp under the socket load such that it does not represent the performance of an ungrooved IHS on production packages. Inspect parts for compliance to specifications before accepting from machine shop. Pin1 indicator IHS Groove Case Temperature Reference Metrology Thermal and Mechanical Design Guidelines 95 D.5 Thermocouple Attach Procedure The procedure to attach a thermocouple with solder takes about 15 minutes to complete. Before proceeding turn on the solder block heater, as it can take up to 30 minutes to reach the target temperature of 153 – 155 °C. Note: To avoid damage to the processor ensure the IHS temperature does not exceed 155 °C. As a complement to the written procedure a video Thermocouple Attach Using Solder – Video CD-ROM is available. D.5.1 Thermocouple Conditioning and Preparation 7. Use a calibrated thermocouple as specified in Sections D.2 and D.3. 8. Under a microscope verify the thermocouple insulation meets the quality requirements. The insulation should be about 1/16 inch (0.062 ± 0.030) from the end of the bead (Figure 7-16). Figure 7-16. Inspection of Insulation on Thermocouple 9. Measure the thermocouple resistance by holding both contacts on the connector on one probe and the tip of thermocouple to the other probe of the DMM (measurement should be about~3.0 ohms for 36-gauge type T thermocouple).
