Thermal Design Guide for Socket F (1207) Processors
Depending on the system features and layout, more space around the socket may be available for the 
thermal solution than is shown in Figure 2 on page 15. This space permits heat sink designs with 
better thermal performance.
Appendix A on page 37 shows a complete, detailed set of keep-out drawings for the AMD PIB 
thermal solution for socket F (1207). 
3.2
Thermal Solution Design Requirements
Table 2 provides the design-target specifications that must be met for the processor to operate reliably 
in a typical platform using the AMD PIB thermal solution for socket F (1207) processors.
3.3
Sample Heat Sinks and Attachment Methods
The heat sink, fan, mounting spring clip, and thermal interface material used for the AMD PIB 
thermal solution for socket F (1207) processors are the same as the heat sink, fan, mounting spring 
clip, and thermal interface material used for systems based on the socket 940 processor. 
The backplate and retention frame are different from those used in the socket 940 processor. The 
EMC shield implemented in the socket 940-based systems is not recommended for AMD PIB thermal 
solutions for socket F (1207)  processors.

Notes:
1. This is the thermal resistance required for dual-core, 90-nm socket F (1207) processors. The thermal resistance 
requirement may vary depending on the product OPN. The user should consult the processor data sheet for the 
thermal requirements specific to the part.
2. Heat sinks weighing up to 450 g can be attached to the motherboard. Heat sinks weighing over 450 g should be tied 
directly to the chassis for reliable shock and vibration performance.
