CompactPCI* Reference Heatsink

Intel has also developed a reference thermal solution compatible with the CompactPCI* 

form factor. The reference solution was developed assuming a maximum ambient 

temperature of 67 °C with a minimum volumetric airflow rate of 10 CFM through each 

slot. Assuming these boundary conditions are met, the reference thermal solution 

meets the thermal specifications for Intel

 5100 Memory Controller Hub Chipset. 

6.2.1

Component Overview

The CompactPCI* reference heatsink is an extruded aluminum heatsink and does 

not

 

share the same volumetric footprint as the AdvancedTCA* reference heatsink. Full 

mechanical drawings of the thermal solution assembly, full mechanical drawings, 

volumetric footprint, and the heatsink clip are provided in 

Appendix A

. It uses the same 

spring clip retention and Honeywell* PCM45F Thermal Interface Material (TIM) as the 

AdvancedTCA* reference solution.

Figure 21

 shows the isometric view of the CompactPCI* reference heatsink.
