Thermal/Mechanical Reference Design
2.4.7 Components Overview
2.4.7.1 Heatsink with Captive Screws and Standoffs
The CEK reference heatsink uses snapped-fin technology for its design. It consists of a
copper base and copper fins with Shin-Etsu* G751 thermal grease as the TIM. The
mounting screws and standoffs are also made captive to the heatsink base for ease of
handling and assembly as shown in Figure 2-21 and Figure 2-22 for the 2U+ and 1U
heatsinks, respectively.
Note: Refer to Appendix A for more detailed mechanical drawings of the heatsink.
