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 2-13 and Figure 2-14 for the 2U+ and 1U heatsinks, respectively.
