Warning !

CPU Heatsink Installation Procedure
(For Supermicro SuperServer 2U Systems)

Due to the fact that adequate air flow and proper thermal control are very critical in maintaining 1U
system's stability and performance, it is imperative that the proper installation procedures listed
below be followed in order to maximize system performance. This is especially critical for 2U dual
Xeon processor server solutions.

1) Only those CPU heatsinks that are provided by Supermicro should be used.

2) Apply a small amount of silicon compound on the CPU's die.

3) Place the CPU heatsink on top of the CPU.

4) Attach the heatsink clips to the heatsink retention pieces, one on each
side of the heatsink as shown in the diagram at right.

5) The three tabs on each heatsink retention pieces should completely
protrude though the corresponding holes on the heatsink clips.

To protect the system and components, it is essential that you reinstall the top panel after you have finished working on the system.
