Warning !

CPU Heat Sink Installation Procedures
(For Supermicro SuperServer 1U Systems)

clip

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 1U Dual Processor Servers with speeds of 1 GHz and above.

1) Only those CPU heat sinks 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 heat sink on top of the CPU.

4) Place the heat sink spring on top of the CPU heat sink and secure the clip of 
the spring into its notch. (Make sure the clip position is the same as the  
picture shown above.)

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