2.3.2 Installing the CPU heatsink and fan
The Intel Xeon 5500 series processors require a specially designed heatsink to
ensure optimum thermal condition and performance.
• Ensure that you use qualified heatsink assembly only.
• Ensure that you have applied the thermal interface material to the top of the
CPU before installing the heatsink and fan.
Follow these steps to install the CPU heatsink and fan.
1. Orient and place the heatsink on top of the installed CPU, ensuring that the
screw holes are matched with the heatsink standoffs.
2. Use a Phillips screwdriver to tighten the four heatsink screws in a diagonal
sequence.
Ensure that the heatsink is not skewed or tilted, otherwise the CPU will overheat.
