2.3.3 Installing the CPU heatsink and fan assembly
The AMD ® Opteron™ 4100 series processors require a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.
• Ensure to use qualified heatsink and fan assembly only.
• Ensure that you have applied the thermal grease to the top of the CPU
before installing the heatsink and fan assembly.
To install the CPU heatsink and fan assembly:
1. Ensure that the retension module base is installed on the motherboard. Refer
to the previous section for the retension module installation.
2. Place the heatsink and fan assembly on top of the installed CPU, ensuring
that the heatsink fits properly on the retention module base.
Your boxed CPU heatsink and fan assembly should come with installation
instructions for the CPU, heatsink, and the retention mechanism. If the
instructions in this section do not match the CPU documentation, follow the
latter.
If you purchased a separate CPU heatsink and fan assembly, ensure that a
Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.
