2.3.3 Installing the heatsink and fan
The Intel ® Pentium ® 4 Processor requires a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.
Retention Module Base
CPU Heatsink
Follow these steps to install the CPU heatsink and fan.
1. Place the heatsink on top of the installed CPU, making sure that the
heatsink fits properly on the retention module base.
Your boxed Intel ® Pentium ® 4 processor package 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.
When you buy a boxed Intel ® Pentium ® 4 processor, the package
includes the heatsink, fan, and retention mechanism.
In case you buy a CPU separately, make sure that you use only
Intel
® -certified heatsink and fan.
The retention module base is already installed on the motherboard
upon purchase.
You do not have to remove the retention module base when installing
the CPU or installing other motherboard components.
