1.6.2 Installing the CPU Heatsink and Fan
The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.
z
Install the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
z
When you buy a boxed Intel® Pentium® 4 processor, the
package includes the CPU fan and heatsink assembly. If you buy
a CPU separately, make sure that you use only Intel®
‑
certified
multi
‑
directional heatsink and fan.
z
Your Intel® Pentium® 4 LGA775 heatsink and fan assembly
comes in a push-pin design and requires no tool to install.
If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied Thermal Interface Material to the
CPU heatsink or CPU before you install the heatsink and fan
assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of
the installed CPU, making
sure that the four fasteners
match the holes on the
motherboard.
Orient the heatsink
and fan assembly
such that the CPU fan
cable is closest to the
CPU fan connector.
Make sure each fastener is oriented as shown, with the narrow groove
directed outward.
