Hardware Installation

Installing the Fan and Heat Sink

The CPU must be kept cool by using a CPU fan with heat sink. Without sufﬁ cient

air circulation across the CPU and heat sink, the CPU will overheat damaging both

the CPU and system board.

Note:

A boxed Intel

processor already includes the CPU fan and heat sink as-

sembly. If your CPU was purchased separately, make sure to only use

Intel

-certiﬁ ed fan and heat sink.

1. Before you install the fan / heat sink, you must apply a thermal paste onto

the top of the CPU. The thermal paste is usually supplied when you purchase

the fan / heat sink assembly. Do not spread the paste all over the surface.

When you later place the heat sink on top of the CPU, the compound will dis-

perse evenly.

Some heat sinks come with a patch of pre-applied thermal paste. Do not ap-

ply thermal paste if the fan / heat sink already has a patch of thermal paste

on its underside. Peel the strip that covers the paste before you place the fan

/ heat sink on top of the CPU.

2. Place the heat sink on top

of the CPU. The 4 push-

pins around the heat sink,

which are used to secure

the heat sink onto the sys-

tem board, must match the

4 mounting holes around

the socket.

3. Orient the heat sink such

that the CPU fan’s cable is

nearest the CPU fan con-

nector.
