Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air cir-
culation 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 assembly.
®
If your CPU was purchased separately, make sure to only use Intel
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 disperse evenly.
Some heat sinks come with a patch of pre-applied thermal paste. Do not apply 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 screw
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.

diagonally across the heat sink.
Perform the same procedure
for the other screws.
