Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circula-
tion 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
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 spring screws around the heat sink, which
are used to secure the heat sink onto the system board, must match the 4 mounting
holes around the socket.
3. Orient the heat sink so that the CPU fan's cable is nearest the CPU fan connector.
