Hardware Installation
Installing the Fan and Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient
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
® -certified 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.
