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.
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 assem-
bly. 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.
