Installing The Fan And Heat Sink - DFI AR100-DR User Manual

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.
The fan / heat sink assembly must provide airflow adequate to ensure appropri-
ate internal temperature and cooling of the components in the system. Failure
to use the appropriate cooling system may result in reduced performance or, in
some instances, damage to the system board.
Note:
• Use only certified fan and heat sink.
• The fan and heat sink package usually contains the fan and heat sink
assembly, and an installation guide. If the installation procedure in
the installation guide differs from the one in this section, please follow
the installation guide in the package.
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 CPU or fan heat sink assembly. Do not spread the paste all over the sur-
face. When you later place the heat sink on top of the CPU, the compound
will disperse evenly.
Do not apply the 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. The system board comes
with the retention module
base already installed.
