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.
1. On the solder side of the board, match the retention module base to the mounting holes
around the CPU socket.

2. Turn to the component side of the board making sure the retention module base is posi-
tioned and fitted properly under the board.
3. Apply a thin layer of thermal paste on top of the CPU. Do not spread the paste all over
the surface. When you later place the heat sink on top, the compound will disperse evenly.
Note:
• Use only certified fan and heat sink.
• Your 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 dif-
fers from the one in this section, please follow the installation guide in the package.
4. Place the fan / heat sink assembly on top of the CPU. The 4 screws around the heat sink
must match the screw holes of the retention module base. We strongly recommend using
this type of fan / heat sink assembly because it provides adequate cooling to the compo-
nents of the system board.
Turn each Phillips head screw half way down first to initially stabilize the heat sink onto
the board, then finally tighten each screw.
Important:
Do not turn the first screw all the way down followed by the next and so on. This is
to avoid imbalance which might cause cracks or fractures to the CPU and/or heat sink
assembly.
