Installing the 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. Apply a thin layer of thermal paste on top of the heat sink. 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.
2. Place the heat sink assembly on top of the CPU. The 4 screws around the heat sink must
match the mounting holes. We strongly recommend using this type of heat sink assembly
because it provides adequate cooling to the components 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.
