Installing the CPU 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.
Before you place the heat sink on the CPU, you must apply a thermal paste onto the top of the
heat sink. The thermal paste is usually supplied when you purchase the fan with heat sink as-
sembly. Do not spread the paste all over the surface. When you later place the CPU on top of
the heat sink, 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 with heat sink already has a patch of thermal paste on its underside. Peel the strip that
covers the paste before you place the CPU on top of the heat sink.

CPU
The system board is embedded with a AMD® EPYC™ Embedded CPU.
There are 4 screw holes around the CPU for the heat sink to be mounted.
Align the 4 screw holes and tighten the heat sink up by inserting screws, DO remember to con-
nect the fan cable on the board.
