X CPU
The system board is embedded with a AMD® EPYC™ Embedded CPU.
Installing the CPU 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.
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.
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.
