Installing the Heatsink and Fan

The system board may come with a heatsink or a cooler (heatsink with fan), including four
stand-offs and four stand-off screws to secure the board and heatsink onto the chassis. The
assembly is expected to be installed in the manners as illustrated below.
Note:
The standard package includes a fanless heatsink. The heatsink with fan is an op-
tional item available upon request.

Stand-offs
Please make sure the contacting sides of the
heat spreader and the module are correct —
the CPU side of the module shall be facing the
interface metal side and legs of the heat sink.
Rotate horozontally so the interface metal sits
right on top of the CPU, and align the screw
holes on the heatsink to those on the module.
Remove any plastic cover on the interface
metal and apply thermal paste/adhesive if it is
required.
Connect the CPU fan cable to the CPU fan con-
nector on the top side of the module. This step
can be omitted if it is a fanless heatsink.
Screw the stand-offs onto the chassis. This
step can be omitted if there exist pre-installed
stand-offs on the chassis.
