CPU Fan/Heatsink Installation
When the CPU fan/heatsink installation procedures presented
here are inconsistent with the installation procedures included with
the CPU fan and heatsink package, follow the latter.
To install the CPU fan/heatsink:
1. Attach the backplate included with the fan/heatsink to
the bottom side of the SBC. If necessary, remove the
paper strip(s) from the self-adhesive pads to secure the
backplate to the SBC.
2. Remove the cover or plastic protector from the CPU-side
of the heatsink if necessary. The heatsink may have a
thermal interface material pre-applied. If not, a packet of
thermal grease will be supplied with the heatsink. Apply
thermal grease evenly on top of the installed CPU if
required.
3. Carefully lower the CPU fan/heatsink onto the CPU and
align the captive screws with the mounting holes of the
backplate. Ensure the fan cable is on the side closest to
the fan connector. Begin threading each screw into the
backplate, then gradually tighten the screws in a criss-
cross pattern until they are fully secured (see diagram
below).
CAUTION:
Fully tightening a screw at one corner before beginning to
tighten the other screws may cause uneven pressure to be
applied to the CPU and damage the component and/or SBC.
