Installation of the Heatsink
1. Locate the CPU Fan on the moth-
erboard. (Refer to the layout on the
right for the CPU Fan location.)
2. Position the heatsink in such a
way that the heatsink fan wires are
closest to the CPU fan and are not
interfered with other components.
3. Inspect the CPU Fan wires to
make sure that the wires are routed
through the bottom of the heatsink.
4. Remove the thin layer of the
protective fi lm from the copper core of
the heatsink.
(*Warning: CPU overheat may occur
if the protective fi lm is not removed
from the heatsink.)
5. Apply the proper amount of thermal
grease on the CPU. (*Note: if your
heatsink came with a thermal pad,
please ignore this step.)
6. If necessary, rearrange the wires
to make sure that the wires are not
pinched between the heatsink and the
CPU. Also make sure to keep clear-
ance between the fan wires and the
fi ns of the heatsink.
7. Align the four heatsink fasten-
ers with the mounting holes on the
motherboard. Gently push the pairs of
diagonal fasteners (#1 & #2, and #3
& #4) into the mounting holes until
you hear a click. (*Note: Make sure to
orient each fastener in a way that the
narrow end of the groove is pointing
outward.)
