4. Peel off the protective film from the
retention module. This will expose the
adhesive sponge.
5. Face the retention module with the side
of adhesive sponge toward the bottom
side of the motherboard. Align the four
screw holes from the retention module
through the motherboard.
6. Peel off the protecting film that was
originally attached to the bottom of CPU
heatsink. This film prevents the thermal
paste from being touched by anything
but the CPU die, and so it has to be
removed to increase the contact with
the CPU die after having installed the
heatsink.
Forgetting to do so may cause the
CPU over-heated and eventually
ruined!
※ Watch out for the integrity and usability of the thermal paste each time when
re-installing the heatsink. Applying a few drop of thermal paste will help to
increase the contact in between the CPU die and heatsink, especially when
having installed and removed the heatsink for several times.
