2.4.3 Installing the heatsink
Follow these steps to install the CPU heatsink.
1. Carefully place the heatsink on top
of the installed CPU. The heatsink
fits in only one orientation. Take
note of the heatsink placement as
shown (ASUS logo facing the rear
panel).
2. Hold down the heatsink lightly and
twist each of the four screws with
a flat screw driver just enough to
attach the heatsink to the
motherboard.
3. When the four screws are
attached, tighten them one by one
to completely secure the heatsink.
