1. Do not apply any thermal grease to
the heatsink or the CPU die because
the required amount has already been
applied.
2. Place the heatsink on top of the
CPU so that the four mounting holes
are aligned with those on the retention
mechanism.
3. Install two diagonal screws (ie the
#1 and the #2 screws) and tighten
them until just snug (-do not fully
tighten the screws to avoid possible
damage to the CPU.)
4. Finish the installation by fully tight-
ening all four screws.
