Installing a Passive CPU Heatsink

1.Do not apply any thermal grease to the heatsink or the CPU die -- the required amount has already been applied.

2.Place the heatsink directly on top of the CPU so that the heat sink screws are aligned with the mounting holes on the back plate.

3.Make sure the screwdriver torgue setting is no more than 5.0 Kgf-cm (4.3 lbf- in) and keep the heat sink direction vertical.

4.Tighten each screw a few turns at a time while alternating between the two until fully tightened.
