Assembling the Processor Heatsink Module (PHM)
After creating the processor package assembly, mount it onto the heatsink to create the processor
heatsink module (PHM).
1.
On the heatsink label, locate “1” and the corner next to it. Turn the heatsink upside down with
the thermal grease side facing up, keeping track of the “1” corner.
2.
Remove the protective thermal film if present. If this is a new heatsink, the necessary thermal
grease has been pre-applied in the factory. If the heatsink is not new, apply the proper amount of
thermal grease.
3.
In the plastic processor clip, locate the hollow triangle at the corner (“a” in the drawing below)
next to a hole and plastic mounting clips. There is a similar hole and mounting clips at the
diagonal corner of the processor clip (“b” in the drawing).
4.
With the underside of the heatsink and the underside of the processor package facing up, align
the “1” corner on the heatsink (“A” in the drawing) against the mounting clips next to the hollow
triangle (“a”) on the processor package.
5.
Also align the corner (“B”) at the diagonal side of the heatsink with the corresponding clips on the
processor package (“b”).
6.
Once aligned, press the processor package assembly onto the heatsink until the mounting clips
(at a, b, c, and d) snap into place.
