Processor Heatsink Module (PHM)
After you have made a processor package assembly by following the instructions on the
previous page, please follow the steps below to mount the processor package assembly onto
the heatsink to create the Processor Heatsink Module (PHM).
1. Locate "1" on the heatsink label and the triangular corner next to it on the heatsink.
With your index finger pressing against the screw at this triangular corner, carefully hold
and turn the heatsink upside down with the thermal-grease side facing up. Remove the
protective thermal film if present, and apply the proper amount of the thermal grease
as needed. (Skip this step if you have a new heatsink because the necessary thermal
grease is pre-applied in the factory.)
2. Holding the processor package assembly at the center edge, turn it upside down. With
the thermal-grease side facing up, locate the hollow triangle located at the corner of the
processor carrier assembly ("a" in the graphic). Note a larger hole and plastic mounting
clicks located next to the hollow triangle. Also locate another set of mounting clicks and
a larger hole at the diagonal corner of the same (reverse) side of the processor carrier
assembly ("b" in the graphic).
3. With the back of heatsink and the reverse side of the processor package assembly
facing up, align the triangular corner on the heatsink ("A" in the graphic) against the
mounting clips next to the hollow triangle ("a") on the processor package assembly.
4. Also align the triangular corner ("B") at the diagonal side of the heatsink with the
corresponding clips on the processor package assembly ("b").
5. Once the mounting clips on the processor package assembly are properly aligned with
the corresponding holes on the back of heatsink, securely attach the heatsink to the
processor package assembly by snapping the mounting clips at the proper places on the
heatsink to create the processor heatsink module (PHM).
