Processor Carrier Assembly
The Processor Heatsink Module (PHM)
After creating the processor carrier assembly, mount the heatsink onto the carrier assembly
to form the processor heatsink module (PHM).
Note:
If this is a new heatsink, the thermal grease has been pre-applied. Otherwise, apply
the proper amount of thermal grease to the underside of the heatsink.
1. Turn the heatsink over with the thermal grease facing up. Note the two triangle cutouts
(A, B) located at the diagonal corners of the heatsink as shown in the drawing below.
2.
On the processor carrier assembly, find pin 1, as noted by the triangles. Hold the
processor carrier assembly over so that the gold LGA is facing up.
3. Align clip "a" (pin 1) on the carrier assembly with the triangular cutout A on the heatsink
and b, c, d on the carrier assembly with B, C, D on the heatsink.
4. Push the carrier assembly onto the heatsink, making sure that all four clips on each
corner are properly secured.
