Creating the Processor Heatsink Module (PHM)
After creating the processor carrier assembly, please follow the instructions below to mount
the processor carrier into the heatsink to form the processor heatsink module (PHM).
Note: If this is a new heatsink, the thermal grease has been pre-applied on the un-
derside. Otherwise, apply the proper amount of thermal grease.
1. Turn the heatsink over with the thermal grease, which is on the reverse side of the
heatsink, facing up. Pay attention to the two triangle cutouts (A, B) located at the
diagonal corners of the heatsink as shown in the drawing below.
2. Hold the processor carrier assembly top side (with thermal grease) facing up, and locate
the triangle on the CPU and the triangle on the carrier. (Triangle indicates Pin 1.)
3. Using Pin 1 as a guide, turn the processor carrier assembly over with the gold contacts
facing up. Locate Pin 1 (A) on the processor and Pin 1 (a) on the processor carrier
assembly "a".
4. Align the corner marked "a" on the processor carrier assembly against the triangle
cutout "A" on the heatsink, and align the corners marked "b", "c", "d" on processor
assembly against the corners marked "B", "C", "D" on the heatsinks
5. Once they are properly aligned, place the corner marked "a" on the processor carrier
assembly into the corner of the heatsink marked "A". Repeat the same step to place the
corners marked "b", "c", "d" on the processor carrier assembly into the corners of the
heatsink marked "B", "C", "D" making sure that all plastic clips are properly attached to
the heatsink.
