Creating the PHM (4U Heatsink)
After creating the processor carrier assembly, please follow the instructions below to mount
the processor carrier assembly into the heatsink to form the 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 bottom side of the
heatsink, facing up. Pay attention to the two triangle cutouts (marked A and B) located
at the diagonal corners of the heatsink as shown below.
2. Hold the processor carrier assembly with component side 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 the triangle cutout (marked A) on the heatsink and the corner (marked
a) on the processor carrier assembly.
4. Align the corner (marked a) on the processor carrier assembly against the triangle
cutout (marked A) on the heatsink, and align the corners (marked b, c, d) on the
processor carrier assembly against the corners (marked B, C, D) on the heatsink.
5. Once they are properly aligned, place the corners (marked a, b, c, d) on the processor
carrier assembly into the corners of the heatsink (marked A, B, C, D), making sure that
all plastic clips are properly attached to the heatsink.
