To install the heatsink (SNK-P0012, optional), do not apply any thermal compound to the heatsink or CPU die - the proper amount has already been applied. Place the heatsink directly on the CPU so that the two mounting holes are aligned with those on the CPU backplate. Make sure the heatsink sits completely fl at on the CPU - if not completely fl at, the space between the two will degrade the heat dissipation function of the heatsink, which may cause the processor to overheat. Screw in the two screws until just snug (do not fully tighten), then fi nish by fully tightening both screws (see Figure 5-1).
Repeat these steps to install the second heatsink to CPU #2.
