3.6.1Installing the Heatsink and Fan

The Intel® Pentium® 4 478 / Northwood Processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. The Intel Pentium 4 478 / Northwood Processor includes the heatsink, fan, and retention mechanism. If a CPU is purchased separately, only use an Intel certified heatsink and fan.

Step 1: Mount the Heatsink

Place the heatsink on top of the installed CPU. Make sure that the heatsink fits properly on the retention module base. Note that the retention module base is already installed on the motherboard.

WARNING! Be sure that there is sufficient air circulation across the processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard.

NOTE: If using a rectangular heatsink, use a model with fin-ends that project and terminate on the longer side of the unit, not on the shorter side.
