The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink assembly, the system board, and the processor each time the fan/heat sink assembly is removed:

Thermal paste is used on the processor 1 and the heat sink section 2 that services it.

Thermal pads are used on the Northbridge chip 3 and the heat sink section 4 that services it.

Thermal pads are used on various other system board components 5 and 7, and the sections of the heat sink 6 and 8.

Replacement thermal material is included with all fan/heat sink assembly, system board, and processor spare part kits.

Reverse this procedure to install the fan/heat sink assembly.
