✎
The thermal material must be thoroughly cleaned from the surfaces of the heat sink and the system board each time
the heat sink 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.
Replacement thermal material is included with all system board, heat sink, and processor spare part kits.
✎
When replacing the heat sink, be sure to remove the fan from the defective heat sink and install it on the
replacement heat sink. See “Fan” on page 4-32 for fan removal instructions.
Reverse this procedure to install the heat sink.
