2. The following illustration shows the replacement thermal material locations. The thermal material must
be thoroughly cleaned from the surfaces of the heat sink and the system board components each time
the heat sink is removed. Replacement thermal material is included with the heat sink and system board
spare part kits.
Thermal paste is used on the system board component (1) and on the heat sink area (2) that services it.
Reverse this procedure to install the heat sink.
