2.Remove the PCH heat sink (2).
NOTE: Due to the adhesive quality of the thermal material located between the PCH heat sink and system board, it may be necessary to move the PCH heat sink from side to side to detach it.
The thermal material must be thoroughly cleaned from the surfaces of the PCH heat sink and the PCH each time the PCH heat sink is removed. Replacement thermal material is included with the PCH heat sink and system board spare part kits.
NOTE: The following illustration shows the PCH heat sink replacement thermal material locations. A thermal pad is used on the PCA (1) and the PCH heat sink (2).
Reverse this procedure to install the PCH heat sink.
