NOTE: Due to the adhesive quality of the thermal material located between the heat sink and the system board components, it may be necessary to move the heat sink from side to side to detach it. NOTE: The thermal material must be thoroughly cleaned from the surfaces of the system board (1) and the heat sink (2) each time the heat sink is removed. Replacement thermal material is included with the heat sink and system board spare part kits. Component replacement procedures 55
