NOTE: 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 processor (1) and the heat sink
section (2) that services it.
