4.Remove the processor fan/heat sink assembly (4).
NOTE: Due to the adhesive quality of the thermal material located between the processor fan/ heat sink assembly and system board components, it may be necessary to move the processor fan/heat sink assembly from side to side to detach it.
NOTE: The thermal material must be thoroughly cleaned from the surfaces of the processor fan/heat sink assembly and the system board each time the processor fan/heat sink assembly is removed. Thermal paste is used on the processor (1) and the processor fan/heat sink assembly section (2) that services it. Replacement thermal material is included with all system board, processor, and fan/heat sink assembly spare part kits.
Reverse this procedure to install the fan.
