Remove the fan/heat sink assembly:
1. Disconnect the fan cable from the system board.
2. Turn the system board upside down with the front toward you.
3. Loosen the six Phillips PM2.5×7.0 captive screws (1) that secure the fan/heat sink assembly to the
base enclosure in the 1, 2, 3, 4, 5, 6 sequence stamped into the fan/heat sink assembly.
4. Remove the fan/heat sink assembly (2).
NOTE: Due to the adhesive quality of the thermal material located between the processor heat
sink and system board components, it may be necessary to move the processor heat sink from
side to side to detach it.
NOTE: The thermal material must be thoroughly cleaned from the surfaces of the heat sink (1) and
(2), the processor (3), and graphics system component (4) each time the heat sink is removed.
Replacement thermal material is included with all system board and fan/heat sink assembly spare part
kits.
