Remove the fan and heat sink:
1. Turn the system board upside down, with the fan toward you.
NOTE: Steps 2 through 5 apply only to computer models equipped with a graphics subsystem
with discrete memory. See steps 6 through 8 for fan and heat sink removal information for
computer models equipped with a graphics subsystem with UMA memory.
2. Disconnect the fan cable (1) from the system board.
3. Loosen the captive screws (2) that secure the fan and heat sink to the system board. (Computer
models equipped with an AMD processor have three captive screws. Computer models equipped
with an Intel processor have four captive screws.)
4. Remove the three Phillips PM2.5×6.0 screws (3) that secure the fan and heat sink to the
system board.
NOTE: Due to the adhesive quality of the thermal material located between the heat sink and
system board components, it may be necessary to move the heat sink from side to side to
detach it.
