Figure 137: Removing the performance heat sink
▶ Loosen the four captive screws on the heat sink in a crossover pattern (1-4).
▶ Carefully twist the heat sink back and forth to detach it from the CPU.
This may be necessary due to the adhesive quality of the thermal
paste located between the heat sink and CPU.
CAUTION
▶
Pay special attention not to damage any system board
components surrounding the CPU socket.
▶ Lift the heat sink out of the chassis.
▶ Clean residual thermal paste from the CPU surface using a lint-free cloth
and store the CPU in a save place.
