Removing processor heat sinks
I
The following procedure is identical for the heat sinks of both CPUs.
Figure 81: Removing the processor heat sink (A)
Ê
Loosen the four captive screws (combihexagon) on the heat sink in the
following pattern: (4)->(3)->(2)->(1).
I
Keep pressing on the heatsink to avoid tilting until the screws (1) and
(2) are removed.
Ê
Carefully turn the heat sink back and forth to detach it from the processor.
I
This may be necessary due to the adhesive quality of the thermal
paste located between the heat sink and processor.
V
CAUTION!
Pay special attention not to damage any system board components
surrounding the processor socket.
Ê
Lift the heat sink out of the chassis.
Ê
Thoroughly clean residual thermal paste from the surface of the heat sink
and the processor using a lint-free cloth.
