Do not disturb or contaminate the thermal material on the bottom of the new
heat sink. Doing so damages its heat-conducting capability and exposes the
new microprocessor to overheating.
v
If you need to remove the heat sink after installing it, note that the thermal
material may have formed a strong bond between the heat sink and the
microprocessor. Do not force the heat sink and microprocessor apart; doing
so can damage the microprocessor pins. Loosening one captive screw fully
before loosening the other captive screw helps break the bond between the
components without damaging them.
7. Remove the heat sink from its package and remove the cover from the bottom
of the heat sink. Ensure that the thermal material is still on the bottom of the
heat sink and position the heat sink on top of the microprocessor. Press firmly
on the captive screws and tighten them, alternating between screws until they
