2. Inspect the thermal patch. Replace the patch if it is damaged:
a. Ensure that you are grounded with a static-dissipating wrist strap.
b. Remove the damaged patch. If you are reinstalling a heatsink on a processor, use a lint-free
cloth to remove any thermal material remaining on top of the processor chip.
c. To install a new thermal patch, peel off the backing, and place the patch in the area marked
at the center of the heatsink.
CAUTION
Heatsinks are not reusable unless the thermal patch is replaced
each time
the
heat sink is removed, even if it is temporarily removed and reinstalled on the
same processor.
3. Install the heatsink:
a. Orient the heatsink with the tool latch facing left. Then lower the heatsink squarely onto the
processor.
CAUTION
Ensure the heatsink is seated properly on the processor. If the heatsink is
offset, there will be insufficient thermal contact with the processor, which may
result in overheating, data corruption, and permanent damage to the processor.
b. Hold the heatsink steady with one hand and press the hook latch down to connect it to the
tab. Then insert a flat-head screwdriver into the tool latch and press the latch down to
connect it to the tab.
4. Replace the air flow guide.
