Installing the Heatsink

After installing a new processor, you need to install a heatsink on top of the
processor. The thermal patch on the bottom of the heatsink provides thermal
bonding between the two components. The patch must be replaced if the heatsink
is removed (even temporarily) from the processor.
1. Remove the heatsink from the shipping container.
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
3. Install the heatsink:
a. Orient the heatsink with the tool latch facing left, as shown in
Figure 6-4 and Figure 6-5. Then lower the heatsink squarely onto the
processor.
CAUTION
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.
See Figure 6-5.
4. Replace the air flow guide. Refer to Chapter 2, "Opening and Closing the HP
Netserver."
Installing an Additional Processor
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.
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.
