CAUTION: To allow heatsink to draw as much heat as possible from the processor base, there must
be good contact between the heatsink base and the top of the processor. To ensure good contact,
you must apply thermal interface material.
To apply the thermal grease compound:
1. Use a clean cloth dipped in rubbing alcohol to clean the contact surface on the heatsink and on the new
processor. Wipe the contact surfaces several times to make sure that no particles or dust contaminants are
evident.
2. Apply the thermal grease compound to the CPU contact surface.
CAUTION: HP recommends using Shin-Etsu X-23-7783D thermal grease compound for your ProLiant
server.
3. Apply all the grease to the top of the processor in one of the following patterns to insure even distribution.

CAUTION: Never touch the bottom of the processor; any contaminant could prevent the mounting
pads from making contact with the socket.
CAUTION: Applying too much grease creates a gap between the contact surfaces, significantly
reducing the ability of the heatsink to draw out heat. Installing the heatsink with excessive grease
can also cause the grease to spread over the processor pins or the system board base, which can
cause electrical shorts that damage the system.
To install the new processor:
1. Insert the processor into the socket, using the key on the processor.
2. Engage the retention plate.
3. Engage the load lever.
CAUTION: With the load lever and the retention plate disengaged, hold the processor by its edges
and align it over the empty processor socket. Make sure that you properly align the processor with
the orientation notch on the socket.
