To apply the thermal grease compound: 1. Use a clean cloth dipped in rubbing alcohol to clean the contact surface on the heat sink and 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 integrated heat spreader on the processor in one of the following patterns to insure even distribution. CAUTION: HP recommends using Shin-Etsu X-23-7783D thermal grease compound for your ProLiant server. Apply the grease to the top of the processor in either a 5 "Dot" or "S" shaped pattern. Ensure even distribution. Figure 40 The bottom of the heat sink 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 heat sink to draw out heat. Installing the heat sink 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.

2.
Apply the thermal grease compound to the integrated heat spreader on the processor in one of
the following patterns to insure even distribution.
CAUTION:

The bottom of the heat sink
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 heat sink to draw out heat. Installing the heat sink 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.
