distribution.
Figure 16 Applying grease
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.
To install the heat sink:
CAUTION: To prevent overheating or a possible system crash, use only a heat sink model specified
for the HP ProLiant SL160z G6 server.
Put the heat sink frame on the CPU socket.
1.
Properly align the heat sink mounting pins to the system board mounting holes.
2.
Tighten the mounting pins clockwise to secure the heat sink connection to the system board.
3.
CAUTION: To prevent the heat sink from tilting to one side during installation and removal
procedures, use a diagonally opposite pattern (an "X" pattern) when loosening and tightening the
two spring-loaded screws. Do not over tighten the heat sink's spring-loaded screws to prevent them
from breaking off. A maximum torque of 4 in-Ib is set for the system.
