HP ProLiant DL170e G6 Server Installation Sheet

1. Put the heat sink frame on the processor socket. (Step 1 in
Figure 21)
2. Properly align the heat sink spring-loaded screws to the system
board mounting holes. (Step 2 in Figure 21)
3. Tighten the spring-loaded screws clockwise to secure the heat
sink connection to the system board. (Step 3 in Figure 21)
Figure 21 Installing the Heat Sink Assembly
CAUTION: Be sure that the heat sink sits squarely on the
processor, or overheating and damage to the processor
may occur.
CAUTION: To prevent the heat sink from tilting to one
side during installation/removal, turn each screw a
couple of turns, alternatively between both of them, and
then apply the final torque. Do not over tighten the spring
loaded screws to prevent them from breaking off. A
maximum torque of 4.5 inch-lb is set for each screw.
IMPORTANT: If the heat sink has been removed for any
reason, it is critical that you apply more thermal interface
material to the integrated heat spreader on the processor
to ensure proper thermal bonding between the processor
and the heat sink. Clean the contact surface of both the
processor and heat sink with an alcohol pad, then re-
apply an HP-approved thermal interface material before
reinstalling the processor. Use a pattern of five dots when
applying the thermal interface material—one dot in the
center, and one dot at each corner.
