socket.
Step 11. If you are reinstalling a heat sink that was removed from the blade server, complete the following
steps:
Attention:
• Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material
will contaminate it. If the thermal material on the microprocessor or heat sink becomes
contaminated, contact your service technician.
• Do not touch exposed pins of the microprocessor socket.
a.
Make sure that the thermal material is still on the bottom of the heat sink and on the top of the
microprocessor.
b.
Align and place the heat sink on top of the microprocessor in the retention bracket, thermal

Repeat until the screws are tight. Do not overtighten the screws by using excessive force. If
you are using a torque wrench, tighten the screws to 1.13 ± 0.13 Newton-meters (Nm) (10 ±
0.15 in-lbs).
Step 12. If you are installing a new heat sink, complete the following steps:
Attention:
• Do not set down the heat sink after you remove the plastic cover.
• Do not touch the thermal material on the bottom of the heat sink. Touching the thermal material
