Installing A Microprocessor And Heat Sink - IBM LS42 - BladeCenter - 7902 Service Manual

7. Remove the heat sink.
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, you must replace the
heat sink.
a. Loosen the captive screws on one side of the heat sink to break the seal
with the microprocessor.

packaging instructions, and use any packaging materials for shipping that are
supplied to you.
