cable. Lifting the heat sink too quickly can damage the cable or connector. Because of
the tight thermal bond between the processor and heat sink, be especially cautious to
initially lift the heat sink no more than one centimeter (1 cm) off the processor. Do not
pull on the cable as you lift each heat sink enough to disconnect the cable from the
logic board.
Slowly raise the heat sink off the processor just far enough that you can reach the sensor
cable connector.
Pull on the connector, not the cable, to disconnect the sensor cable from the logic board.

Lift the heat sink straight up and out of the enclosure.

grease from the underside of the heat sink. Save the alcohol wipe package for later.
Note: You will need to clean off the old thermal grease from the bottom of each heat sink
and the top of each processor and apply new thermal grease to the processors when you are
reassembling the Xserve. For more information, see “Replacing the Processor Heat Sinks.””
