Xserve (Late 2006) Thermal Grease Kit Instructions
Important: Each heat sink is connected to the main logic board by a small 2-pin thermal
sensor cable. Be careful not to pull on the wire as you lift each heat sink enough to
disconnect the cable from the main logic board. It’s easier to reach the sensor connectors on
the logic board if you start with the right heat sink near the DIMM slots (CPU A).
Slowly lift the heat sink off the processor just far enough that you can reach the sensor cable
connector. You might feel some resistance from the thermal grease that binds the heat sink
to the processor.
Pull on the connector, not the wires, to disconnect the sensor cable from the main logic
board.
Lift the heat sink straight up and out of the enclosure.
Repeat steps 1 through 4 for the left processor (CPU B) heat sink.
