Apple Xserve Intel (Late 2006) DIY Procedure for Heatsink - Manual (Page 5)

Xserve (Late 2006) Processor Heat Sink Replacement Instructions 5
Important: Each heat sink is connected to the 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 logic board.
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 logic board.
Lift the heat sink straight up and out of the enclosure.
