Xserve (Early 2009) Take Apart — Processor Heat Sink 145 2010-06-28 First Steps Remove: • Top Cover • Airflow Duct Note: The thermal bond between the processor and heat sink requires thermal grease. You must replace the thermal grease every time your remove the processor and processor heat sink. Tools • ESD wrist strap and mat • Alcohol wipes • Thermal grease • 3-mm Hex wrench Processor Heat Sink
Xserve (Early 2009) Take Apart — Processor Heat Sink 146 2010-06-28 Removal 1 Loosen the four captive screws securing the heat sink to the processor. 2 Pull the connector, not the cable, to disconnect the sensor cable from the logic board. Caution: Each heat sink is connected to the logic board by a small 2-pin thermal sensor cable. Lifting the heat sink too quickly can damage the cable or connector. Because of the tight thermal bond between the processor and the heat sink, be cautious when removing. Do not pull on the cable as you lift the heat sink.
Xserve (Early 2009) Take Apart — Processor Heat Sink 147 2010-06-28 3 Handle the heat sink from the side slotted sides, not the smooth sides. Grasping from the smooth sides can compress the ribs causing permanent damage. 4 Lift the heat sink straight up and out of the enclosure. 5 Gently twist the processor and heat sink in opposite directions. Important: Hold the processor by three corners when removing or replacing the processor. Do not touch the gold pins on the processor or processor socket on the logic board.
Xserve (Early 2009) Take Apart — Processor Heat Sink 148 2010-06-28 Replacement 1 Always hold the processor by three corners. 2 Clean off any existing thermal grease on the heat sink and processor using alcohol wipes provided with the replacement part. 3 Using the syringe, apply 0.1 cc of thermal grease to the top surface of the processor. 4 Do not apply more grease than recommended. Do not allow grease to come in contact with processor frame or processor connectors. 5 Reinstall processor and processor frame. 6 Replace heat sink and secure heat sink connector to logic board. Important: The thermal bond between the processor and heat sink requires thermal grease for proper operation. You must replace the thermal grease on the processor each time you remove or replace the heat sink. Clean the processor and apply new grease as follows Important: Be sure not to get any grease anywhere on the processor other than the very top, flat surface that directly contacts the heat sink

You must replace the thermal grease every time your remove the processor heat sink Tools • ESD wrist strap and mat • Alcohol wipe • Thermal grease • CPU socket cover Processor Note: This procedure applies to the Xserve (Early 2009) single and dual-processor configurations. Important: Xserve (Early 2009) requires thermal grease for proper operation. Every time you remove a processor heat sink, you must replace the grease on the underside of the heat sink. See procedure “Processor Heat Sink.” New grease and alcohol wipes for cleaning off the previous grease are included with replacement heat sinks, processors.
Xserve (Early 2009) Take Apart — Processor 150 2010-06-28 Removal 1 Carefully remove the processor from the heat sink by twisting the heat sink and processor in opposite directions.
