Caution: Each heat sink is connected to the logic board by a small 2-pin thermal sensor 2.
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. 3.
Lift the heat sink straight up and out of the enclosure. 4.
Using the Thermal Grease Kit
Important: Before re-installing each processor heat sink, you must clean off any existing thermal

clean the top of the processor that sits below the heat sink and apply new thermal grease. The
following steps explain how to clean the processor and apply the grease.
Release the latch on the metal processor holder. 1.
Rotate the top of the holder to the open position. 2.
