12.2.2 Removing the Heatsink/Processor Assembly

Once the system has been prepared (section 11.1.1) for processor removal, the heatsink may be separated from the processor using the following procedure:

1.Prepare the computer for disassembly.

2.Remove the access panel, and, if necessary, rotate the computer to ensure that the system board is parallel to the work table (desktop position).

3.On hp workstation xw4000 systems use the following procedure (for hp workstation xw6000 systems go to step 4):

a.Disconnect the heatsink fan power cable 1 from the system board connector (see the figure below).

b.Ensure that the heatsink is warm to the touch. Release the two clips 2 retaining the heatsink/fan assembly to the processor socket and twist the heatsink/fan assembly off the processor.

ÄCAUTION: Always twist when trying to remove a heatsink. If the bond between the heatsink and the processor does not break with moderate twisting pressure then repeat the warm-up procedure described previously. Never pull the heatsink straight out or damage may occur to the processor, socket, or both.

c.Raise the processor locking lever 3 up to the upright position.

d.Remove the processor by grasping it by the edges and pulling it straight up and out of the socket.
