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.
Ä CAUTION: 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.
