Removing the Heatsink
To install or remove the processor, you must first remove the heatsink.
Caution: Improper removal can damage the heatsink. Pay close attention to the steps and perform
each step exactly as indicated to avoid damage.
To remove the heatsink, follow these steps:
1. Remove the PCI riser assembly. For instructions, see “Removing the PCI Riser
Assembly” on page 50 .
2. Remove the processor air duct. For instructions, see “Removing the Processor Air
Duct” on page 56 .
3. Loosen the four captive screws on the heatsink corners in a diagonal manner
according to the numbers shown in Figure 48 as follows:
a. Starting with the screw at location 1, loosen it by giving it two rotations in the
anticlockwise direction and stop. ( IMPORTANT: Do not fully loosen. )
b. Proceed to the screw at location 2 and loosen it by giving it two rotations and
stop.
c. Loosen screws at locations 3 and 4 by giving each screw two rotations and then
stop.
d. Repeat steps 3a through 3c by giving each screw two rotations each time until all
screws are loosened.
4. Do one of the following:
— If removing the heatsink for the first time, do the following:
i. Lift the heatsink from the board.
ii. Remove and discard the spacer (see letter “C” in Figure 48 ).
Note: The system is shipped with a spacer installed between the heatsink and the
processor socket to protect the socket protective cover. This spacer will need
to be removed and discarded before installing the processor.
— If a processor is already installed, do the following:
i. Twist the heatsink slightly to break the seal between the heatsink and the
processor.
ii. Lift the heatsink from the processor. If it does not pull up easily, twist the
heatsink again. Do not force the heatsink from the processor. Doing so
could damage the processor.
