Installing a processor and heat sink module
Prerequisites
CAUTION: Never remove the heat sink from a processor unless you intend to replace the processor. The heat sink is necessary to
maintain proper thermal conditions.
1 Follow the safety guidelines listed in Safety instructions.
2 If installed, remove the processor/DIMM blank and CPU dust cover.
The procedure to remove the processor/DIMM blank is similar to that of the memory module.
Steps
1 Align the pin 1 indicator of the heat sink to the system board and then place the processor and heat sink module (PHM) on the
processor socket.
CAUTION: To avoid damaging the ns on the heat sink, do not press down on the heat sink
ns.
NOTE: Ensure that the PHM is held parallel to the system board to prevent damaging the components.
2 Push the blue retention clips inward to allow the heat sink to drop into place.
3 Using the Torx #T30 screwdriver, tighten the screws on the heat sink in the order below:
a Partially tighten the rst screw (approximately 3 turns).
b Tighten the second screw completely.
c Return to the rst screw and tighten it completely.
If the PHM slips o the blue retention clips when the screws are partially tightened, follow these steps to secure the PHM:
a Loosen both the heat sink screws completely.
b Lower the PHM on to the blue retention clips, follow the procedure described in step 2.
c Secure the PHM to the system board, follow the procedure described in step 4.
NOTE
: The processor and heat sink module retention screws should not be tightened to more than 0.13 kgf-m (1.35 N.m
or 12 in-lbf).
