Figure 103. Installing the heat sink onto the processor Next steps Install the processor and heat sink module. 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. WARNING: The heat sink may be hot to touch for some time after the system has been powered down. Allow the heat sink to cool before removing it. 1. Follow the safety guidelines listed in Safety instructions. 2. If installed, remove the processor 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 fins on the heat sink, do not press down on the heat sink fins. 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 first screw (approximately 3 turns). b. Tighten the second screw completely. 130 Installing and removing system components

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.
WARNING:
The heat sink may be hot to touch for some time after the system has been powered down. Allow the
heat sink to cool before removing it.
1.
Follow the safety guidelines listed in
Safety instructions
.
2.
If installed, remove the processor 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 fins on the heat sink, do not press down on the heat sink fins.
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 first screw (approximately 3 turns).
b.
Tighten the second screw completely.
