Prerequisites
WARNING:The heat sink may be hot to touch for some time after the system has been powered off. Allow the heat sink to cool before removing it.
Follow the safety guidelines listed in the Safety instructions.
Power off the system and all attached peripherals.
Disconnect the system from the electrical outlet and disconnect the peripherals.
If applicable, remove the system from the rack.
Remove the system cover.
Removing a heat sink:
Using a Torx #T20 screwdriver, loosen the captive screws in the order that is mentioned on the heat sink:
Partially loosen the captive screws 1 and 2 (approximately 3 turns).
Partially loosen the captive screws 3 and 4 (approximately 3 turns).
Loosen the captive screws 1 and 2 completely.
Loosen the captive screws 3 and 4 completely.
NOTE:The captive screw numbers are marked on the heat sink.
Lift the heat sink from the system.
Removing the processor:
Using a Torx #T20 screwdriver, loosen the screws to release the force plate. The sequence to loosen the screws is 3, 2, and 1.
NOTE:The screw numbers are marked on the force plate.
Release the processor socket rail frame by lifting the blue latches.
Holding the blue tab on the processor tray, slide the tray out of the rail frame.
Installing the processor:
Holding the blue tab on the processor tray, slide the tray into the processor socket rail frame until firmly seated.
Push the rail frame down until the blue latches lock into place.
Secure the force plate to the processor socket base by tightening the screws in the sequence 1, 2, and 3. When all three screws are fully threaded, the socket is then actuated. The three screws are tightened to a torque value of 12.0 ± 1.2 lbf-in.
NOTE:The screw numbers are marked on the force plate.
NOTE:Press the force plate while tightening the screws to avoid tilting of the processor cover out of the processor socket.
Installing the heat sink:
If you are using an existing heat sink, remove the thermal grease on the heat sink by using a clean lint-free cloth.
NOTE:For a new heat sink, the thermal paste is preapplied to the heat sink. Remove the protective cover, and install the heat sink.
Use the thermal grease syringe included with your processor kit to apply the grease in a thin spiral on the top of the processor.
CAUTION:Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
NOTE:The thermal grease syringe is intended for single use only. Dispose of the syringe after you use it.
Align the screws on the heat sink with the standoff screws on the system board.
NOTE:The A1 extrusion on the L-type heat sink should face towards the system side.
Using a Torx #T20 screwdriver, tighten the captive screws in the order that is mentioned below:
NOTE:The captive screw numbers are marked on the heat sink and are tightened to a torque value of 12.0 ± 1.2 lbf-in.
Partially tighten the captive screws 1 and 2 (approximately 3 turns).
Partially tighten the captive screws 3 and 4 (approximately 3 turns).
Tighten the captive screws 1 and 2 completely.
Tighten the captive screws 3 and 4 completely.
Replace the system cover.
If applicable, install the system into the rack.
Reconnect the peripherals and connect the system to the electrical outlet, and then power on the system.
