Remove a processor and heat sink
This task has instructions for removing an assembled processor and heat sink, known as a processor-heat-sink module (PHM). This task requires a Torx T30 screwdriver. This procedure must be executed by a trained technician.
About this task
Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
Keep static-sensitive parts in their static-protective packages until installation to prevent exposure to static electricity. Handle the parts with an electrostatic-discharge wrist strap or other grounding systems. Place the parts on a static-protective surface.
If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the server from the rack. See Remove the server from the rack (friction rails) or Remove the server from the rack (slide rails).
Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.
Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.
Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as the electrical connectors in the processor socket.
Remove and install only one PHM at a time. If the processor board supports multiple processors, install the PHMs starting with the first processor socket.

Procedure
- If the processor comes with a T-shaped heat sink, fully loosen the two heat sink screws as shown.Figure 2. Loosening T-shaped heat sink screws
- Remove the PHM from the processor board.Figure 3. Removing a PHM
Fully loosen the Torx T30 nuts on the PHM in the removal sequence shown on the heat-sink label.
Rotate the anti-tilt wire bails inward.
Carefully lift the PHM from the processor socket. If the PHM cannot be fully lifted out of the socket, further loosen the Torx T30 nuts and try lifting the PHM again.NoteDo not touch the contacts on the bottom of the processor.
Keep the processor socket clean from any object to prevent possible damages.
After you finish
Each processor socket must always contain a cover or a PHM. Protect empty processor sockets with a cover or install a new PHM.
If you are not going to install a PHM back, cover the processor socket with the socket cover and install a PHM filler.
- Open the retaining clip on each end of the memory module slots next to the left and right sides of the processor two slot.
- Align the PHM filler with the slots, and place the filler on the slots with both hands. Firmly press the filler straight down into the slots until the retaining clips snap into the locked position.
If you are removing the PHM as part of a processor board replacement, set the PHM aside.
If you are reusing the processor or heat sink, separate the processor from its retainer. See Separate the processor from carrier and heat sink.
If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
