Remove a heat sink Torx T30 nut

Follow the instructions in this section to remove a PEEK (Polyether ether ketone) Torx T30 nut on the heat sink.

About this task

  • Go over Installation Guidelines to ensure that you work safely.

  • Turn off the server and peripheral devices and disconnect the power cords and all external cables (see Power off the server).

  • 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.

  • Do not touch the processor contacts. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.

The heat sink, processor, and processor carrier for the system might be different from those shown in the illustrations.


  1. Make preparations for this task.
    1. Remove the top cover (see Remove the top cover).
    2. Remove the following components depending on the location of the processor that is to be removed:
      • If the processor is located on the processor and memory expansion tray, do not remove the expansion tray. Only remove the air baffle from the expansion tray.
        Figure 1. Removing the air baffle from the expansion tray

      • If the processor is located on the system board:
        1. Remove one of the following components.
        2. Remove the expansion tray air baffle.
        Figure 2. Removing the expansion tray air baffle

    3. Remove the PHM. See Remove a processor and heat sink.
  2. Remove the Torx T30 nut.

    Do not touch the gold contacts on the bottom of the processor.
    1. Rotate the anti-tilt wire bail inwards.
    2. Push the upper edge of the Torx T30 nut towards the center of the heat sink until it disengages.
    3. Remove the Torx T30 nut.
      Visually inspect the removed Torx T30 nut, if the nut is cracked or damaged, make sure no debris or broken pieces are left inside the server.

After you finish

  1. Install a new Torx T30 nut. See Install a heat sink Torx T30 nut.

  2. Proceed to complete the parts replacement (see Complete the parts replacement).
