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.

Procedure

1. Make preparations for this task.
   1. Remove the top cover (see Remove the top cover).
   2. Remove both PCIe riser cages or fillers, the chassis air baffle, and the PCIe expansion tray (see Remove a 4U PCIe riser cage, Remove the chassis air baffle, and Remove the 4U PCIe expansion tray).
   3. 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.
        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.
           • System air baffle (see Remove the system board air baffle)
           • Processor and memory expansion tray and expansion tray air baffle (see Remove the processor and memory expansion tray)
        2. Remove the expansion tray air baffle.
        Figure 2. Removing the expansion tray air baffle
        
        
   4. Remove the PHM. See Remove a processor and heat sink.
2. Remove the Torx T30 nut.

   Note

   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.
      Attention

      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.
