Installing a 1U or high performance heatsink

This procedure shows a standard heatsink as an example. The installation process is the same for all heatsinks.

Hewlett Packard Enterprise recommends identifying the processor, heatsink, and socket components before performing this procedure.


Before you perform this procedure, make sure that you have the following items available:

  • The components included with the hardware option kit

  • T-30 Torx screwdriver

  • Thermal grease

  • Alcohol wipe

  • 1/4-inch flathead screwdriver

  1. Observe the following alerts.
    CAUTION: To prevent possible server malfunction and damage to the equipment, multiprocessor configurations must contain processors with the same part number.
    CAUTION: If installing a processor with a faster speed, update the system ROM before installing the processor.

    To download firmware and view installation instructions, see the Hewlett Packard Enterprise Support Center website.

    CAUTION: THE CONTACTS ARE VERY FRAGILE AND EASILY DAMAGED. To avoid damage to the socket or processor, do not touch the contacts.
  2. Power down the server.
  3. Remove all power:
    1. Disconnect each power cord from the power source.
    2. Disconnect each power cord from the server.
  4. Do one of the following:
  5. Remove the access panel.
  6. Do one of the following:
  7. Remove the processor heatsink assembly:
    1. Allow the heatsink to cool.
    2. Loosen the heatsink nuts in the order specified by the label on the heatsink.

    3. Lift the processor heatsink assembly and move it away from the system board.
    4. Turn the assembly over and place it on a work surface with the processor facing up.
    5. Install the dust cover.
  8. Separate the processor from the heatsink:
    1. Locate the release slot between the frame and heatsink.
      The release slot is across from the Pin 1 indicator and is labeled with a screwdriver.
    2. Insert a 1/4" flathead screwdriver into the release slot.
      Be sure that the screwdriver is between the plastic frame and the heatsink.
    3. To lift the processor frame away from the heatsink, slowly rotate the screwdriver.

    4. Unlatch the remaining corners of the frame.
    5. Separate the frame from the heatsink.
  9. Using an alcohol wipe, remove the existing thermal grease.
    Allow solvent to dry before making contact with thermal grease.
  10. Align the latches and pin 1 indicator, and then install the frame to the heatsink.
    Verify that all of the latches are engaged with the heatsink.

  11. Install the processor heatsink assembly.

The installation is complete.
