Installing a 1U or high-performance heatsink

This procedure shows a standard heatsink as an example. The installation process is the same for both the standard and high-performance heatsinks.

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

Prerequisites

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

  • The components included with the hardware option kit

  • T-20 Torx screwdriver

  • 1.0 gm (0.5 ml) or two 0.5 gm (0.25 ml) of thermal grease

  • Alcohol wipe

Procedure
  1. Power down the server.
  2. Remove all power:
    1. Disconnect each power cord from the power source.
    2. Disconnect each power cord from the server.
  3. Do one of the following:
  4. Remove the access panel.
  5. Do one of the following:
  6. Allow the existing heatsink to cool.
  7. Remove the heatsink:
    CAUTION:

    To prevent mechanical damage or depositing oil on your hands or other contaminant to the heatsink contact surface, hold the heatsink only by the edge of its base plate. Do not touch the heatsink fins.

    CAUTION:

    Heatsink screws must be tightened and loosened in alternating sequence. Do not overtighten the screws as this might damage the system board or the processor socket.

    1. Use a T-20 Torx screwdriver to loosen the captive screws in the sequence specified on the heatsink label.
    2. Lift the heatsink away from the system board.

      Removing the heatsink
    3. Place the heatsink on a flat work surface with its contact side facing upward.
  8. Use an alcohol wipe to remove the existing thermal grease from the processor.

    Allow the alcohol to evaporate before continuing.

  9. Remove the thermal interface protective cover from the new heatsink.
  10. Install the heatsink:
    CAUTION:

    To prevent mechanical damage or depositing oil on your hands or other contaminant to the heatsink contact surface, hold the heatsink only by the edge of its base plate. Do not touch the heatsink fins.

    CAUTION:

    To prevent thermal failure or component damage, do not move the heatsink once the bottom of its base plate touches the top of the processor. Excessive heatsink movement can cause the thermal grease to smear and become uneven. Voids in the compound can adversely impact the transfer of heat away from the processor.

    CAUTION:

    Heatsink screws must be tightened and loosened in alternating sequence. Do not overtighten the screws as this might damage the system board or the processor socket.

    1. Position the heatsink on top of the processor, ensuring that it is properly seated before securing the screws.
    2. Use a T-20 Torx screwdriver to tighten the captive screws in the sequence specified on the heatsink label.

      When using a torque wrench to tighten the screws, apply a torque of 1.58 N-m (14 lbf-in).


    Installing the heatsink
  11. Do one of the following:
  12. Install the access panel.
  13. Install the server into the rack.
  14. Connect each power cord to the server.
  15. Connect each power cord to the power source.
  16. Power up the server.

The installation is complete.
