Dell PowerEdge FC430 Owner's Manual

Installing a heat sink

Prerequisites

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.
NOTE: This is a Field Replaceable Unit (FRU). Removal and installation procedures should be performed only by Dell certified service technicians.
  1. Follow the safety guidelines listed in the Safety instructions section.
  2. Follow the procedure listed in the Before working inside your system section.
  3. Keep the Phillips #2 screwdriver ready.
  4. Install the processor.

Steps

  1. If you are using an existing heat sink, remove the thermal grease from the heat sink by using a clean lint-free cloth.
  2. Use the thermal grease syringe included with your processor kit to apply the grease in a thin spiral on the top of the processor.
    CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
    NOTE: The thermal grease syringe is intended for one-time use only. Dispose of the syringe after you use it.

  3. Place the heat sink onto the processor.
  4. Tighten one of the four screws to secure the heat sink to the system board.
  5. Tighten the screw diagonally opposite to the first screw you have tightened.
    NOTE: Do not over-tighten the heat sink retention screws when installing the heat sink. To prevent over-tightening, tighten the retention screw until resistance is felt, and stop after the screw is seated. The screw tension should not be more than 6 in-lb (6.9 kg-cm).
  6. Repeat the procedure for the remaining two screws.

Next steps

  1. Follow the procedure listed in the After working inside your system section.
  2. While booting, press F2 to enter System Setup and verify that the processor information matches the new system configuration.
  3. Run the system diagnostics to verify that the new processor operates correctly.
