Dell EMC PowerEdge C4140 Installation and Service Manual

Installing the SXM2-GPU Heat Sink

1. If you are using an existing SXM2-GPU heat sink, remove the thermal grease from the heat sink by using a clean lint-free cloth.
2. Using the thermal grease syringe included with your processor kit 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 the syringe after you use it.
3. Align the screws on the heat sink with the standoffs on the system board.

   

4. Using a Philips #2 screwdriver tighten the screws in the following order to secure the heat sink to the system board:
   1. Tighten the first screw three turns.
   2. Tighten the screw diagonally opposite to the screw you tightened.

   

5. Repeat the procedure for the remaining two screws.
6. Return to the first screw and tighten it.
7. Following the same diagonal pattern, tighten the remaining screws.
