A B AF002840 Figure 25. Closing the Load Plate and Socket Lever Installing the Heatsink Caution: Improper installation can damage the heatsink. Pay close attention to the steps and perform each step exactly as indicated to avoid damage. Caution: The heatsink has Thermal Interface Material (TIM) located on the bottom of it. Use caution when you unpack the heatsink so you do not damage the TIM. Note: New unused heatsinks have adequate TIM on the bottom. If you are reusing a heatsink from replacing a processor, make sure there is adequate TIM present on the heatsink to support processor cooling. 17. Remove the protective film on the TIM, if present. 18. Orient the heatsink over the processor as shown in Figure 26. The heatsink fins must be positioned as shown to provide correct airflow through the system. Airflow goes from front-to-back of the compute module. Note: Figure 26 illustrates the heatsink orientation for CPU 1. The heatsink over CPU 2 should be oriented in a reverse direction so as to provide correct airflow through the compute module. 19. Set the heatsink over the processor, lining up the four captive screws with the four posts surrounding the processor. 20. Loosely screw in the captive screws on the heatsink corners in a diagonal manner according to the numbers shown in Figure 26 as follows: a. Starting with the screw at location 1, engage the screw threads by giving it two rotations in the clockwise direction and stop. (IMPORTANT: Do not fully tighten.) b. Proceed to the screw at location 2 and engage the screw threads by giving it two rotations and stop. c. Engage screws at locations 3 and 4 by giving each screw two rotations and then stop. d. Repeat steps 20a through 20c by giving each screw two rotations each time until all screws are lightly tightened upto a maximum of 8 inch-lbs torque. 30 Intel® Compute Module MFS5520VI User Guide
