Installing a Heatsink
A passive type heatsink is used on the X13SCH-SYS motherboard.
Note: Do not apply any thermal grease to the heatsink or the CPU die; the required amount
has already been applied.
1. Place the heatsink on top of the CPU so that the four mounting holes are aligned with
those on the heatsink retention mechanism.
2. With a Phillips bit torque driver, gradually tighten the four screws to ensure even
pressure. You can start with any screw, but make sure to tighten the screws in a
diagonal pattern.
Note: Do not use a force greater than 6.0 in-lbf (0.678 N-m). Exceeding this force may over-
torque the screw, causing damage to the processor, heatsink, and screw.
3. Examine all corners to ensure that the heatsink is firmly attached.
Note: The figure above is for illustrative purposes only.
