4. With a T30 bit torque driver set to a force of 8.0 in-lbf (0.904 N-m), 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.
Important: Do not use a force greater than 8.0 in-lbf (0.904 N-m). Exceeding this
force may over-torque the screw, causing damage to the processor, heatsink, and
screw.
