Reverse the removal procedure to install a cooling fan. Align the pin on the fan unit base with the notch on the fan and put the circuit board cooling fan in the fan unit, then use the screws to safety the circuit board cooling fan to the fan unit base. Tighten the screws to a correct tightening torque: 0.98 N∙m to 1.33 N∙m (8.67 lbf∙in to 11.77 lbf∙in) Note: Make sure that you do not pinch cables between the circuit board cooling fan and the fan unit base. Figure 1.
