The AC fan cools the condenser; not the radiator coolant. The AC works when you turn on the AC or when you select defrost/defog to dry out the cabin air, so that might be the cause. Otherwise, you could have a defective temperature switch, coolant temperature sensor, or a defect in the wiring. Have the system checked.
