A plurality of fans is connectable to a heat exchanger arrangement having a plurality of separated cooling loops. At least one of the fans is operable to move air through at least two of the cooling loops, and at least one other fan is operable to move air through at least one of the cooling loops. A control system includes at least one controller and is operable to control each of the at least one fan using a respective control strategy correlating temperature values with fan outputs, and to control each of the at least one other fan using a respective control strategy that is different from each control strategy used to control the at least one fan.
