A system for both providing air flow through a condenser core of an air conditioner and ventilating an engine compartment in a work machine. A control system for controlling the air flow through the condenser core and through the engine compartment includes a signal generating mechanism associated with the air conditioner operable to output a signal to the control system indicative of a desired fan speed, at least one sensor positioned in the engine compartment for determining the air temperature therein, and a controller coupled to the signal generating mechanism and to the at least one sensor for outputting a signal to the fan to control the speed thereof, the output signal being indicative of the highest fan speed dictated by the signals received from the signal generating mechanism and from the at least one sensor.
