Abstract: A method for controlling a plurality of fans associated with a cooling package is provided. The method includes providing a first airflow through a first heat exchanger using a first fan. The method includes regulating a speed of the first fan. The method also includes providing a second airflow through a second heat exchanger using a second fan. The second heat exchanger is spaced apart from the first heat exchanger. The method further includes regulating a speed of the second fan. The regulation of the speed of the second fan is configured to control a recirculation of at least a portion of the first airflow through the second fan.
