Abstract
A fan assembly includes a first fan, a second fan, and a controller. The controller is configured to determine that an air movement demand corresponds to operation of the first fan and the second fan at a resonance speed, instruct the first fan to operate at a first speed which is less than the resonance speed, and instruct the second fan to operate at a second speed which is greater than the resonance speed.
