In one embodiment, a fan is used to generate airflow through a computer chassis to a fan air inlet. An audible frequency component of the airflow is identified and selected. A sound wave is generated having a generated frequency equal to the selected audible frequency component of the airflow. The generated sound wave is introduced into the airflow with the generated frequency out of phase with the audible frequency component of the airflow. The magnitude of the generated frequency may be selected as a function of fan speed and/or air sensed pressure within the airflow. The frequency, phase, and magnitude of the generated sound wave may be selected and enforced by a baseboard management controller.
