Abstract
Methods and systems may provide for a computing system including an electrical component, a heat exchanger coupled to the electrical component, and a fan having a rotor with a plurality of blades, one or more inlet sides and one or more outlet sides disposed adjacent to the heat exchanger. The computing system may also include an obstruction disposed adjacent to at least one of the one or more inlet sides of the fan, wherein a tone to be generated by the obstruction reduces a tonal noise associated with the fan during operation.
