Abstract
Disclosed aspects relate to cooling electronics. A set of recirculation flaps is coupled with a cooling fan. At least one recirculation flap has a ferrous material. In various embodiments, the set of recirculation flaps is arranged in an open position in response to air pressure from the cooling fan, and is arranged in a closed position in response to substantially no air pressure from the cooling fan. A controller is coupled with the cooling fan. The controller indicates a set of indicated positions for the set of recirculation flaps based on a tachometer value. An electromagnet is connected with the controller to position the set of recirculation flaps in the set of indicated positions using the ferrous material. In various embodiments, the electromagnet engages the ferrous material to arrange the set of recirculation flaps in an open position.
