A wireless device charger configured to produce an alternating magnetic field, thereby inducing an alternating electrical current within a capture coil of a personal electronic device proximate to the wireless device charger, said wireless device charger includes a source coil having a ferrite element configured to generate the alternating magnetic field, a housing formed of a thermally conductive material in thermal communication with the ferrite element, and an air movement device configured to produce an air flow across a surface of the housing flowing from an air inlet to an air outlet, thereby reducing a housing temperature. The surface of the housing defines a plurality of fins extending along the housing in a direction of the air flow. At least one fin in the plurality of fins has a non-symmetric surface, thereby creating turbulence in the air flow.
