A heat-dissipating fan includes a housing, an impeller, and a circuit board. The housing includes an air channel and a base. The base is mounted in one end of the air channel for supporting the circuit board. The impeller is rotatably mounted on the base and includes a hub and a plurality of blades. The circuit board includes at least one heat-generating electronic element mounted thereon. The heat-generating electronic element extends out of the hub in relation to a longitudinal direction of the housing, with at least one portion of the heat-generating electronic element located on a downstream side of the blades for dissipating heat generated by the heat-generating electronic element.
