Abstract: A heat-dissipating fan has two intakes and can be used for mounting on a heat-generating element. The heat-dissipating fan mainly includes a base, a blade assembly, an outer casing and a cover. The base has an accommodating trough for accommodating the blade assembly. The bottom of the accommodating trough is provided with a plurality of first intakes. Further, the outer casing is provided above the base and correspondingly combined with the base. The center of the outer casing is provided with a second intake. Finally, the cover is provided under the base and correspondingly connected to the bottom of the base. With the above arrangement, when two adjacent heat-dissipating fans operate at the same time, with the closing action of the cover, the interference in the air-extracting action between the facing intakes of the two adjacent heat-dissipating fans can be reduced to keep the heat-dissipating effect of the fan.
