description A fan (2) includes a central hub (22), and a plurality of spaced and substantially sector-shaped blades (24) radially extending from the central hub. The blades surround the central hub. Shapes of the blades are similar. Sizes of the blades are all different from one another. Spacings between any two adjacent blades are all different from one another. The blades can therefore be configured such that a natural frequency of the blades is outside a range of a working frequency of a corresponding heat dissipation assembly which is used to dissipate heat from a corresponding electronic device. Resonance of the blades can therefore be completely avoided. Noise and vibration of the blades when the fan is operated can therefore be minimized.
