Abstract
A fan with increased heat-removing ability and reduced noise in operation includes a hub, a baffle, a first blade layer, and a second blade layer. The first blade layer includes a plurality of first blades, and the second blade layer includes a plurality of second blades. An orthogonal projection of each of the plurality of first blades on the baffle is located between orthogonal projections of adjacent two of the plurality of second blades on the baffle. A length of the plurality of first blades is greater or less than a length of the plurality of second blades to avoid any resonance. An electronic device including the fan is also disclosed.
