The difference is not significant. The 5-blade electric fan has a smaller single blade area and a smaller air effect scale, so the blade vibration is smaller. The noise and wind cutting sound generated are relatively low, and the wind pressure blown out is also relatively low, making it feel more comfortable. So the commonly claimed silent fan or comfortable fan is mostly a 5-leaf electric fan blade, which has a higher cost than a 3-leaf electric fan blade

The scale at the junction between the leaf root and the central axis is narrow.

As for the smooth and comfortable air supply, many fans intentionally plan to simulate natural wind with changes in wind speed, which cannot guarantee the necessary factors. As for heat dissipation, if it refers to providing people with heat dissipation, it means that the wind is strong, related to power, and not related to the number of blades.
