1. A serial fan set, comprising:
- a rotation speed control module, which is used to receive an input signal, and output a rotation speed driving signal corresponding to the input signal in accordance with the rotation speed-matching relations of a rotation speed-matching curve;
a first fan, connected to the rotation speed control module and rotating at a corresponding rotation speed; and
a second fan, connected to the rotation speed control module and rotating at a corresponding rotation speed;
wherein the rotation speed-matching curve represents the rotation speed-matching relations of the first fan and the second fan that correspond to the optimum Air Pressure vs. Air Flow relations of the first fan and the second fan during their operations.

Abstract
A serial fan set and rotation speed-matching curve generation method thereof are provided. The serial fan set comprises a rotation speed control module, a first fan and a second fan, in which the rotation speed control module is used to receive the power signal and produce the rotation speed driving signal corresponding to the power signal in accordance with the relations of the rotation speed-matching curve, so that the first fan and the second fan are operated at the matching rotation speed, thus producing the optimum operation efficiency and achieving the purpose of controlling the serial fan set.
