Abstract
The disclosure relates to a method, circuit, and electronic device for controlling a rotation speed of a fan. The method provides a multistage function curve associates temperatures with rotation speed values. The multistage function curve comprises a first steady-state function segment with slope of zero, a second steady-state function segment with slope of zero and N function segments positioned between the first and second steady-state function segments. N is a positive integer. The slope of a (i+1)function segment is greater than that of an ifunction segment, and i is a positive integer in the range from 1 to N. The electronic device comprising the circuit may use the temperature of the processor based on the multistage function curve to dynamically control the rotation speed.
