Abstract:
1. A method of controlling a heat-dissipating fan of a computer device, which comprises steps: (A) using a first sensor unit to detect an inner status of the computer device to thereby output a first signal, and using a second sensor unit to detect an outer status of the computer device to thereby output a second signal; (B) using a controller to receive the first signal to thereby control the heat-dissipating fan to operate at a rotating speed based on the first signal, wherein the controller is connected to the first sensor unit; (C) using the controller to compare the first signal with a first setting, and using the controller to determine whether the second signal is received, wherein the controller is connected to the second sensor unit; (D) using the controller to reduce the rotating speed of the heat-dissipating fan when the controller determines that the first signal is not greater than the first setting and that a time interval in which the controller does not receive the second signal is greater than a second setting, so as to reduce a noise value produced by the heat-dissipating fan; (E) using the first signal to adjust the rotating speed when the controller determines that the first signal is greater than the first setting or the second signal is received; and (F) continuously using the controller to determine the first signal and the second signal for controlling the heat-dissipating fan.
