  • Fan control of a computer system based on power ratio
    Patent number: 10342157
    Abstract: A method for controlling a fan is described and includes controlling a rotation speed of a fan according to a first rotation speed time-variable rate by a controller, and controlling the rotation speed of the fan according to a second rotation speed time-variable rate by the controller in response to a change in an operating parameter of a target device, where the fan and target device are for use in a computer system.
    Type: Grant

  • Fan control of a computer system based on power ratio
    Patent number: 10278304
    Abstract: A fan control system for a computer system is provided. The computer system includes a fan and a target device. The fan control system includes a controller to control the rotation speed of the fan. The controller determines a time-variable rate of the rotation speed according to an operating parameter of the target device. Particularly, the controller determines the time-variable rate of the rotation speed according to a ratio of the consumed power to the rated power of the target device. Alternatively, the controller can determine the rotation speed according to the ratio of the consumed power to the rated power of the target device.
