Abstract

A computer and a control method for smart fan thereof are provided, wherein the computer includes a processor configured to control a smart fan under an UETFI bios mode. A sensed temperature value from a temperature sensor, and a current speed value of the smart fan are acquired. A real-time temperature curve and a real-time speed curve are traced in a dynamic updating zone of a graphical interface respectively according to the current temperature and the current speed value. A first control point and a second control point, which correspond to the smart fan, are obtained via a control zone of the graphical interface. A control curve is traced in the graphical interface according to the first and second control points. The speed of the smart fan is controlled according to the control curve.
