Claim:
1. A device for controlling a fan of a display, suitable to control a rotation-speed of the fan and the device comprising: a temperature sensor, sensing a current temperature of the display; a memory, storing the current temperature of the display, a first setting-temperature and a second setting-temperature, wherein the first setting-temperature is used to control the fan for rotation or not, and the second setting-temperature is used to control the fan for turning off or not; a control module, coupled to the temperature sensor and the memory, and coupled to the fan of the display for comparing the current temperature of the display with the first setting-temperature, comparing the current temperature of the display with the second setting-temperature, and judging a variation of the current temperature of the display to control the rotation-speed of the fan, wherein if the control module judges out the current temperature of the display sensed by the temperature sensor rises, the control module raises the rotation-speed of the fan when the rotation-speed of the fan is lower than a maximum rotation-speed; and wherein if the control module judges out the current temperature of the display is lower than or equal to the second setting-temperature, the control module turns off the fan.
