Abstract
A device is suitable for controlling a rotation-speed of a fan of a display. The device includes a temperature sensor for sensing a current temperature of the display, a memory for storing the current temperature of the display and a first and a second setting-temperature and a control module coupled to the temperature sensor and the memory and adapted to couple to the fan of the display. The control module compares the current temperature of the display with the first and the second setting-temperatures and judging the variation of the current temperature of the display to control the rotation-speed of the fan. 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.
