Abstract: The fan controlling method comprises following steps: Firstly, a current rotation speed of a fan is obtained. Next, whether the current rotation speed is not greater than an expected rotation speed corresponding to the first type is determined. Then, whether a rotation speed variance between the current rotation speed and the expected rotation speed is not greater than a reasonable variance is determined when the current rotation speed is not greater than the expected rotation speed. Then, a determination that the fan belongs to the first type is made when the rotation speed variance is not greater than the reasonable variance, and a determination that the fan belongs to the second type is made when the rotation speed variance is greater than the reasonable variance, wherein the second type is different from the first type.

Abstract: An electronic device includes a thermal sensor and a microprocessor. The thermal sensor is configured to sense an internal temperature of the electronic device and provide multiple temperature values according to the sensing result. The microprocessor is coupled to the thermal sensor and configured to receive the temperature values. The microprocessor determines a high threshold value and a low threshold value according to the temperature values and filters the temperature values in sequence according to the high threshold value and the low threshold value. When one of the temperature values is not higher than the high threshold value and is not lower than the low threshold value, the microprocessor outputs the temperature value, and when the temperature value is higher than the high threshold value or is lower than the low threshold value, the microprocessor outputs a predetermined temperature value instead of the temperature value.
