With the long-term operation of the computer, the computer fan will also produce a certain temperature while cooling the CPU.If the temperature is too high, it will also affect the life of the fan or cause damage.

        This computer cooling fan temperature warning device comprises a fan temperature detection module, a singlechip, a warning display module and a fan rotation speed control module, and is characterized in that the temperature detection module inputs signals to the singlechip, and the singlechip controls the warning display module and the fan rotation speed control module.

        The fan temperature is detected by the fan temperature detection module, and a signal is input to the single chip microcomputer.According to the input signal, the single chip microcomputer controls the warning display module to display warning information while controlling the rotation speed of the fan to cool down.
