Abstract: This design presented a new cooling fan control system，using the cheap C8051F330 SCM as the system control unit. The temperature sensor chosed DS18B20 whose volume is small, IR2130 drived bridge type inverterr. The design of the control system is considerably reduced volume,its speed can be appropriately adjusted according to the temperature,and is applicable for various applications.
