Thermal induction realizes the speed of the fan. When the engine is hot, the thermal sensor/thermistor/sub-sensitive resistor connected to the fan, the resistance value becomes smaller, the fan power increases, and the opposite happens when the engine becomes cold, so the control of the fan is realized. speed.
여전히 팬을 수동으로 제어하려는 경우 팬 회로와 직렬로 조정 가능한 저항을 연결하여 팬을 자동으로 제어하는 목적을 달성할 수도 있습니다.
One of the fans in your problem is faulty. Check the other fan. The thermistor/sub-sensitive resistor inside the fan may fail. You can use a conductor to directly short the thermistor to see if it is on in high turn. If in the description this thermistor / sub-sensitive resistor burned out. You can change a resistor of the same type, or if you don't think the fan is loud, you might as well short-circuit the thermistor/sub-sensitivity directly.
