The temperature controlled cooling fan uses temperature to control the cooling fan. Its principle is to sense the high temperature rise around the cooling fan, thereby increasing the speed of the cooling fan and increasing the flow of air (air volume). It is based on the use of a thermistor to detect temperature. The sensor installed on the hub of the cooling fan can detect the temperature of the cooling fan. In such a configuration, the fan must be completely installed. After installation, The thermistor sensor can be sensed through a special connecting wire.
The operating speed of the temperature controlled cooling fan varies with the temperature. When the temperature controlled cooling fan operates at a slower speed, it only produces lower noise and low power consumption.
