Principle of PWM intelligent temperature-controlled cooling fan (Source: STC-Cable)

Posted filed under Advertising & Marketing.

Traditional temperature-controlled fans use a temperature probe near the fan bearing to detect the temperature of the fan’s air inlet, thereby adjusting the fan’s speed. Although this kind of temperature control solves certain problems, it has rough accuracy, and the temperature control speed can only achieve high-speed and low-speed bipolar speed changes. PWM is the abbreviation of pulse width modulation circuits, which has been widely used in industrial control and microcontrollers. Intel combined it with the motherboard’s CPU temperature detection and applied it to accurately control the speed of the radiator fan, and achieved good results.
