The characteristic of the DC cooling fan with PWM function is that it can intelligently adjust the speed of the DC cooling fan according to the frequency of use of the product. We know that the higher the speed, the greater the wind, the better the heat dissipation. When we use the frequency low, the fan rotates very slowly and is very quiet. Just like when we use a computer to play games, the CPU frequency is high, and the cooling fan with PWM function rotates faster. When we just use ordinary office software, the DC cooling fan rotates very slowly and is very quiet. So, DC The cooling fan is designed with PWM function to have a certain mute effect, which can bring more comfort to life.
