Many products require DC cooling fans to be more silent. There are various designs. The representative one is the DC cooling fan with PWM function. Is this design more silent?

The DC cooling fan with PWM function is characterized by adjusting the speed of DC cooling fan intelligently according to the frequency of product use. We know that the higher the speed, the larger the wind, the better the heat dissipation. And when we use it at a low frequency, the fan turns very slowly and quietly. For example, when we play games with computers, we use CPU with high frequency, and the cooling fan with PWM function turns faster. When we only use ordinary office software, the DC cooling fan turns very slowly and quietly.

Therefore, DC cooling fan designed with PWM function has a certain silence effect, which can bring more comfort to life.
