The third reason is going to be temperature. With PWM fans, you can set custom fan curves in programs like Fan Control, so that if your CPU or GPU hits a certain temperature, the fan's RPM gets ...

meaning that a small thermistor would speed up the the fan as the temperature increased. Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which ...

A PWM-controlled fan, operating between 1000 and 3000 rpm, ensures variable cooling with low noise output, rated at 23 dBA at 1600 rpm under a 40 °C CPU load. The inclusion of a mounting ...

The PSU's cooling system is managed by a 120 mm fluid dynamic bearing PWM fan that supports zero RPM ... The motherboard 20+4 pin, CPU, PCIe 6+2 pin, and 12V-2x6 cables come with pre-installed ...
