WebMay 8, 2024 · The PWM is a wire that essentially connects to a mosfet of some kind, actually within the fan. By default, the fan is drawing some of the 12v to the mosfet itself and thus, by default, it will spin as the mosfet is at a high state. The only way to stop the fan spinning is to make the mosfet change to a low state. WebApr 16, 2012 · Product Details.
