FAQ

A 3 pin case fan is a computer cooling fan that connects to your motherboard or fan controller using a 3 pin connector. Unlike 4 pin PWM fans, 3 pin fans control speed through voltage regulation rather than pulse-width modulation, offering basic speed control.

Yes, you can connect a 3 pin case fan to a 4 pin motherboard header. The fan will operate normally, but you won't have PWM speed control; speed will be adjusted by voltage instead.

Most fan controllers support 3 pin case fans, allowing you to manually adjust fan speeds by controlling the voltage supplied to the fan.

Yes, 3 pin case fans typically include an RPM (revolutions per minute) sensor wire, allowing you to monitor fan speed through your motherboard or fan controller.

You can use a 3 pin fan splitter cable to connect multiple 3 pin case fans to a single motherboard or controller header, but make sure not to exceed the power rating of the header.
