A DC fan 4 wire is a DC fan that has 4 wires. It differs from 2-wire and 3-wire fans in that a 4-wire fan has more powerful control features. The wiring is usually as follows: black or brown to the negative power supply, red or yellow to the positive power supply, green or blue to the speed control wire, and white or gray to the speed monitoring wire. Among them, the fourth wire is used to control the speed, without it the fan will run at full load.
The advantage of a 4-wire DC fan is that it allows you to regulate the speed of the fan through the RPM control wire, thus enabling precise control of the temperature of the device. In addition, the 4-wire fan can also realize stepless speed regulation of the fan through the PWM speed control function, which further improves the control precision and flexibility of the fan.
It should be noted that the wiring of a 4-wire DC fan may vary from manufacturer to manufacturer, so you should carefully read the fan specification and circuit knowledge before wiring to ensure correct wiring.
