4 Wire Fans

4 Wire Fans 4 wire fans explained. a 4 wire cpu (motherboard) fan is a standard brushless dc (bldc) fan, but has four wires extending from the casing. each of these wires serves a specific purpose. note that chassis and cpu fans may use either 3 pin or 4 pin power connectors. 3 pin connectors are usually used for the smaller chassis fans with lower power. Chassis and processor fans use either a three wire or four wire connector. the three wire connectors are for small chassis fans with lower power consumption. the four wire connectors are for processor fans with higher power consumption. three wire fan connecting to a four pin fan header. fan header pinouts.

Learn how to wire a 4 wire computer fan using a wiring diagram, including step by step instructions and illustrations. discover the different color codes and their corresponding functions for the fan's power, ground, pwm, and tachometer wires. explore common wiring configurations for connecting the fan to a motherboard or an external power source. get started on your diy computer cooling. The 4 wire setup includes power, ground, tachometer, and pulse width modulation (pwm) wires. the power wire of the 4 wire fan connects to the 12v power supply of your computer, providing the necessary energy for the fan to operate. the ground wire, on the other hand, completes the electrical circuit, ensuring proper functioning.

The three wire connectors are for small chassis fans with lower power consumption. the four wire connectors are for processor fans with higher power consumption. a three wire fan connecting to a four pin fan header: note: when connecting a three wire fan to a four pin fan header, the fan is always on; there is no fan control. 4 wire fan in 3 wire mode. 4 wire dc fans can be used in 3 wire mode as long as the design omits speed sensing with the tachometer wire. 4 wire fans have the driving mechanism built into the body of the fan, so the pwm drive line will be required. however, the tachometer line can be eliminated if speed regulation is not needed or desirable.
