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. The 4 pin computer fan wiring consists of four wires: black, yellow, green, and blue. the black wire is the ground wire, providing the fan with a path to the power supply’s negative terminal. the yellow wire is the 12v power wire, which provides the fan with power from the power supply’s positive terminal. 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.
