4 Wire Pc Fan Electroschematics 3. fan spinning at high speed: if your 4 wire computer fan is spinning at high speed constantly, it may indicate an issue with the fan’s speed control. check the fan’s wiring connections and make sure they are properly connected. test the fan in a different system if possible to rule out any compatibility issues. 4. 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.

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 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. Ignoring the colors for a moment, the pins (hole) have these functions: pin # 1 ground (normally black) pin # 2 12 vdc fixed voltage on a 4 pin fan system (normally yellow, sometimes red) pin # 3 speed pulse signals from motor to mobo (normally green, sometimes yellow).

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. Here are the steps to wire a computer fan with standard wiring: identify the wires: before starting the wiring process, it is essential to identify the fan’s power, ground, and tachometer wires. the power wire is usually red or yellow, the ground wire is black, and the tachometer wire is blue or green.
