Cpu Fan Wire Colors 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. In this article, we will delve into the basics of a 3 pin fan wiring diagram and explore how it works. a 3 pin fan is a type of cooling fan commonly used in computers. it consists of three wires: the positive ( ) wire, the negative ( ) wire, and the sensor wire. the positive wire supplies power to the fan, while the negative wire is connected. The wiring of case fans typically consists of two wires, a positive wire (red or yellow) and a negative wire (black). these fans are usually connected directly to the motherboard using a fan header. 2. cpu fans. cpu fans are specifically designed to cool down the central processing unit (cpu) of a computer. 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.

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. 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.
