Of course all you need is the red and black wire to run your computer fan but if you didn t know what the extra wires are for this video may help you out.

Circuit 3 wire computer fan wiring diagram. With the help of this third wire a. It shows the components of the circuit as streamlined forms and also the power and signal links between the gadgets. The fourth wire connects to a circuit on the main board that s used to control the fan with precision. Extra consumer same as 87 recommended wire sizes.

The ins and outs of a 4 wire computer fan. This is ac power and not a dual capacitor so the. Ground completes circuit 87. Or in an 84 to 89 240 you may use the a c power on wire.

12v switched wire to green wire at a c clutch. The third wire comes directly from the output of the built in hall sensor chip generates output pulses during the fan rotation. With the help of this third wire a monitoring circuit can see the rotation. I ll provide a diagram and explain the wires below.

The difference between 2 wire fans and 3 wire fans is the availability of feedback from the fan for closed loop speed control. A wiring diagram is a simple graph of the physical connections and physical format of an electrical system or circuit. Assortment of 3 way fan switch wiring diagram.
