Color Codes for a 3If you need to install a 3-wire computer fan, forget the wiring diagram. Most computer motherboards come with a standard connector for the fan, and it only fits one way. If the connector fits the pins, it'll work, and you don't have to worry about the pin arrangement.
3However two fans with 3-wire connectors may not have the same wire colors. Thus, instead of using the colors to distinguish the function, better try to study the internal wiring connection. Usually, yellow (or green) color wire is used in a 3-wire fan for the pulse output (tacho) connection.
Wiring 3 or 4 wire computer fans explained 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. ...
Motherboard (CPU) 3 Pin Fan Connector ยท AllPinoutsFans and on-board fan headers are backwards compatible. Proper fan connector placement is shown in the figures below: Fan has a 3-pin power connector; desktop board has a 4-pin fan header: Note: when using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control.

How to Wire a Ceiling Fan To do this method, the wire from your wall circuit to your light has to have 3 wires. Connect black fan wire to the black ceiling wire. Connect the blue wire to the red wire. Connect white wires together. Connect green/copper wires. In the switch box: Split the incoming hot wire into a "Y" and connect it to a terminal on each switch.
Using a 3 wire fan with Arduino? Yes, 2 or 3 wire fans can be controlled using basic PWM. The circuit in the fan detects when the magnet in the motor passes a sensor, and each time it pulls the sense wire to 0V. If you connect a ~10K resistor between this wire and 5V, the wire will be at 5V when the magnet is not detected, so you see a square wave.

Which wire is negative on this PC fan? PC fan pinouts can be found easily online: If you're trying to figure out which wire is ground on the fan itself, and you don't have a connector, then just connect 12V to the middle wire and try ground on either of the outside wires. When the fan spins, you've found it. The other, if connected, is a tachometer.
