However 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.

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.
