Do you need a case fan controller?
You don’t need a fan controller though, you can get a 3 or 4 pin fan splitter to connect two fans to a single fan header.
How do you control a 4 wire fan?
Sense (tachometer/tacho) delivers two pulses per revolution of fan. Tacho output is an open-collector output thence requires one external pull-up resistor. Control (PWM) is the input for PWM pulses….4-wire fans explained.
| PIN | WIRE COLOR | FUNCTION |
|---|---|---|
| 1 | Black | GND (0V) |
| 2 | Yellow | +12V |
| 3 | Green | Sense/Tach |
| 4 | Blue | Control/PWM |
How do you control the speed of a 4 wire computer fan?
In addition to the power, ground, and tach signal, 4-wire fans have a PWM input, which is used to control the speed of the fan. Instead of switching the power to the entire fan on and off, only the power to the drive coils is switched, making the tach information available continuously.

Is it possible to control 230v 50Hz operated fan how?
The proper way to control dimming 230v AC is through phase control with a Triac: the Triac then is fully opened, but only during a part of the sinus AC wave. But controlling an AC load is not as easy as controlling a DC load. The AC mains with a sinusoidal wave has a frequency of 50Hz.
What is a 4-pin fan?
A four pin connector is a little different than the three pin connector since it has the extra (fourth) wire used for controlling and sending signals to the fan, which likely has a chip on it that tells it to slow down or speed up (in addition to the other wires the three pin connector has).
