Controlling 3-pin fans through a PWM signal was an unsolvable problem – until now. Phobya has tackled this problem and now presents an elegant, simple solution with the 4-pin PWM to 3-pin converter.
With the 4-pin PWM to 3-pin transformer, all 3-pin fans can now be controlled with a normal PWM signal. The converter is connected to your motherboard or PWM fan control, while the fans are connected to the converter. Now your 3-pin fan can be controlled like any other PWM fan.
The converter detects the PWM signal and controls the 3-pin fan with the corresponding voltage. This makes controlling your fan simple. The converter is capable of outputting a voltage of 1A, which equals 12W. This means you can use a Y-splitter to control several fans simultaneously through the converter.
