Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which essentially converts the PWM signal from the motherboard into a phantom thermistor.

PWM helps increase fan longevity, reduces noise, and maintains optimal PC temperatures. PWM stands for Pulse Width Modulation, which is a type of signal used to control electronics. When it comes ...

Implementing another power DAC with an LM317 regulator into a PWM topology but this one adds a preregulator so it can run ...

The system he has come up with is so simple it’s borderline genius. The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then ...
