I'd figure I would share with everyone this unique fan speed controller circuit that I reversed engineered out of PC Power & Cooling computer power supplies. It requires a bit of DC circuit theorem understanding if you want to know why it works the way it does with its delay ramp of the fan under varying temperatures. It is designed to work at 12 volts and can support DC fans that require up to 500 milliamps of current.
