I sucessfully built a PWM dimmer, but it required feeding a PWM generator a 5v signal then the PWM generator hooked to the blue wire.
I was like this is way too clunky and ineffcient. I became aware of the NOctua speed controller shortly afterwards and the 25$ I spent on it was well worth it and basically less than what i spent on enough components to build 5 clunky PWM speed controllers
What kind of voltage is that little solar panel producing when not hooked to the fan? What is it putting out when powering the fan?
I've not tried to voltage speed control Noctua's, other than they get what I am feeding the battery.
The silverstones have speed control circuitry controlled by the 10k ohm potentiometer. the potentiometer is not in itself the variable resistor directly reducing the fan speed. That potentiometer can only handle 0.5 watts or so, and likely not for very long.
That 140Mm noctua, when running and upright on a table surface, how wide is the flow? Are there flow 'hotspots' at wide angles or a seemingly more narrow column of air pushed out in front of it?
The Delta fans with the spiral blades on the hub support are awesome at keeping the column of air moved dense and narrow. maKes a great directional fan to aim where needed.
