    Yes! I did no print until now, but 244Hz makes PWM usable with my pump !
    The pump starts with S50 and i have good flow between S100 to S255.

    Maybe 500 would be even better, but also with 244 the "pulsing" is gone, so i can use it.

    THANK YOU !

    News: a 220uF capacitor works for 3 fans in parallel.
    Scope image is quite rough and strange, but the fans start from 15%.
