I want to low pass the signal to the fans in this circuit.
PWM frequency is 35khz and I calculated that I would need C = 10 µF and R = 10 Ω
But no matter how I place my capacitor and resistor, I get 12 volts and loose the PWM.
I basically tried a lot of options, I just give up 🙂
EDIT: here's what I tried (but I get 12v on the fan):
