set analogWriteFreq to 220Hz. This was so far the sweetspot for Fan PWM control in combination with a 47µF electrolyt capacitor. If I had a PWM pin free, i would use PWM functionality of pc fans but all pins are in use. So I went with putting a capacitor to the output and regulate the fan speed this way. |
