Any change of PWM settings must be explicitly triggered by software (see below). Change PWM Duty Cycle Using Software ¶ To set the duty cycle, use the dedicated function ledc_set_duty (). After that, call ledc_update_duty () to activate the changes.The fans I tested with the ESP32 still spun at 0% and up to about 20-30% the speed did not change. After 20-30% and up to 100% it acted normally. I looked up a random Noctua PWM fan and it said min speed was 450 RPM at 20% PWM. It did not say whether it stayed at 450 rpm with duty cycles from 0 to 20 but I would not be surprised if it did. gang bang the deans wife slutload
