WebMay 5, 2024 · The arduino default is about 490Hz, which you can hear as an annoying whine. You probably want to reprogram timer2 to produce PWM at 31kHz or 62kHz and use that signal. A very-low (eg 5Hz) PWM frequency is little better than 500Hz because each PWM edge is still audible as a click. WebSep 30, 2024 · When the supply drops below about 3.8 V, the fan stops and the tach-out is pulled active-low (the output is of open-collector type). If the fan is spun by hand, the tach remains active-low. The tach-low output is maintained down to a supply voltage of about 0.8 V. Below that threshold, the output goes into an open state.
