@p1ngb4ck said in Max PWM Value for temp controlled chamber fan?:

e.g. the temperature control only switches the fan on and off, but not with different fan speeds?

The PWM signal is switched on the negative side, so it should still work even with the positive side being fed by the buck converter.

As your machine has an AC mains bed heater, I suggest you upgrade it to 24V. This may increase the travel speeds you can achieve too.
