When the fan is commanded off, there is a 10% PWM value present (if this pwm goes away, then the fan fail-safes to full speed).
When the fan is commanded to run, on mine it will have a minimum pwm of 25%. If the fan is moving from air through it, that has no effect on the PWM value.
You can test the fan by putting 12v on the Trigger input. That should make it go to full speed after a few second delay.
If you ever find yourself in a fair fight, your tactics suck.
