Believe me or not but I don't know to set Auto fan speed on this software (5.2.9).

I usually set own Custom Fan profile with 35% fan speed, than I could regoznize difference between my profile and disable fan profile Auto (Fan speed 31%). Now I don't know to move from 35% fan speed. I can increase, decrease, Aggressive or Quite but I don't know to back any more on Auto. Comedy. Little Window Fan Editor no X Button. I remove him with arrow on back.
Auto Button not work any more, I need to remove Precision from Taskbar and than fan back on default speed.
