I got a PowerWalker VFI 2000 RT HID that is running under minimal load (5-10%), but its so noisy I can hear it two rooms apart. I see in the spec sheets it say always on, and adjustable fan speed, but I cant for the life in me figure out how to turn down the fan speed or see any options to change it. Anyone got some knowledge about it?

If not, has anyone tried to change the fans or control them somehow else? Its not too fun having a jetplane running. If anyone have done the fan change I was thinking swapping with noctura or other high quality fans. I remember Papst was the big deal before to push much air with low sound, but not sure now so if anyone done this I would love to hear it.

Of course the best would be if it would be possible to enable the auto fan speed so it can calm down
