[If you remove the blue wire from the fan connector, the fan will spin a full speed all of the time (~3500 rpm). Note that this may shorten the life of the fan, so try it at your own risk.
Well, my first thought was to unplug fan connector from board and put to the fan directly 12V from PSU. But blue wire removing, I guess, would work either )) keeping speed monitoring also
But that's not what I really meant. I was thinking more about some config modifications to adjust PWM values or so.
