Option to "calibrate" Y-Axis in fan editor
In reality custom fan curve is being set in % values, not in RPM. Y-Axis in fan editor is for a indication only.
By default app would assume 100% = 5600RPM and update it to higher values if it sees your fan actually going faster.
Now you can manually click Calibrate
button in Fans+Power, that would run a quick process of calibration when app would try to set maximum fan speed to all fans, measure them and update Axis accordingly
Important notice : actual fan behavior is not affected anyhow! It's just to show more accurate RPMs in the editor :)
