Fan's RPM displayed as a percentage.

[Tacyon]

As the title suggests .. I'm looking to read out the fan RPM's as percentages of a stated min/max. An average might be helpful to stabilize the display since these values seem to jump around like crazy.

I saw one post where someone asked this and was met with a "Correction" with Ratio and Offset. The response was basically, that was what I was missing with zero mention from either to what to put where and why.

Looking to enter a minimum and maximum fan speed and then get a ### % read out.  How does one go about doing this?

The way it works with correction is for example: if you have a maximum of 5000 RPM for your fan, enter a Ratio of 0.02

This will scale the RPM down to 1/50 of the measured value which would yield to 100 at maximum speed (5000 RPM).

How about a max RPM of 3000 ?    How did you come by .02 for 5000 rpm

I believe it is

100(%)÷5000(RPM)=.02

100(%)÷3000(RPM)=0.3

Cool ... HA!!! See what I did there ?!!
