allright sir i'll wait for the other graph's then :D

The 3rd element RPM would better represent which one has the engineering edge.

but how accurately is the onboard RPM monitor? anything below <800 RPM is not picked up correctly either.

I have recorded the RPM values, and will include them in the roundup somewhere, but in the graph they would quite fit due to different scale. Sometimes less is more:)

it seems I bought the right fans :) nexus is one of the more silent one's :)
