Added a water pressure gauge, as I like an instant readout on the impeller and cooling performance. Turns out that I "missed" a few RPMs in the range whilst taking the picture, but otherwise the comparison of water pressure PSI vs RPMs plotted pretty much dead nuts on straight line using an Excel linear progression.
Just a few sample picture shown, not all taken. Those in blue text on the chart are confirmed values, vs the red ones that were plotted by the linear progression.
