Nice!

Might also do a "pumping power" on the x-axis, that way you account for restriction in the result. I like seeing both formats, but if you do have highly varying restriction between different blocks the higher restriction blocks "appear" to do better in a "flow rate" x-axis variable chart.

Awesome work as usual. Is there anything on the VRM temps you can capture too? I don't know too much about the card, but I know some blocks are better at VRM cooling than others independently of GPU temp.
