Compared to the experiences shared here, they have definitely changed the way the voltage is read in the new ones. Actually, I do not trust the new reading in the UI at all. For one, it is all over the place. I started the miner up with my supply set at 11.7V at the multimeter and immediately was getting 12.5V in the GUI

I'm not certain yet, but it appears that when the fan RPM goes up the voltage reads lower in the UI.
For my own sanity check, what hash rate should I expect on a version 2 at 12.2V?
