@undeadpolice My theory is different, i think this XFX 390x bios from netkas, is not designed for reference cards. I guess he is from some custom PCB card. That's why VRM are hotter on this bios, cards are less stable and voltage readings are not accurate. 20c difference between VRM temps isn't normal. This is way too much. Also look at "VDDC power in" and "VDDC power out" readings. @PieEyedPiper Don't look at 12v readings at gpu -z, they are very not accurate. But yes, 12v drop to 11.38 only on 390x bios. In my opinion better stay with Hawaii bios until we get more info about new cards.
