All 7990s are reference boards AFAIK so it’s only the bios that may change.
What hashrates do you get from it?
Also worth pointing out, my water loop also has my CPU on it (3930k). ;)

ASUS ARES II and PowerColor AX7990 (Devil 13) were released before reference HD7990. I was getting about 650KH/s per GPU at 1200MHz under Linux with intensity 13. Wanted to try if Windoze allowed to run at higher intensity, but it crapped unexpectedly. When I had powered the machine up after some maintenance, I had noticed a spark and magic smoke coming from somewhere inside. Had smelt my ARES II, pulled it out and removed the back cover.

3 ceramic capacitors molten, 1 cracked, remaining 4 varied in capacitance heavily. Replaced them all. Those missing parts above the failed capacitors must be RC chains to prevent high inrush currents which can damage capacitors. A smart ASUS engineer designed them in and a dumb one supervising the project removed them to save a few cents on a $1500 card. What a shame.
