I've researched before and found that my coil whine on my 970 could be resolved by slightly OC'ing the voltage on it. I can't figure out what software I need to do this. Please give me some guidance. I'm looking forward to the new Diablo 3 2.3 patch, but the last time I played diablo 3 with the card, the coil whine was substancially worse. Thanks for the help!
