I have the same issues, however they just occurred recently. My card, a G1970, suffers from extreme loud coil whine. I was able to deal with the problem by downloading a program called Nvidia Inspector and limiting the frame output of the card to 60 fps. It's silent now and I am now wondering if, by limiting the frames, I am also limiting the power that the card draws from the PSU, which at the same time is reducing the coil whine of the card? If this is the issue, is the coil whine of the card caused by a PSU which can't deliver enough power during load times, or stable power? Would love to get an answer to these questions by someone from Gigabyte, as I am considering RMA'ing the damn thing. However that is something I want to avoid doing, mainly because I am currently situated in Japan.
