So I just built a new computer, and after multiple tests it seems I'm getting coil whine coming from my new Gigabyte Ghz Edition 7970.
Here's what I've done:
1. Swapped out current HX650 PSU for my previous TX750 (which was silent) --> Coil whine was still present
2. Swapped out new 7970 for previous GTX 260 (which is usually silent other than fan) --> Coil whine was much quieter (only audible with side panel off and with ear near case)
3. Put my 7970 into my brother's computer (which is normally silent) --> same coil whine coming from 7970
4. Put my brother's 5870 into my computer --> very quiet coil whine/not noticeable under normal conditions
As a result, I'm thinking that while the coil whine is louder in my 7970, it's due to an interaction between my mobo and GPU. I have a bad feeling that even if I RMA this 7970 and get a new one, I'll still get the coil whine; the only other thing I can think to do is just run without a GPU and use the Intel HD 4000 graphics and see if I hear anything (but at this point I'm pretty confident it's the GPU).
Should I just stick with this card? I've already had an RMA approved through newegg but I'm not sure if I should go through with it. It's just frustrating having built an entirely new PC that runs great but whenever I boot up a game I get coil whine.
