My cards has no coilwhine whatsoever..
Not even in Far Cry 4 with fps over 2000
 
GTX 970 SSC+ x 2

GTX 980 SC ACX 2.0 installed yesterday! I'm happy to say that I can't hear anything at all! Except when benchmarking and getting 3000FPS in low setting tests. Even then it's not really too loud, but it is noticable.
 
I would go berserk if I had to listen to coil whine all the time like some of you guys have to. I feel for you.

Yes I do, on core 15 WU.  EVGA GeForce GTX 970 Superclocked ACX 2.0
Item #:04G-P4-2974-KR
 
Oddly enough this is currently available in the EVGA store atm.  Love the card.

same hear but its tolerable, not as bad as some have been in the past

970 FTW, can be heard from outside the case under 60 fps using a new EVGA 1000W G1 PSU.

Yes
Coil whine,Sometimes soft,sometimes loud.
Came like this straight out the box.

Yes, coil whine on some menus but it doesn't seem to be an issue while under load so its probably not the PSU.  Mainly an issue fixed by fixing a few settings in the game.  Probably an issue regarding high fps on main menus, however most games prevent this (excessive load/rendering).
 
If I had to guess you guys may notice it as its probably a generic problem where the excessive FPS causes unnecessary rendering on something that doesn't require very much processing like a main menu.   I believe 3Dmark has a brief moment where coil whine will show itself when the program first starts loading, but you have to get up to your card and listen to it.  If I enable VSync its fine though.

Common misconception, but no actually. It's not caused by frame rate but by the power being pulled. Why it does this with some games and not others or to more or less of an extent with some isn't something I can answer, but it's not the frame rate itself causing it. The graphics card doesn't care if it's rendering 1 frame or 1,000, but the load put on it is what causes the noise. If this only happened in rare cases like that where it did have an arguably unneeded load from rendering 5,000 FPS at a menu or brand into clip, and to a minor extent where you had to be close or listening for it, that'd be one thing, but it happens to me in Minecraft under 100 FPS, and to anything but a minor extent (it's not just noticeable, it's very displeasureable to play with). It happens in practical use, in many real games, and to a point that it's very distracting, and that is the difference.
 
When I first load a Minecraft world up, I have a much higher frame rate at the onset (since next to none of the worls is loaded in that first instant), and the frame rate understandably drops as the world fully renders out to the render distance. When I first load the world up, I have no coil whine to speak of. Once it loads out, the frame rate drops more and more, yet the also noise starts more and more (and varies/changes as it loads further out even more). If I look straight into the sky, with only the skybox texture being rendered, I get a high frame rate, yet the noise vanishes. If I look level to the horizon, my frame rate drops, and much more is rendered, and the noise shows itself. It's especially bad in Minecraft because as I look around, the noise varies. This is an example of a real distraction in practical use.

Rev 2 ? I Sent out my Card for the 3rd Time EVGA offer to Test it or Send me a New Card with no Coil Whine. New Egg offer me a Full Refund so this is my Last Try.

Nope. I used to on my reference zotac 780ti, it would make the psu whine as well. I used a monster power center with clean power stage 2 and the psu whine stopped because it was getting cleaner power but the card persisted albeit lower. With my new evga gtx980 reference absolutely no whine unless I am in a game menu with vsync off with over 9000 fps...

No
 
Had two 970 FTWs that had minor coil whine.  But now stepped up to FTW+s and now have no coil whine.

Had it pretty bad on my first 970 ftw. Was close to RMA-ing but then my second came in. Ran some heavy benchmarks for long periods of time testing out some oc's. If there was a coil whine I wouldn't have heard it over my noctuas ramping up to 3000. Kinda forgot about it, seems to have subdued quite a bit. Just did a run of 3dmark icestorm. That used to get it going like mad. Still there, yet a lot lot less. Odd. 
 
I guess this is a good thing. 

Yes, a serious very loud coil whine leaking through to speakers even when USB headset is being used.

I have coil whine on both my GTX 980 ACX 2.0 cards.

Negative. Mine seems very quiet, but I'm in my 50s..maybe I just can't hear it anymore?
 
 

No, 980 Ti Hydro Copper.
