My first 1070 FTW had absolutely horrible coil whine. I have a EVGA G2 750 power supply. I even tried it with another power supply, same thing. I RMA'd the card and I am happy to report that the new card has zero coil whine. :) 

Thats... oddly disappointing to hear. I have the same evga g2 except the 550watt myself, and my replacement had the same level of noise, but I doubt id get another replacement, and definitely dont want to play the lottery and end up getting another card with the same noise... 

Hey guys, just wanted to update you all.
I revived my replacement 1080 ftw today and I'm happy to report the coil whine noise has drastically decreased. There is still some coil whine present, however I have to get right up to my case to hear it and my case is under my desk (previous card I could hear from under my desk). Overall I'm very happy with Evga and their rma process. 
 
Still using my new Evga G2 850w.

Hi all OP here.. i said id update and here i am.
Put the FTW in bout 5 hrs ago,ive done plenty of benchmark tests (Firestrike,Valley and Heaven Benchmark 4.0) and im very impressed.
Coil whine yes i do have it but..its very,very slight,i only have it in GPU intensive stuff benchmarks, GTA V,Witcher 3 etc ..and im only on a Corsair TX650 PSU.
Boosted to 1987Mhz without touching anything. after a slight OC +40 on the core clock and +45 on the memory clock ,and a custom fan profile it boosts to 2025 and 4050 on the mem.
I haven,t even touched the power limit. Eats games for breakfast runs everything beautifully on my U2715H Dell 2k ultrasharp. I7 4790K cpu
Anyway to cut a long story short im very very happy with this card..it oozes class. The packaging,the folder that comes with it with your bits and bobs in ..everything just looks so good.
This is my 1st EVGA card..it wont be my last, im seriously looking at upgrading my warranty already!! just to stay with this company. A few Pics of benchmarks if thats ok.
 
 
 
Ive received so much helpful advice on my questions from forum members and also EVGA staff. For that i thank you all.
EVGA you,ve a customer for life..
All the very best

I've researched the coil whine topic before deciding to get a 1070 myself, many users mentioned that a high quality PSU will likely fix coil whine. All of the user feedback (who obtained a better PSU after those suggestions) reported back saying that it fixed their coil whine. I have a Corsair CX750M (probably not a recommended PSU) and the only time I experienced coil whine was at the ending splash screen of Heaven benchmark after finishing a benchmark. I think I remember that you mentioned using a Corsair TX650 and if you are still on that, you could try a premium PSU.

Nice one j0NOX,really pleased for you pal so glad you new card is much better.

Nice findings ianfinity ..yep still got my tx650 and tbh my coil whine is still very very slight,the only time I heard it more considerably is when my lad sticks Lego hobbit on and it jumped to over 500 FPS haha..I capped the FPS and its fine after. I actually have it at +55 and +550 on the respective cores and I still only hear very slight whine,certainly nothing for me to moan about. Next psu il go for a higher model and see if it eliminates it completely..cheers pal

Wow, my new rma card is now having the same problems that others are having in this thread.

Looks like I'll be getting a full refund and talking my business elsewhere.

If you have coilwhine and replacement has coilwhine then probably either other hardware like psu being cause due bad ripple or you set standards to high, if its as loud as exiting heaven benchmark all the time then i would be worried though.

Look at the other post.  That isn't a problem with coil whine, it is black screens and fan problems.

Yes i know, my new RMA card has black screen and 100% fan prob. I just wanted to update people, happy the coil has reduced but it looks like this card a new problem.

I tested/replaced a few things like the PSU before my first RMA and still had coil.. Currently using my brand new G2 850w.
