UPDATE: I completly cured the coil whine by reassemble the card WITHOUT the back plate.. it was the culprint!
 
Its reduced 90-95% to a normal very faint non noticeable level in case...

My GTX 970 had a bit loud Coil Whine from day one till today (3 and half years after). Frankly if i didn't use haedphones, i would had it already replaced. In my old pc even motherboard Coil Whines depending the music playing in the bagkround whenever is Realtek on board or NVidia's card HDMI audio.

Oh, i am sorry. Has* is the correct, my bad. Nothing stops it. Neither another motherboard nor other PSU (I have changed 3 PSU's for other reasons all these years). Not even the pinch of noise changed a bit.

I also tried two high end PSUs and two diffrenct GFX (2080 Ti) both same noise.. nothing changed so I don't believe in this PSU trick many writes about.. However I do believe people fixed their coil whine with new PSU, but then it was because it was actually emitting from the PSU and not GFX. And people thought it was from GFX.
 
I never had CW before.. And I do believe EVERY 2080 Ti suffers from it due to design. I still have it, even though it can be reduced with removing back plate if water cooled and have a good pc case. Mine is a ok silecener. DB Pro 900 - Be Quiet

The same was said for 900 series. I have a supposedly higher quality board design (FTW) and a friend with a cheap blower type model doesn't. Even my ASIC quality is so bad that i can't OC even a bit cause i have crashes in some games like Witcher 3. It's totally random and the only other way except applying a frame cap to me is to heavily power limit the card with unlinked power to temp ratio.

I had a 980 GTX and 1080 GTX none had whine.. But I heard a lot have 970 and 1080 Ti with whine.
 
Its just a annoying issue to have when you paid premium price for the 2080 ti.. here in europe its close to what equals to 1800 dollars.. which I paid for raw performance but also raw noise.
 
ASIC what is that? your cooler?  I always run water.. nice and quiet and OC as high chip or pwe limit would allow.

I noticed that sometimes increasing the voltage by a few bits in EVGA XOC helps.
Other times it's actually the fans (where 2 or more fans, are in sync with one another, generating a higher pitch sound or whine). It often is more audible above 75% of fan speed; and oftentimes lowering one or two of the fan speed, solves that.
Or, it could be one of the fans is actually touching something, like a cable or something, that's causing the sound..
 
Sometimes it's the capacitors. They swell and shrink with electric voltage. It's only a tiny bit.
But larger size capacitors being 'filled' and 'emptied' several thousands of times per second, can make them 'sing'.
They literally buzz, creak, or have a high pitched tone, depending on their charge and discharge frequency.

I just received an RMA replacement SuperNova 1300 G+ for a Defective (bad fan) 1000 P2 yesterday and it has coil whine I can hear sitting in my chair at my desk as soon as a game load. The p2 was dead silent but this G+ squeals like a pig once a game is loaded. I did all the usual listening around the case and the GPU is silent, Mobo VRM is silent but as soon as I get up behind the PSU and listen at the back the squeal is evident. I am having crap luck with EVGA power supplies as of late. So here we go with another service request and RMA along with another couple of weeks(if i'm lucky) for a replacement ;-/
