GTX 1080 FE, coil whine?

Hey folks,

Bit over a month ago, I bought an EVGA GTX 1080 FE, and it's been running flawlessly.
Have played both Witcher 3 and Fallout 4 with no hitches, among others.

Then, when Deus Ex Mankind Divided released, I played that, too, and things were running fine there aswell - 60 - 70 FPS at Very High settings.
However, last night I noticed slight flickering on some textures during conversations in Deus Ex MD (might always have been there), so exited and checked after I verified it wasn't just the lighting in-game, and noticed that my GPU had reached 87°C for the first time (usually reaches 83°C max). I started Deus Ex up again, and I noticed my GPU was making a whirring, slightly high-pitched sound.
Checked around afterward, and I can only hear it in Deus Ex and Witcher 3 - not Fallout 4, Planetside 2, or No Man's Sky.

I was under the impression that it would be present all the time if it had coil whine, and find it a bit odd that I hadn't noticed it up until then. Granted, it's not super audible even at the worst of times - so I might just have been ignorant of it up until now.

So I'm left wondering, does that sound like the noise being due to coil whine? - the audio print is somewhat akin to the sound a television might produce, just for reference.
Is it possible it's only caused under certain conditions?

If so, I reckon there's not much I can do about it - correct - other than try to avoid those conditions? ;o



Edit:
Did a quick test in Deus Ex - the sound remains even if I set the overall quality to "Low", BUT, only as long as the FPS is unlocked (going at 170FPS), when I lock it to 60FPS the noise disappears. Still a bit odd that it only occurs in Deus Ex and Witcher 3, though. :S
In actuality, it seems to not be present so long as the FPS is locked at 60, regardless of settings.

For reference, No Man's Sky wasn't locked at a certain FPS setting, and did not produce the noise.

Probably. My gpu seems to only whine when vsync is off the framerate is over 60fps and gpu load is pegged at 100%, usually it won't happen under 60fps even if the gpu is under 100% load for whatever reason. But yeah a lot of times coil whine isn't very consistent, from my understanding coil whine is happens when the gpu hits a resonant frequency where the coils or inductors start to vibrate, like someone breaking a wine glass with their voice once your voice hits a certain frequency the glass will vibrate and break. So it could be that witcher 3 and deus ex (both very intense games for a gpu at higher settings) causes this vibration to occur where it other games it just never hits that frequency (im not talking about the frequency of the gpu core clock just to make that clear). So yes it absolutely possible it is only caused under certain conditions, in fact that's likely usually gpu's won't whine at all times under any load. I wouldn't worry about it, my old 760 has been whining for years and it still works great, as long as the noise doesn't bother you I wouldn't worry about it too much.

Deus Ex strikes again, haha. Yeah i wouldn't worry much about it certain games tend to cause GPU coil whine on high frame rates i would just cap the FPS to 60 by enabling v sync or whatever method you would like to use :) should help with coil whine/temps

Cheers - and am I correct in my understanding that there's little that can be done about it; short of getting an RMA, but even then I'd have trouble convincing them it's sufficient grounds for one? At best I could hope for it going away with time.

Also, it's primarily (if not purely) a cosmetic issue, correct? It won't cause any harm to the GPU or any other component eventually? :)

Sorry for the rather amateur-level questions, by the by.

Hehe, cheers for putting up with my paranoiac questions, folks. Very much appreciated. :)

@Dunlop078: Ah, cheers for the explanation - was somewhat aware of it being due to harmonization in vibrating components. Wasn't aware though that it could eventually fade after a while; I assume you mean in the same way that a TVs coil whine might fade a bit as the set warms up/what not. :)

@Aladdad: Indeed. Games' been running rather well otherwise, though - as did No Man's Sky - suppose I'm lucky when it comes to optimization, but apparently not so much when it comes to components ;)
And luckily I tend to try to stay on the 60FPS dot - DE:MD simply didn't lock the FPS unless v-sync was enabled, which in return caused input lag (ever so slightly). But it appears nVidia Inspector released a profile recently, so can lock it through that - couldn't find it the other day, and global settings didn't do the job.

@WildCard999: Ah, good to hear it won't do any harm. Was under the impression most outlets didn't accept coil whine as a legitimate RMA reason - especially a month or two after purchase.
But, all things considered, the fact that I hadn't noticed it up until now despite 10 hours in DE:MD, a good 100 in FO4, a few in Witcher 3, and various others, would seem to point towards it not being that big of a deal. :)
Here's hoping becoming aware of it won't increase awareness of it ;P
