GPU Coil Whine?

[LAGman91]

So here is a strange issue with my GPU, I own a GTX 1080 Ti and I have it overclocked on 2GHz 1Volt. I use it to game at either high FPS 1080p OR 4k/2k 60fps. In both instances my GPU usage is at 100% but at 4K in some games it makes a strange noise I believe to be Coil whine. In some games strangely the coil whine goes away by disabling V-sync rather than enabling it. How is that possible? For example on NFS heat at 2k resolution I get 90 fps without V-sync without coil whine but when I limit my fps with V-sync at 60 it does it, why?

Coil whine is a normal byproduct of computer hardware operation. Ignore it

Don't worry, coil whine is normal. In my PC I had A different pitch of the coil wine depending on how fast I moved my mouse in game, so when it happens and how loud it is will be dependent on many different factors. As long as it isn't too loud or annoying just don't pay attention to it.

I know it is normal, I am asking why it is happening more when I LIMIT GPU usage.

Now that is odd. I will say, that I know alot of people are saying coil whine CANNOT be fixed. However, most high end PSUs you'll see normally have some form of adhesive solid near the coils to lessen the effects of coil whine ( sometimes this adhesive melts unfortunately and can cause a mess although it can be maintained. ) so theoretically if you do the same to GPU coils or even VRM coils it should reduce coil whine. Probably not eliminate it, but once again, at the very least lessen the noise. Even though that isn't your main question. Just an idea. Concerning when you limit GPU usage, it produces more coil whine. As far as I'm concerned that is unheard of. Usually coil whine happens when framerates get high and it goes full power ( you could also limit your GPU power theoretically to reduce coil whine ), but I have never heard of it becoming more apparent when GPU usage has been limited. Are you sure it is coil whine, noise wise?

99% sure as I have played around with the general system draw but it only happens on the GPU at these specific situations.

Coil whine is a physical resonance of the GPU components. It may be in the case of your hardware that resonance exists at a different load point. Even under 99-100 percent utilization the TYPE of load can also influence it. My GPU doesn't really have whine while gaming, but does when running F@H. Both are 95+ percent loads, but stress the GPU differently.
