It is strange, usually coil wine comes with high FPS. If you decrease resolution, FPS should go up and so the coil wine.
On the other hand, the load on the PSU may decrease as the GPU must be less busy and drain less power.
I don't know where it comes from, but that seems a bit contradictory to me with the GPU fault hypothesis.
yea it’s my gpu... just never used to whine. Might be either the psu or the fact that I put the accelero on and took off all those stock plates and thermal pads and now everything is out in the open. But I did notice the whine is less when I reduce the FPS or power draw. I undervolted it last night and it reduced the noise by like 40% .... when I change the resolution from 1440p to 1080p it goes awayI'd think it'd be the GPU, too. Mine (GTX 1060) used to do that too when doing something more demanding. For example, playing high quality anime files with madVR filters enabled. The whine would stop when the video was paused. Come to think of it, I haven't heard it in a long while but I do have an SF450 so it might have been the source, as my SF450 does have other problems, as well (clicking, noisy fan).
