With my Strix 2080 Ti OC, it has horrible coil whine under load. If I lock it at 30 FPS, you can't hear it at all. At 60 FPS, its slightly noticeable, but at 180 and higher, its very loud and quite annoying.
For the guys saying their cards are quiet, at what resolution and FPS are you gaming at? I'm running two Asus Swift 240hz 1080p panels.
I bought one Strix card on Amazon and sent it back due to the coil whine. I bought a replacement at Microcenter and its just as loud. I may try returning it, but IDK if it would be any better.
