Just an update, tested it with the UNIGINE Valley Benchmark (EXTREME HD) preset, during the actual graphic benchmark, don't discern any coil whine (sometimes, it hits 120-150 FPS). Nevertheless, when one actually tries to quit the app (menu), the screen/display that sticks around for six seconds makes the card coil whine. (27, or 28 seconds into the vid).
It sounds a lot worst on the recording than in person though. If I configure the FRTC then there is no discernible coil whine at all. I'm gonna keep the card, as long as there's a way to re-mediate the problem - pretty much won't be trying to get past 90 fps anyways (VR).
