This is example with the same noise on Asus Strix 780, listen:

Somebody comment:"looks like the right fan has bearing problem" in comments.
Is this ok or something is bad?
Look at the end of video or at beggining. There is definitelly some rattling noise when card cooling down.
Thats like the only noise I can hear in that video, maybe you should make and upload your own video?
Or if its not your fans its likely coil whine and that is not uncommon.
OP maybe you should follow this advice and make your own video.
Failing that perhaps a Don can close this thread and all future ones as this is getting silly.
