Aorus gtx1080ti extreme 11g weird noise

Problem is that I can't tell where the sound is coming from, thanks for the video either way, it does help.

If you go into afterburner/XOC, and manually turn the fans down, does the noise still exist?

FYI, the latest GeForce patch (397.64) has been a bit wonky. I did have a very minor issue with my 1080 with performance, but after doing a clean installation of 397.64, I got all my performance back.
