So as the title says I've an issue with my GTX 1080 O8G GDDRX5
While playing games (even when fans aren't spinning i can hear a weird buzzing noise)
No problem with FPS so far
BF1 @ Ultra runs @ 144 FPS Even with this sound.
And all the other games running perfectly, just the noise that is damn annoying (can't hear it when gaming tho due to sound of the monitor)
Is it any issue?
Should i send it back?
Thank you very much for any help given.

Actually I have one last question.
It seems like my GPU do not post for the first cool boot.
When I restart the pc it boots perfectly.
Any ideas what would be the issue?
Thanks
