Buzzing in GTX 780?

[Gamer_for_life]

Just now, when I start a game (hitman absolution in this case) my graphics card makes an obvious and quite loud buzzing sound, I'm fairly certain its the card and its never done this before ( recently installed a few weeks ago) Any ideas on what it might be and what i can do to stop it?

I included a video so you can hear the buzzing

It runs at about 50c using MSI afterburner and nothing is touching the fan, also its a reference card.

I couldn't hear anything over the sound of fans. What brand card is it? From experience I can tell you that most of my newer EVGA cards have had a fan that made an off noise that I didn't expect but otherwise worked flawlessly.

Yeah i don't hear anything ether.
Are you talking about the clicking noises at 0:02?

I had a GTX280 which did a similar thing, it could be coil whine. This isn't generally considered to be a defect with the card, it shouldn't affect the way it runs

But it's annoying as hell. My previous PSU has a coil whine problem.
Almost made me go insane
Didn't hear that in the video though.

The microphone might not pick it up depending on the frequency, plus if it's quiet it might not be picked up because of the volume.
