Hi guys...
as the title says I have this strange electric noise ,and it's coming from my GTX680DC2top.I can't understand why ...Only when gaming the noise occurs...but...no artifacts or issues....and ....it's not the fan...already checked...Temps are ok..
I never overclocked my card,factory default clocks;Latest Nvidia WHQL Drivers;This is the First time I got this problem...
Can anyone help to find what's the problem? It's like a buzzy noise...
I bought this card in 17/January/2013,and I payed a lot of money for this baby...I don't want my card to be defective...
Thanks in advance...

Edit:
I found a very strange behavior.
With V-sync on , the noise is simply disappeared,V-sync off-Noise is there.
Temperatures are OK,For example BF4 on 1080p max details 64 player server max 60°C.
World of Warcraft 40°C,same details...

It is normal?Never happened before!!

Edit 2:
I found a video on youtube ,this case is similar to mine
