Buzzing Noice From GPU When Core Voltage Raised

[alexj900]

When i overclocked my GPU and raised the core voltage, then proceeded to run a demanding game (example: GTA V), my card started to make a buzzing noice, sounds electric sort of
I haven't heard the sound from the card before.

I raised my Core Voltage by +30 mV
My OC settings are in the picture of course.
When running a demanding game my temps are at around 55-60*C.
In case you can't see the picture here is a link to it: https://imgur.com/giKJWno

I just want to know that if anything is bad about the buzzing noice, what it is and/or what i should do.
Oh and by the way, if you have any tips for what i can do with my settings, to increase performance, i would love that. (I'm an overclocking noob)
Thank you!

Its called coil whine, some cards just inherently have it. If everything runs stable you have no problems, it won't cause any damage, just annoy the crap out of you.

Thank you for the answer, guess its nothing to be afraid of
My card doesn't inherently have it though but okay!
I believe everything is stable, I get alot artifacts and driver crasheswhen i go above +150 on Core Clock :/
I hardly notice it with headset though which is positive.

Yeah keep it lower to avoid the artifacts and crashes and youre ok.

While most GPU manufacturers won't accept it for an exchange for this, if you did, another card likely would not make this noise.
