GTX 580 Whine or Screech Sound

[dominatorx]

Hey Guys
After overclocking my gtx 580 I hear this whining or screeching kind of sound.
I have noticed this when I increase the voltage. The sound starts only when the GPU is on load.

My video card:

Thanks for your help

Check out this thread...

Could my PSU be causing coil whine/buzz in my video card?

I checked out the thread - useful but that sound does not come from my PSU and is way above the recommendation for my GPU.
My GPU needs a minimum 600W and my PSU is a gigabyte 720W.

Coil whine... annoying but it happens. You can put nail polish on the coils to stop it.

The amount of power needed is not relevant in this situation.

I could do that, but does that sound indicate that some components are stressed and could be possibly damaged because i wouldn't want to waste my gtx 580.

Nope. It just happens. Its just a vibration that happens at the right frequencies.

Earthdog can you please give me some more information about this "coil whine" - thanks

By the way this cannot be a capacitor squeal due to more voltage, right?

Coil whine is from the frequencies that the GPU or PSU power section operates at. At some freq, a harmonic is 'just right' for the coil to vibrate at an audible freq. It's uncommon, it happens.

Use a longinsh metal tool that has a insulated shaft or a mechanics stethoscope. Put heatshrink over the long shaft except the tip.

If you can find the noisy coil, get nail polish, cover it.

Cap squeal is from the cap venting usually, a fail waiting to happen.

Or, RMA the card.

Thanks for the info.
But how do i know whether it is a capacitor squeal or a coli whine?

I'm not sure whether i can rma my card although its in the warranty period because, this sound only comes after overclocking and overvolting specially under load
