GPU problems again...

I don't think i'll be putting anything on the capacitors as I'd be worried that it'd void RMA, it could be the mobo but it correlates with the gpu so the problem is probably still the gpu. Seeming as I can't arrange RMA or anything at the moment my plan was to try and burn in, is it strange for it work perfectly fine while making this sound?

If you do the burn in, then make sure you turn up your gpu fans to 80-100% as the card will run hot with uncapped frame rates etc.

And it's not strange for the card to work just fine while having coil whine. Pretty much all computers have coil whine but not always in the audible range. This comes down to the quality of the components used really.

Ever been to an electrical plant?, notice that buzzing sound?. same deal
Or you know when those camera flashes powers up?, same phenomena again.

There is no such thing as perfect efficient electronics. Some of that energy is lost in heat and vibration thus you get sound as it hits resonant frequencies of the coils.

Would I be able to use the furmark burn in test?

Personally I do not trust furmark and I would never run it.
In the past Furmark could actually do irreversible physical damage due to the obscene stress it could cause cards so nvidia (and I think amd too) put in limiters in the drivers when they detect furmark.

What you want to do is run what ever you have that causes the most coil whine, so I'm thinking that would be a game with uncapped framerate yeah?

Pretty much every game does it regardless of capped frame rate but i'd guess that borderlands 2 is the worst out of my recently played games.

so now the noise is also coming from my PSU, so I tried something for the PSU. Apparently the +12v is the power provided to the gpu and while HW monitor shows 12.0v OCCT which stress tests the PSU shows that i'm getting fluctuations between 11.43v - 11.78v, I don't know if thats typical or not.
