This. Or a grounding issue. More than likely the former. I'm assuming the speakers don't whine in a different device?

I also think the noise is electrical interference, which is why you'd be able to hear it through your speakers.

can you induce capacitor whine? Would my UPS being a pure sine wave unit have messed with them? I can't understand why both of the cards do this

No, noisy capacitors mean they're about to blow.


Do you have a multi-meter handy?


The fact that the noise is increased when more power is drawn, means we got an electrical fault somewhere. It's gonna be a real PITA to figure out what, but can't go down without us fighting right?

So first things first, start touching stuff, specifically on the GPU. Make sure you are as idle as a sailboat. Is anything specifically warmer?

And to verify, 6950,6950,5770 all whine?

We're caseless at this point, correct?

nothing warm; with two 69CFM fans are on max blast, i only get to 62 C on furmark

two 5770s and the 6950 whine, leading me to believe either the UPS sine wave / EMI filter or magnet fans did it

I have a multimeter handy also, but I'm on one of the 5770s now and my 6950 has to get put back together

i'd have to disagree with you here. the EVGA 780i and 680i motherboard also have this with some of the motherboards and the ones that chose not to RMA it didn't have any performance issues nor did they blow.

there are a few threads i am sure about this issue and might be of help. i might be wrong by saying they are not ready to blow but am almost certain they will not.

maybe there be more knowledge from other users that can chime it.

Let's check all your voltages. Including the 3.3v (orange wire on the 24p ATX) Remove all fans. We gotta get this thing hot. Then we start touching. Nothing is going to overheat, but if you find specific circuitry which is actually painful to touch, we'll be onto something. I'm not talking about oops that's hot, it's going to have to really hurt.


^You know what I was getting at -_-

edit* btw... evga told me the same thing that the noise wouldn't bother performance so no rma needed. what i did then was requested a rma anyways and gave a different issue. sucks to have ta like but the noise is not acceptable.

That's what i meant I've seen people making DIY guides about changing them somewhere.
It might have been on here even, might be worth a shot.

nothing too hot without fans and no artifacting, and the voltages are in spec according to bios and according to the guys that RMA'd it back to me with a "tested" sticker on it

still get the lighter squeal on windows 8 installed to a thumbstick. Furmark wouldn't start, but let's assume it would've made the OTHER sound wink.gif
