Where is my coil-whine coming from?

[Denoxx]

Hey guys

 

I now got my GTX 780 for a while and I noticed that when I'm doing some Folding@Home, "something" in my case is starting to whine. First I thought it was the PSU but I wasn't. Im thinking that its my graphics card, BUT the strange thing is, that it only whines when I'm folding and NOT when I'm torturing it with something like FurMark or any other benchmark. 

Could it be something different from the GPU? Maybe my mainboard? I thought of RMA the graphics card but I have to be sure that it really is the cause of these noises. What could it else be?

 

Thanks for your answers!

It's your GPU, mine does the exact same thing.

It might be the motherboard. Have you tried to stress test the CPu to see if thats it? Also I don't think coil whine is reason enough to do a RMA. Technically the part is not broken

More than likely it's the PSU.  Since it's so high pitched it's often hard to tell, but that would be my bet.

I tried running Furmark + Prime95. No sounds at all, despite the loud fans I also wrote the Asus ( my GPU is from Asus) Support and  they told me that I could RMA it for coil whine (but for that it has to be the GPU that is acutally whining)

Hm no I dont really believe in the PSU anymore. When I open my case the sounds definitely coming from somewhere around the GPU. I also replaced the PSU with a Corsair AX860i Platinum

Gotcha. Ir's just that RMA is not always possible with coil whine. And if it isn't the CPU power delivery, then it's most likely the GPU

It's probably either the chipset fan or the GPU.

It cant be any fan. I've turned up each fan for its own to max and there was no sound at all

Then its the GPU. But that's weird that it only whines when Folding.

You could try taking your gpu out and run folding with the onboard one to be sure it's the gpu
