Graphic card makes fizzing noise under load

[madindehead]

Hey guys,

So, I just put my PC on water today and I.still have the side panel off. When I went to run MSI Kombuster, my GPU starting making a weird fizzing. I have never heard it before, but then again, the fan has always been so noisy. There are no leaks on the GPU block. Could it just be the capacitors on the GPU, I know they sometimes make weird noises.

Just to add, as soon as I stop the stress test, the noise stops.

It sounds like the famous coil whine you go there. you mite have knock it when install the waterblock. There is nothing to worry about.
If you can fine out one is making the noise you can use some glue on it to stop it.

 

[madindehead]

Yeah, definitely seems like that. It's perfectly fine when not under load, no noise at all. Everything is leak tested, so must just be whine I couldn't hear before over the insane fan on it.

i had it my cards (6950, gtx 480 and gtx 580) all of them watercooled but when i got a new PSU it stop on my 580, what PSU have you got and what version 480 have you got?

 

[madindehead]

Zotac GTX 480, and a Corsair HX1000.

Only whines under Kombuster, and not gaming from what I've noticed so far.

I've had a couple of cards with this, it's coil whine as said above.

 

[madindehead]

Cool. Like I said, I probably never heard it before because of the fan noise Just wanted to be sure Does only happen when it's on 100% load like with Kombustor, so I'm not hugely worried

 

[Sgt Tackleberry]

Yes mine only did it when it was under load, but it's nothing to worry about.

Kombuster is at a few hundred FPS, which most capacitors squeel at when its going that quick. If you ran kombuster with vsync forced on (pointless for temps, but good to test this theory) it most likely won't do it anymore.

My 6950 does it under Furmark, as said it's nothing to worry about
