Coil whine coming from GPU. PSU at fault?

post #1 of 8
Thread Starter 
Hi there,

I've already posted on EVGA forums but I thought I might get more input here too. So I bought a 1080 GTX from a guy who said didn't have coil whine when he ran unigine valley. Thing is he was using a 4K TV which may have kept his frames lower. My main desktop which I want to use the 1080 GTX for is a 1440p.

I was using a 290x until now which had very little coil whine. I just didn't notice it before because of the water cooling pump which is relatively loud. These are my specs:

  • Mobo: Gigabyte Z68XP UD4
  • CPU: i7 2600K
  • GFX: 1080 GTX
  • Ram: 8gb Corsair
  • PSU: EVGA SuperNOVA G2 750W

My brother has the exact same PSU and so I followed the EVGA tech support guy's instructions to have the bare minimum plugged in and see what happens. These were the results:

Cardboard setup:

CPU: 3930K
MOBO: ASUS Rampage IV Extreme
RAM: 2 x 4GB Corsair Vengeance DDR3
HDD and SSD were also connected.
Monitor was a 144hz monitor.

Tests:
EVGA Supernova G2 750W #1

1080 GTX = Coil Whine even with Vsync on in Witcher 3 game play
970 GTX = Coil Whine even with Vsync on in Witcher 3 game play
290x = Barely noticeable coil whine. Seems like I thought it had no whine but it was probably masked by my loud pump until I tested it today.


EVGA Supernova G2 750W #2
1080 GTX = Coil Whine even with Vsync on in Witcher 3 game play
970 GTX = Coil Whine even with Vsync on in Witcher 3 game play
290x = Barely noticeable coil whine. Seems like I thought it had no whine but it was probably masked by my loud pump until I tested it today.


So right now I'm at a loss. I'm not sure what is wrong but I was leaning to the PSU even though it's only a few months old. Do any of you have any idea of what else to try? I might go to my local PC shop and ask them to try my 1080 and 970 to see if it squeals with a different PSU or is there something else I should try?

Some combinations of PSU´s and video cards just whine when put together and there is no rhyme or reason to it
Only thing you can do is either live with the coil whine or change the PSU or the video card

I have a 750 watt G2 as well and a brand new EVGA GTX 1080 FTW2 and my exact combination does not whine
Any way you can still RAM the GTX 1080?

Yeah it's under warranty and EVGA have already accepted the claim but I didn't want to send off a good card. I'm tempted to go on ahead with the RMA if they follow through with them paying for the courier to pick it up from my place.

Just be aware that the new card may or may not whine as well if you get really unlucky
As i said there is no rhyme or reason with coil whine

Could be the PSU that is causing the whine or it could be the video card
Are you using a 1080P monitor? i am using a 1440P monitor with Nvidia G Sync which might be why i dont have any coil whine.

For these tests it was a 144hz @ 1080p monitor no sync tech and my other main computer where this all started is a 1440p overclocked to 100Hz.

many cards actually whine today

there's a lot of threads for 980ti whining
even the modern 10x0 GTX

if you end up RMA'ing the card for whining you might end up RMA'ing a lot

or maybe you have a stroke of luck

frankly you're already lucky EVGA accepted the claim

I tried to with my 1060, but neither the shop nor the manufacturer accepted a claim (btw the whine got worse after a month, that's outside the window I could've sent the card back no questions asked)


I ended up putting clear nail polish from my wife on the coils, which was the only thing that helped (tried out the usual stuff people recommend, burning the card in, different cables, and even another PSU)


my old GTX 780 didn't whine with my PSU

different cards have different whine noise at different refresh rates/fps

that's why over- or underclocking, changing the power target, and using vsync have some effect on it

you could try overclocking the card, and a higher power target
that could push the whine into a frequency you don't hear any more

which worked only a little for me to be honest

As surprising as it might be it looks like some user report that changing the PSU killed the whine.
http://www.overclock.net/t/1368808/can-a-psu-cause-a-gpu-to-coil-whine

One user from the above thread put some nail polish on the whines. This whine is caused by electric resonance and is present with every coil. If the vibration is within the audible spectrum then you can hear it. Putting something on the coil should lower the frequency. I guess that it might even break the resonance condition to explain why the noise go away.

V-sync reduces the coil whine but it is still as loud if not louder than the motor for the watercooling pump. I might try overclock the card and see how that goes. I wish I did that earlier before removing the waterblock to RMA it because now I have to use the blower.

I might also go talk to my local PC shop and see if he has a PSU lying around in his workshop for me to test.
