7970 Coil Whine RMA?

oh and another thing can someone please point out - show a pic or photo of where the coil is located on their GPU. :rolleyes:....

..... this may help you understand whats going on..http://en.wikipedia.org/wiki/Coil_noise

What is happening more and more with the current gen of Vid Cards is that they are causing the coils within PSUs to resonate closer to the human audible range. Its always been there. Some PSUs do a better job of dampening it others don't. The fact that u can get lucky with replacing the GFX card is only disguising the problem that lies within the PSU. Not every Vid card will draw the exact same power therefore it can appear that changing the video card works. It doesn't the fact is that all that happened was you put a card in that lowered that frequency below ur range. It has nothing to do with the wattage of the PSU rather how the PSU coil has been designed and dampened.

For those interested, the application of a dab of glue onto the coil fixes the problem as it changes the resonating properties of the coil. You will see more and more PSUs come out with figure of eight coils as this helps immensely. Oh the application of glue will ofc void any warranty.

FYI -

I run both a Silverstone Strider 1500W and an XFX Black 1250W. Both are good quality units. All my cards whine, how much and how loud depends on frame rate and overclock.

As was my PSU. Fact is tho, replacing it stopped the whine on mine.

Well replacing the 7970 with my old GTX 580 fixes it on mine, the noise is definitely eminating from the card.

Look around the internet there are lots of 7970 users reporting the same with a variety of PSU's, it's the capacitors.

Yeh it's definitely not always the psu. I tried out a 7970 prior to my 680 and that also had significant coil whine on both of the psus I own.

9 times out of 10 it will be the increased load on the PSU which will make the card sing, quality make or not.

and yet lots of people have RMA'd their 7970 and the replacement hasn't done it, so obviously in the 7970 case it is not 9 out of 10 the PSU.

Please just read the internet before blaming peoples PSU's and suggesting they buy a new one.

google gigabyte squeal

https://www.google.co.uk/search?hl=en&source=hp&q=gigabyte squeal

pretty common issue,either gpu or psu,deffinatly one of those two or a combo of both,can also be driver related also

just wanna add for me switching psu fixed the noise,thats using a 5770 and a 5870

Ha, quality reply. Source for 'lots of people' actually getting non whiney RMA replacements plz?

It really is most likely to be the PSU.
 
There's no definitive answer that covers every case.

For some it's entirely down to the PSU and they'll get squeal with whatever graphics card they use.

For some it's entirely down to the graphics card and they'll get squeal whatever PSU they use.

For some it's a particular combination of graphics card and PSU.

Going back to the OP he has the opportunity to return the graphics card and could perhaps swap it for a different make, model or even get something entirely different.

That would seem the best option to try initially as I assume he can't swap his PSU for little cost.

If he still gets squeal with the replacement graphics card then he'll have to consider if it's worth swapping the PSU.
 
same

Hi guys,

just wanted to revive this topic a little bit since I`m having same kind of trouble.
No v-sync tweaking in games helped. Even borrowed new Seasonic SS-1000XP 80Plus Platinum 1000W Retail PSU, swapped it for my corsair and it didn`t helped. So no PSU problem seems.
RMA`d it for first time, was denied, no issue found, service said, well issue is there so sent it back again.
Also posted a ticket on Sapphire support website. No response from them so far.
So probably will try to go non standard way about it if they find no issue again.
But 420 euros for a squeaking GPU, not a best deal to me.
So will see.

(didn`t buy it from ocuk)
 
My 7970 whines quite a bit, although I will see if it's coming from the psu or gfx card later.

I would say it's the loudest thing in my case, but that goes to the sea gate 2tb hdd as when it spins up it sounds like a 10,000rpm fan.
 
The loudest part of my PC for sure.
I have managed to silence everything. To be honest I was aiming for silence PC, didn`t thought of this at the time :(.
I knew Sapphire had problems with they whining 79xx, well not only Sapphire but was hoping the vapor-x with black diamond chokes would sort this out.
Apparently not.
 
Sapphire and Asus have winning fans...
MSI or Gigabyte or even his when you are aiming for quiet pc.
My aim was silence as well and Iv reached it!
