Hey!
 
I've got a 1070 SC and I will occasionally hear coil whine when it's under stress (for example, FIFA 16 opening intro with unlimited FPS). However, it's truly not that loud (I personally would never complain about it).
 
If you are sensitive to noise and need everything to be at completely quiet then you'll have some issues when the card is under stress. 
If you're like me and have headphones / music / sound playing almost constantly, it won't bother you. 
 
I highly recommend these cards; they're really great! The coil whine should definitely not be a reason to not buy the card.

Hello Adger and welcome to the Forums!
 
Any high powered electronics give off coil whine but it is typically outside of the audible range. Sometimes the whine is able to be heard and it can be quite annoying. This is regardless of brand or model (although with cards that operate at a higher frequency require more power which can increase the odds of coil whine). It also depends on the other components involved such as the power supply. If you find your card does have coil whine, I recommend the following:
 

1. Test the product another system or test the current system with another power supply unit. This can be the cause of the sound which can manifest itself through the graphics card or power supply.
 
2. If you are using a UPS (battery backup) or power strip try plugging directly into the wall outlet to see if this may resolve the issue.
 
You should be able to know if your card will experience this within the 14 day window of testing. Run some benchmarks, play some games. Test thoroughly to make sure you are satisfied. If you miss the return window just contact us so we can look into options to assist you further.

Cheers for the reply Joseph. I now know why EVGA,s support is highly recommended,I'd have a problem testing it with another psu.
But like you say I've got 14 days to try. Thanks again pal

my gtx 1070sc only seems to coil whine really badly when playing doom on vulkan api during the initial loading of the game then stops strange it doesn't do it when playing on opengl, haven't really noticed it whining while playing anything else  

No coil whine with a standard 1070 ACX 3.0 overclocked or not. I had some before with a GTX 970. As said before it's just a matter of luck with the card and it's not linked with the brand or the model. Maybe cards more powered like the FTW are more exposed? As Pascal seems to overclock pretty easily I would go with a standard card like mine and overclock it yourself.

No coil whine on either of my 1080 FTW's

my 1070sc only has coil whine at high fps
gets rather loud when overclocked for benchmarking
but at stock clocks with 60fps cap i dont hear it
may be a problem if i had a 144hz monitor

I replaced my gtx 1070 ftw with new one and still have coil whine on this one too. I think coil whine can be eliminated with 850+ power supplies.

But from my notice from different forums and reddit posts evga psu under 850w + evga 1070 = coil whine. This what i noticed from specs of people experiencing coil whine. I have evga 750 p2 evga psu still got coil whine on my second 1070 ftw too.

Thanks guys for all your advice and information.
I only have a corsair tx650 psu,I've actually tried a friends 1080 in it (different brand than EVGA) and it was silent.
I've been lucky I've used 3 different cards with this psu and every single one has been perfect.
Does anybody have a lower psu like mine and NOT have any coil whine issues?
I'm not going to replace my psu it's been perfect. I really really wanna go with this EVGA FTW 1070 card. I was actually going to pick 1 up today or definitely tomorrow
But if I'm been honest ..I've noticed more postings regarding coil whine issues on the EVGA cards than any others on different forums.
Thanks all

Edit:@Darkstar child,just read your original post very interesting regarding your testing with different psu,s.
Are you still within RMA range? Why not return your card mate.
I think I'm going to hold fire for a day or 2 I've no qualms RMA ing a card if it's not what I'm expecting.
I'd just rather avoid RMA ing if possible

Thanks for your input pr00f, it does seem that there's a fair few posts on different forums, where people are having issues on the EVGA cards. There's also a lot of people who are having coil whine issues on the Msi cards aswell though.

I don't know if it's the luck of the draw with GPUS or not but in my opinion if I'm paying upwards of £430 for a GPU I expect it to be nigh on perfect.

But you have to convince the tech support guy or the guy testing your gpu for rma. He may not count coil whine as defect in gpu. Prior discussion with retailers or sale rep is the best way to solve any problems or issues you might face.

Hi Adger, please post back on whether your new 1070 FTW has coil whine or not.   I'm also interested in buying a 1070 FTW, but I am waiting a couple/few more weeks until the price drops a little more.

I get terrible coil whine with my FTW at stock and overclocked :( Its a shame cuz its a decent overclocker ...hitting 2135mhz on default BIOS and maxed out power/temp limits...stable 2101mhz on Heaven loop. 
 
Tonight ill try the 2nd bios with 130% limit and a move aggressive frequency/voltage curve in Afterburner 3beta..hopefully get 2150mhz stable
 
But the whine is pretty bad :( Not sure if i should RMA it 

I've been keeping a close eye on this forum for just over a day now and..
I must say I'm very impressed with the EVGA reps that are on here giving quick and sound advice
Are they always this good?
Anyway I'm 100% going to purchase a FTW 1070 card within the next few days. Just because I've seen how good EVGA are. And fingers crossed I get a great card (haven't had much luck lately,just had to purchase a new MB)
I have 2 6+2 pin connectors on my PSU,I'm right in saying this is good enough to run this card?
Thanks all
