So I bought GTX 1070 EVGA Founders Edition card on caseking.de last week.
I finally received dmy GPU, and noticed that it has annoying coil whine while gaming. It has nothing to do with FPS, but probbably with clock speed or power draw.
In some games I get 60fps at power draw below 30%, and there is no coil whine.
But in another game I get 60fps at 60% power draw and higher clock, so it's causing coild whine.
 
I did put on waterblock from EKWB, and it's cooling just fine, but that coil whine is killing me.
Does EVGA accept RMA for cards with coil whine? Any way to fix that by myself?
Do I have any rights to return this GPU to caseking, and get full refund? Keep in mind that I did put on waterblock, and I'm not sure if that void warranty or not. There is some sticker on backplate saying that if it's removed it will void warranty. But that sticker is not covering any screw, so it's still untouched.
 
Last time I had R9 390, it didn't have any coil whine even at 200fps and 80% power draw, so I'm not sure why this card has one.
I just don't wanna have GPU with coil whine.
Building water cooled PC, just because I'm trying to get it silent, and then I get card with coil whine that is louder than all fans and pump in my case ... it just makes me sad.
 

What I'll ask you to do is to contact EVGA EU for assistance:

They do not work on the weekends so you need to wait until this week.

 http://www.overclock.net/t/1094728/possible-fix-for-coil-whine Contains information on coil whine. It suggests that tweeking the voltage slightly may help.

I did also find this, but I tried increasing voltage ... nothing changed.
Someone said that he did 12 hours burnt in test or something, and it made coil whine dissapear. No idea how to do that.

Just run a benchmark test continuously that causes the whine. Maybe Heaven? its free. just twiddle the settings until you get the problem, then walk away and let it run.  https://unigine.com/products/benchmarks/heaven/

If you can't get the coil whine to dissipate, it is in the EVGA warranty information that you simply have to return to card to it's original state and not to have done any physical damage to the card to RMA it.
 

Thanks for all the answers.
Problem with coil whine will appear as soon as I start heaven or valley benchmark, so I will just run that over night and hope it will fix itself.
 
I already got respond from caseking ... they won't accept my card because I voided warranty.
It's a bit confusing why do they decline warranty, if EVGA allows us to remove stock coolers. That's just dumb.
 
Anyway, if that coil whine won't go away, I will contact EVGA and hope they will accept my RMA :) 

To update this: someone provided me this answer from EVGA, when he had problem with 780 ti coil whine.

We recommend testing your video card with another power supply, as often the power supply is a cause of noise issues. If the power from the PSU fluctuates, it can cause the coils to vibrate resulting in coil whine. You can check if the PSU is providing consistent power to your GPU. Go into your BIOS and look for the +12v reading. A healthy reading is between 11.4v - 12.6v. If you observe consistent fluctuations of more than .05 volts, the PSU is faulty and might be causing the errors.

 
I checked in BIOS and voltage was at 12.00V.
I was also able to monitor that voltage with MSI command center. When PC is at idle and nothing is realy going on, voltage seems to be at 12,000V, but sometimes jumps to 12,096V.
And when I run stress test or play games, that nukber will go to 11,904V. That's still between 11,4-12,6V and should be fine.
But what do they mean with that .05V consistent fluctuations? I'm not native english speaker so I don't realy understand this.
I tried to use differend 8pin connector, differend cable, differend expender, I even used that splitter, so I had pluged 2x 6pin to 1x 8pin cable that came with GPU. Tried every single combination of those cables, and voltage remains the same. 12,000 or 12,096V at idle, and 11,904 when gaming.
Should that be the problem? I mean it still in safe range for that voltage, and I was using it on previous GPU ... never had problems. But I don't know what voltages I had before because I never looked into this.
Also my PSU is pretty decent, so it should deliver power as it have to do.

If you monitor the voltage on the 12v line, if you see constant changes of .05v or more. Under constant load conditions, the 12v line should be relatively stable. Check your readings when running the benchmark and see if you spot any trouble signs.

I was monitoring it, and it's stable at 11,904V when benchmark is running.
