After replying to here: forums.evga.com/Kind-of-a-clunk-noise-when-980tis-fans-start-around-the-35-area980ti-SC-m2441737.aspx
 
I got to test the issue further, downloaded PrecisionX, tried RPM ranges, anything above 1200 rpm, the GPU starts making clicking/rattling noises, increasing the speed to 2000 rpm really amplifies it, at 100%, the rattling is probably still there but more homogenous and undistinguishable
 
My card coil whines, my case fans are loud, yet this rattling is something else, the sound + worry gives me a headache, I can't use the system
 
I got the card from Amazon US, I'm in Turkey, the card has 79.6% ASIC, so I would really like to find a delay-less solution to the issue
(The card is almost 4 months old now)
 
Thanks in Advance

You don't have much choice... 
If you locate problem try to fix as other people or send card to RMA. 
I can tell you that very small number of people report that problem with GTX980Ti ACX 2.0...
If fan produce noise you can't do nothing. I can tell you my recommendation and I don't know what you think...
If card work normal, stable I would remove that ACX cooler and order Hybrid...
He will drop temps for more than 20C and all noise you hear will gone.
If you send card to RMA and people do that for similar problems you will pay shipping maybe almost as half of Hybrid cooler and plus days without graphic card... Now only stay problem of compatibility your card with Hybrid cooler... For that you need to ask EVGA.

Thanks for the suggestions
 
It's 100% the right fan making the noise, I can set the temperature target to 76C, lock the rpm to 900, the sound is gone, yet whenever the right fan reaches 1200+, the tickling appears, when I slow down the right fan gently, the sound immediately disappears, so it's something with the fan, and nothing else :(
 
The noise description: Accurately, it's like there is a piece of stone in the right fan, it's like the stone is moving inside the fan, making cracking noises
 
Q1) It is possible to receive a single fan and replace it myself instead?
Q2) Is the fans separately connected, maybe I could disconnect the right fan and leave only the left fan, or find a circuit to lock the right fan to 900rpm, as it is, I see a possible fan connection on the right, might be a led connection too, I'm not sure
Q3) What is the max safe temperature to run this card, when I set to power target to 94% and lock the rpm to 900, the temps near 90C, doesn't seem to work out well
 
As it is, I'm using the card practically as a GTX970 with the underclocking I have to do, to keep temps and fan rpm low, even if I set the priority to 82C, the card is at 600mhz under full load, considering with fans the capacity is 1400mhz, 600mhz is sad :(
 
+ EVGA's reply is a generic coil whine reply, but if you read anything I wrote, you can see it's actually a defective fan

I think you can find on Aliexpress some ACX coolers, fans, shrouds but I think that's most for previous generation, for GTX700 series.
New fans are with different blades than ex ACX Cooler. And usually even if you find they are very expensive. 
If you want something really good than Accelero Xtreme III or IV or maybe some of Accelero Hybrid.

Me too, I would try to keep card even if I need to buy new cooler.
But here with FTW situation is much worse than with Classified > EKWB waterblock, reference > Hybrid, EVGA Hydro Copper or EKWB waterblock, ACX 2.0 > EVGA Hydro Copper or EKWB waterblock. FTW no such options, nothing, only fabric cooler.
It would be much easier if reference turbine stop and you order Hybrid cooler.
Accelero Xtreme III could resolve temp problem nicely and it's not loud cooler.
