Hello, after searching for hours on internet, i couldn't find any reliable aftermarket air cooler, compatible water block or aio, even kraken g12 has compatibility issues with this board.
 
It's kinda sad this gpu doesn't have any way to get better temps with aftermarket stuff, im 30-35°, it's pretty hot here so my gpu is constantly on 80° when i'm gaming.
 
Could someone recommend me a mod, aio, or something that i'm missing to get better cooling? my case has great airflow, cpu is 55° at maximum with aftermarket air cooler, but i can't get the gpu to sit under the 80°, my gpu is a rtx 2060 Ko Ultra :(

Have you looked at universal waterblocks?  Those might work but that's if you're interested in a custom loop instead of a AIO.
 
Also, contact NZXT during business hours to verify if the G12 is compatible or not.

I would think the ekwb vga supremacy block would work on that.

I need to save up money but thanks for the advise.

That's what I was thinking. 
 
Most or some universal blocks will work on your standard GPU but I would make measurements or at least contact the company to verify.  

OP, if a universal block is expensive to you than a custom loop is out of the question and you're only left figuring out a way to figure if there's a AIO solution that exists or just air cooling.  The only ones that I'm aware of as most are is the G12 as a AIO hybrid bracket for the GPU.
 
With that said, give us a list of your PC components including the case, fans, etc. used as maybe we can figure out a way to decrease those temps. 

Here is my pcb imgur. com/gallery/JNNa2Bu it looks exactly the same as the one here youtu. be/VpEIEXxdBhQ?t=464 at 7:45 you can see the issue with the g12 then he just forced it but seems so sketchy and stressful for the pcb.

Then im only left with some mod like this youtu. be/h6hvsqUEtZ4?t=219 you can see he did a custom socket for an air cooler on minute 3:40-3:55.

I have like 12-13cm under my gpu (if i remove the heatsink and fans) so i was thinking on doing this mod imgur. com/gallery/M1fXsV2 but im afraid that air cooler is rated at something like 100tdp and my board is 160 or so. You can see my case, all air is straight front to rear, i tried the top fans as intake and exahust and they made no difference, so i just left there at the lowest rpm to prevent noise.

Also i was thinking about the 'arctic twin turbo ii' i need to check space.

You never want to run the case fans or any fan for that matter at low RPM for low noise when you feel you're having thermal issues.  I personally think 80c for a GPU is fine on air.  90c is another story but you can't have quiet air cooling and low thermals.  It doesn't work that way as you'll have to find a happy medium between the two.

Everytime i do a gpu stress test it goes to 82° but the top fans position (intake or exahust) never make a difference no matter at which rpm they are working:/, not sure what else i should try

My suggestion, in the future, is to save up for a more powerful card with better stock cooling. By the time you have this card in the temperature range you want, you will have spent as much as a 2070, and could have saved a little longer for the better 3 fan cooler.

Most lower tier cards won’t have water blocks because there is no point to paying so much on watercooling or finding a way to fit an AIO, when there are better options available.

Not everyone are experts on these topics, people like me just do a basic research on gpu capacities but not on thermals, it was my bad to think any gpu at this pricepoint is prepared for any type of city, cold or hot, now i know the cons of the "cheap" evga 2060 pricepoint, but thanks for the advise i should be more aware of this since now.

Arctic accelero will cool that baby flawlessly.

Arctic accelero will cool that baby flawlessly.

i was unsure about getting that but i saw someone getting it to work on this layout with a bit modding so yea ill try

im running a ryzen 5 3600 and evga rtx2060 ko ultra and i have a coolermaster 212 rgb black cooler on it in a nzxt 510 case and using msi afterburner and told im getting really good temps.link is me in modern warfare.
 

I have the same air cooler for my cpu on a corsair 220T but for some reason gpu was on the 80°'s, i undervolted to .930 and getting 1920mhz, im a bit confused on the "stock" mhz because evga website says it's 1755-1800 or so, but everytime i "reset" it via msi afterburner it goes to 1920mhz at peak, anyways with this undervolt i finally hit 70-72° when playing cod, i think it's ok now

This is caused by GPU Boost 4.0, an overclock built directly into the card. The stock numbers are minimums that EVGA guarantees, but the true numbers that you get are due to GPU Boost 4.0 seeing that the card has more capability to go to higher frequency while remaining within the safe ranges.

well i have a msi b450 tomahawk mobo the other day i was in modern warfare and i use msi afterburner to monitor cpu and gpu temps and i was running 78c to 82c temps with my evga rtx 2060 ko ultra and was freaking out like **** is going on. i just built this rig 2 weeks ago and been running 59c to 64c. well the mobo has balance mode and performance mode and i forgot i put it in performance mode, when i changed back temps returned to 59c to 64c.
 
dont know if your mobo has these options so check to be sure its not something as simple as that. im not a tech guy im a noob when it comes to troubleshooting and glad it wasnt somthing serious.

Even with those temps you were fine.  It could be a case fan profile so in performance mode, the fans are spinning faster to cool the PC vs balanced mode which probably runs slower where things will cook up more.
