I have Gigabyte 1660 Ti. This model: https://www.gigabyte.com/Graphics-Card/GV-N166TWF2OC-6GD#kf
And I also have everything set in msi afterburner like this: View: https://imgur.com/a/Sp9sWwu

Also, my case is this: http://www.deepcool.com/product/case/2014-09/9_989.shtml
And this is how it looks inside of my case: View: https://imgur.com/gallery/jUT97WN

I have 1 intake and 1 exhaust fan that are these: https://www.arctic.ac/eu_en/f12-pwm-pst.html
When I'm playing pubg or any other gpu heavy load game it reaches 68-75+ celsius and when it hits fan speed of 100% it sounds like this: https://soundcloud.com/arnas-liegus%2Ffan_speed_of_100
Can it be that my gpu reaches 75 celsius, because the outside temperature is over 31 degree celsius and in my room it's about 28+ celsius?

I mean... A closed case will always be hotter for all components than an open top or open side case. That's just a global rule of thumb. That being said, and looking at the information you provided, 75°c for the GPU is perfectly fine. The sound of the fans hitting 100% is the annoying bit, but you can't have both with your current setup up unless you improve airflow by either adding fans or making sure you have more natural fresh air intakes.

I wouldn't worry about outside temperatures, but humidity. A high amount of humidity makes moving heat a bit harder, so you'll need more airflow if you live in a place with high air humidity.

Cheers!

I tried stressing my gpu with MSI Kombustor and at 93% usage it reached 85-86 degrees celsius. Is that okay?

Since that is an unrealistic load (on most accounts), it should be fine under real games. I always use 85°c for GPUs is the yellow line and 95°c as the red line.

Cheers!
On games like PUBG, it uses almost even up to 99% of the GPU and my gpu temp limit is at 89 degrees celsius, so I set my fans at 100% when it reaches 86. Though, the highest temps I got while playing PUBG was 86 and when I played other games like The Forest without having msi afterburner which is heavy gpu game as well, my pc after a few minutes of playing just shut itself off, because of overheating I guess.
 
Ok, then it sounds like you do have a problem with ventilation inside your case.

I would suggest you use a "strategy" for cables and fans to align the air going from front/down to back/up. That fan at the back of the HSF looks suspect as well. Those types of fans should have a higher volume movement than the ones inside the case, so they can improve flow and not stop it. Sometimes, removing those can help a bit in favour of putting them somewhere else as intake.

As for the GPU's particular case, you could remove a secondary PCIe slot cover so there's a bit more fresh air to suck from?

I have noticed that this is only happening after I upgraded from gtx 950 to this 1660 ti. I never had to install msi afterburner with my old card and it never sounded like what I hear now. The strangest thing is that I use the same settings like with my old graphics card, but I have more problems now.

It is a more powerful card (in terms of consumption and performance), so that doesn't surprise me. That being said, the difference is small. Small enough to say it should not be a problem. I wonder if the cooling of your GPU is just worse than the cooling form the GTX950 you replaced... Also, the temperatures you gave are not that bad either.

What about your CPU temperatures?

Cheers!

I have hyper 212 evo on my cpu so it almost never reaches 70 degrees celsius. I had this model: https://www.gigabyte.com/Graphics-Card/GV-N950WF2OC-2GD-rev-10#kf.
My current graphics card is not overclocked and it reaches 80+ degrees celsius, so I would imagine what would happen if I overclocked it. Also, it's 20 degrees outside and my gpu never went above 71 degrees celsius now, so I guess I should play heavy gpu games only when it's not hot outside.

I compared the cooling solutions of both and they are more or less equal. To make sure it's not the GPU, can you try underclocking it? As in, make the Turbo speed lower than advertised; reference clocks even. This is just to make sure the problems you're facing are not due to the card having power or temperature issues.

As your CPU is also running cool, we'll have to start doing this little by little.

I lowered my gpu to this: View: https://imgur.com/a/NeMn9SY
and was stressing it out for 10 mins with 93% usage and got 81 degrees celsius. Also, I did another test lowering it to this: View: https://imgur.com/a/cxfFA0r
and stressing it out for 10 mins with 93% usage got 81/82 degrees celsius.
 
Looks like you need to set a custom fan curve for Video card and case fans.
A little cable management would help some.

Case fans are most of the time controlled by the motherboard, and are CPU temperature dependent. They run at slow speeds until the CPU gets hot.
Your cpu does not get very hot so case fans do not ramp up in speed.
My GTX 1070s will run 75 to 80 degrees without custom fan curves. With them they run 65-70 for EVGA SC and 67-72 for ASUS DUAL .

Power limit at 100% is fine; just like clocks at stock level. That's basically making the card work "in-spec", sort of speaking.

Have you experienced any crashes or something?

Cheers!
No, I haven't. I only experienced one pc shutdown when I was playing The Forest without msi afterburner.
 
If you are not looking for maximum FPS for first person shooters the simplest option is set Adaptive in Nvidia Control panel.
Nvidia Control panel
Manage 3d settings
Power management mode
Choose Adaptive.
This will try to limit frames/power consumotion to match your monitors refresh rate. why produce 200FPS if your monitor can only show 60-75-120 or 144.
It will vary slightly up or down to your monitors refresh rate by a few frames but you card is not producing frames you can not see any way. And produces less heat.

Try running with the case side off. if temps and/ OR fan speeds drop dramatically you need better Case Air Flow.

If no difference return the card.
Looks like you have a MSI board ,if so use their motherboard software to increase case fan speed .The front intake fan is restricted by the punched hole intake mount by 50% +/-.

Yup.

If you have zero issues and it runs stable, then it is related to the GPU. If it still freezes or crashes, then it's something else.

Cheers!
I was playing it on the maximum possible settings with this underclocking: View: https://imgur.com/a/TKM1AaI
and I reached over 130 fps and even higher with around 95-98% gpu usage, but the weird thing is, my gpu temps stayed at 66-67 degrees celsius while playing it for 30 mins.

I have set it in Power management mode on Prefer Maximum Perfermance, Maximum prerendered frames at 1, Threaded Optimization is on as well while everything else is on default. The heat stays the same unless I put my fan to blow air into it, then it drops 1 degree celsius.

And the important question: did it crash or have any visible issues to you?
