My GPU temps climbs higher and higher when gaming until it reaches about 80 degrees Celsius and crashes. I'm starting to wonder if it's because of airflow. I live in Sweden with about 22-23 degrees in my room. I have a Ryzen 2700x together with a Corsair Hydro H115i PRO RGB AIO in front as exhaust and then a 2070 non super. My fan setup is as followed: top and back fan are both 120mm as intake, then the rad fans are both 140mm as exhaust as previously said. All of this is in a NZXT H500i on my desk. Should I re-configure anything or is it even airflow that is my problem?

That case is so closed off, not only doesn't it let air in, it also keeps the dust out as well.
Wow, that's the polar opposite of contemporary case engineering! No, I'm not being smug either. I've come to HATE my case. Take my advice guys, please. Stay away from MountainMods cases. The company is dying and they want to take your cheddar with them.
I don't know UsandThem, I'd rather brave the dust monster than fry-out my parts.

I think you misunderstood what I said, as I agree 100%. But there are also great cases that offer good airflow and dust reduction (like my Be Quiet Dark Base 900 and Fractal Design R5 cases).I don't know UsandThem, I'd rather brave the dust monster than fry-out my parts.
I was saying the OPs case not only blocks airflow, it blocks everything. I was (attempting) to interject some humor into the thread.

I don't think that would block much air. Just turn off that fan, and plop a magazine/book on top of the vent area.
Just curious, did you get around to checking to see if the fans are spinning?
I notice your case has a usb controlled pwm controller. If your using the controller, I would check the software for it to make sure it is ramping up the fan speeds as your case heats up or just move all the fans to your motherboard's headers. That doesn't fix case design, but considering your dumping the radiator heat into the case it isn't helping anything. You could try reversing all the fans to blow back to front so the heat exhaust's out of the case, I'm not sure it will give you a big benefit.
For the sake of testing, how are the temperatures when the side panel is removed? Do you feel hot air coming from the exhaust fans? Do the sides of the case get warm after the computer has been under load awhile? Do the GPU fans ramp up to max rpm when the GPU heats up?

I am pretty sure that the fans are plugged into the motherboard, but I do remember the mobo having some places where it said pwm on them. I have also checked if I can feel any hot air coming from the rear fan for example and can't weirdly enough feel anything abnormal. The gpu fans are weird, they do ramp up but not alot, and when I tried making my own fan-curve it didn't help anything..
If your using afterburner or dragon, reset to default and see what happens. You could then try just setting the GPU fan to run maxed out all the time.
I think someone else suggested, you could pull the heatsink from the gpu for a cleaning, though your case looks clean, so I don't think you have any dust buildup, but it shouldn't hurt to check.
I would run it without the side panel (glass panel) for a day or two first and see if it is just choked air flow.

I've always had afterburner on default, so it can't be that. I will definitely try setting the gpu fans to max a few gaming sessions though to see what happens. One thing I observed tho while playing cyberpunk lately was this, I usually play in 1440p with ultra settings with a steady 60fps using DLSS but having the problem of overheating, but this time when I played, it had changed back to 4k without me knowing while at the same time being at ultra settings and getting 30-40fps max. The weird thing is that, when I ran in 4k ultra settings with 30-40fps I got pretty good temps with maybe an average of 70c, but when I play in 1440p with higher fps it's suddenly unstable. It's almost as if my overheating problem is fps based where the lower the fps is the better my temps are... Shouldn't it be the other way around that lower resolution with higher fps is a sign that the gpu handles it better?
CPU stay at about 50 all the time, but GPU temp limit are at 81C according to afterburner. If I turn it to max I will just delay the inevitable

Have you tried anything to improve thermals yet?
No, I'm waiting for my uncle to come over and help me. I'm handicapped so I can't lift my arms and stuff, so I need somebody who knows what they are doing aka not my mom or dad

You mentioned earlier that making changes in afterburner didn't seem to help. Did you click the checkmark after you made the changes? My 1660 super and 1060 6gb ran around 33% fan speed under use. GPU temps were between 65 and 70 C. I'd expect the fan speed to keep going up if temps increased.CPU stay at about 50 all the time, but GPU temp limit are at 81C according to afterburner.

If you press the restart circle it won't let you press the checkmark, if you change something it will however. But yes, when I made my own fan-curve and whatever I pressed the checkmark.

Sorry i am late to this...
Okey your issues:
1. The radiator should NEVER draw air from inside the case unless its an open case as the higher ambient air will increase water temp, and thats not what you want.
2. In the case, have the Fans pull air from the radiator like you have in your picture only in a 180 degree direction.
(case) (rad) (fan in pull)
This will supply some wash air to your GPU.
If your fans are on PWM, then you need to tweak your fan curve.
Have the rear and top fan push air Out of the case.
Make sure your PSU has the fan sitting up top, so its also pulling air from the case and throwing it out the rear.
tldr;
Remount radiator so the fans are on the other side of the rad, having the fans pull air from the outside to the radiator inside the case.
Tweak fan curve so they are not running at 900RPM's all the time.
Rear and top fan should be pushing air outside the case.
PSU fan should also be pulling air from the top chamber, and throwing it out the rear.

What do you mean with "180 degree direction"? Also, shouldn't it be better to have the PSU fan directed downwards as the case has a specialized cutout for the PSU so it doesn't push hot air into the case?

It's a non-issue to have radiators working as exhaust, and it's typical of top mounted radiators, and they still work fine. Plus his issue isn't CPU cooling, which is working fine. The best solution would be if this crappy case allowed him to top mount the radiator as exhaust to have negative pressure. But this crappy case doesn't allow that either.
His issue is GPU cooling. He has a crappy case that is designed for negative pressure, to pull in cool air through Card slot covers to cool the GPU. It actually does a decent job of GPU cooling in that configuration.
You can't count on Modern PSU to provide case exhaust as they tend to move negligible air, only enough for their own cooling. (Mine doesn't even turn on until it's pulling 300+ watts).
Several tests here with PSU up/down in different cases, and differrent GPUs (open air and blower)
TLDW: PSU orientation has Absolutely ZERO impact on GPU/CPU Temps. It only impacts PSU temps.
So we are back to the original problem. Crappy case, that can really only cool GPU decently with negative pressure, so it is back to creating that negative pressure.
So counter-intuitive to normal case airflow, run the front Radiator fans, as exhaust (and max out the fan curve).
Don't run any Intake fans at all. You want negative pressure, to pull air in through the card slots to cool the GPU on it's way out the radiator.
