Question High GPU Temperature and potential overheating?

[ReeDoK]

Hi everyone! First of all, I'll write my whole PC specs before anything:
CPU: Intel Core i3-12100
CPU Cooler: Arctic Freezer i35 A-RGB
RAM: 16GB Kingston Fury DDR4
Motherboard: MSI PRO H610M-G (latest firmware update)
GPU: XFX SPEEDSTER SWFT210 RADEON RX 6650 XT (yeah long name, but better to be precise, it's the model with two fans)
PSU: MSI MAG A750GL PCIE5 80 Plus Gold 750W
Case: Segotep X1 Black
SSD: Kingston NV2 1TB
OS: Windows 10 LTSC 21H2 (maybe it's important to note this too)

Ok, so today I was playing Ghost Of Tsushima in 1080p native, High settings and I was getting around 70-90 FPS, sometimes 100 depending on the area. During combat, my PC just shutdown, twice. The screen went black for 2 seconds and it just shut down.
I'm suspecting the GPU is overheating, it's temperature is around 87 celsius and the hotspot is reaching 110 degrees, which I believe is the maximum temperature for this card. It does not happen in other games (not that I am aware of), but the hotspot is always very high and the fan sits at 66% (according to MSI Afterburner). I could try to increase fan speed, but now I'm afraid to launch any demanding game. Both the GPU and PSU are still in warranty. You may be asking why I want such high framerates in single-player games? Well, I have a 280Hz display so having that many frames makes the games a lot more smoother.
So what problem could be here? Should I try undervolting and increasing fan speed? Is it even normal for this GPU to be this hot? I suppose the case is not that great either.

My reading says that the case has room for two 120mm front intakes and a 120mm exhaust.
Normally that is sufficient to provide sufficient cooling airflow to the cpu and the gpu. See that the front intakes are running sufficiently fast. Check the motherboard bios fan profile settings.
You could replace the front intakes with higher rpm 120mm front intakes.
Or, as you suggested, the case is not that great and could be replaced.

That pc case is not suitable for gaming grade components.
Try running your game with side panel removed and observe cpu and gpu temperatures.

Ultimately you should replace your pc case with high airflow model (mesh front) and
2-3 intake fans in front, 1 exhaust fan in back.

Your fans should be wide open at those temps not 66%.
Set a custom fan curve in MSI afterburner just 2 points will do 50C=20% 80C=100% then check the box to make it active when you boot.

That should do it.

Yes, I have mounted one fan in the back and two in the front, but I'm afraid these two front fans are not doing anything because the case has solid panel in the front, so I'm not sure if it matters that much

This kinda works (no crash so far) but the card becomes almost too loud to enjoy my games, especially when using speakers.

I did try to remove the side panel and I'm starting to believe the case is indeed the main problem here. Hotspot temperature dropped from 107-110 to around 103 and the fans don't spin as fast as before. With the side panel mounted, I can almost smell some hot air that is probably accumulating inside.

Solid front panel in front of fans?? Quch!
I think there are some side vents but really, a decent case would be a good change.
Where do you shop?
Do you have a budget?

What are the temps running 100%?
You got to run the fans fast enough to cool the card.
