I recently bought a supercharged PC with an i9 9900k and it has the H100x AIO cooling kit. I haven't had any issues where things break or games crash when using this setup. After one game got stuck and just crashed for nothing, I started doing hard tests on my computer to check if everything works properly.

I used Aida64 to run a stability test for 30 minutes, and the temperatures stayed mostly around 82-85 degrees with some cores going up to 90-92 degrees. I also ran the CPU-Z stress test which usually stays around 82-85 even after more pressure. Does this look okay?

Those temps look pretty okay for that cooler. But personally, I think an H100X isn't strong enough for the 9900k and it gets beaten by better air coolers. You should probably get a 280 or 360 AIO instead.

Those temperatures are just right for that cooler. Personally, I think an H100X isn't strong enough for the 9900K and gets beaten up by better air coolers. It should get a 280 or 360 AIO instead.
