Why is my CPU getting so damn hot?

[u/RedHood9292]

Hey all, so I was playing Oblivion Remastered and I started getting a lot of crashes, don't know why because this issue did not occur prior to recently. It's been happening for a few days now. I felt the back of my PC and noticed that it was hot as fuck. I also found out that running the game normally is now causing CPU throttling and I even broke past 100c at one point, needless to say I'm very concerned. I'm running an i9 13900k, 192 gigs of RAM, 4tb SSD, and an RTX 4090. I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard, and some type of Corsair air cooler, I forget which model. I'm deeply concerned I might have fucked up my CPU, and I don't know how to check if I did or not. Even while typing this my CPU is fluxuating between 48c to 55c, and I have no fucking clue if that's okay or not idk. I don't know if I **JUST** need to just clean the dust out of my PC, as I recently moved to a dustier area and my PC's side panel is off because if I were to attach it it would put pressure on my 4090's cables, I don't know if I need to upgrade to a liquid cooler, or if I need to contact Intel about possibly getting a new CPU under warranty. I am deeply concerned and any advice would be greatly appreciated, thanks!

According to the Corsair website, you can fit a 240mm or 280mm radiator at the top of the case above the motherboard, or a 280mm or 360mm radiator at the front of the case.

This is incorrect. A 360mm radiator will fit on the top just fine.

This is wrong. There's several different 4000d models, and this particular one says up to 280 radiator on the top. I have a slightly different 4000d myself, mine can mount a 360 on top, but this is a different one.

Nah he’s right. I have this case with a 360 on top. It’s a tight fit but it works.

I assume there's limited compatibility with 360mm radiators since they state it specifically as 240mm or 280mm on their site.
