Question High temperatures on my 5900x

[afranklin98]

I am idling at 70c and hitting 85-92c+ when on marvel rivals... I just recently found this issue as I have never checked my temps in a while. I recently fully cleaned my radiator fans and my whole pc, so that's not an issue, as well as new thermal paste so that's probably not the issue either... is my AiO just gone and I need to buy a new cooler I don't understand. (Yes I know it is a prebuilt don't roast me I got it for free from a friend, but I changed the CPU to a 5900x)
Cooling: 240aio deepcool castle 240ex (from xidax so prebuilt), then 3 back right fans.

pump fan speed in bios
general temps/fan speeds
specs (except for I have a 5900x now)
pc

For your AIO, is one tube getting hot while the other tube is cold? If so, then the pump might've cavitated. Is the radiator dumping any heat? If yes then your AIO is working as it should. You state upgrading the processor, did you flash the BIOS to the latest version before swapping it with the Ryzen 9 5900x? What thermal paste did you use after swapping the processor?

Looking at your case, are the side fans oriented with them set to intake air into the case? Aquarium style cases work best with the airflow from the bottom to the top, like a chimney.

Please stick to one thread unless you want spaghetti brains.

The 5900x was october 2021, I updated the bios, then... I haven't updated it since, should that be something I try? Also I can't really tell if the tubes hot but the overall ambient temperature of the pc heats up the tubes so it feels warm in the first place. I've always used the same thermal paste, arctic mx-5... You talk about the pump cavitating, how exactly would I fix that, or would I just have to get a new cooler... I'm pretty sure at this point that my cooler is just messed up. As far as I know all 3 on the back are intake, as the blades are curving away.

I'm sorry about making two threads, I just wanted maximum visibility, appreciate you though.
