I recently built a new PC with an AMD Ryzen 7 9800X3D and used a Corsair H60x RGB Elite AIO cooler. After flashing the BIOS and getting the system up and running, I noticed that MSI Afterburner showed normal temperatures initially. However, upon rebooting into the BIOS, I received a temperature warning—despite the BIOS displaying a reasonable 40°C. When I checked Afterburner again, it bizarrely showed temperatures exceeding 17000°F! I haven't powered the computer back on since. Is my AIO cooler not adequate for this CPU, even when it's idle? I made sure to apply thermal paste properly, so I don't think that's the issue.

Honestly, a 120mm AIO cooler is pretty weak for a CPU like the 9800X3D. They're generally okay for lower-tier CPUs, but for this one, you'd probably want something more robust. It's surprising you saw temperatures that high at idle, though! Might be worth checking if your cooler is seated properly and if the pump is actually working. That 17000°F reading is definitely a sensor glitch!
Make sure you're using enough thermal paste and that you took off any plastic film that might be between the cooler and CPU. You mentioned it's a carryover from your last build, so double-check that everything is applied correctly!
I did apply thermal paste, so I think that part's all good! Thanks for the tip, though!
Definitely check if the pump is working—if the cooler isn't seated properly that could cause some real issues. But honestly, I think what you're seeing is more likely a misreading from the sensors rather than an actual overheating. Still, it’s best to get that sorted out before you boot up again.
Yeah, I'm planning to switch to a 240mm cooler. I think that should help, fingers crossed!
