I'm experiencing some serious thermal issues with my Intel i9 13900KS while playing Battlefield 6. My CPU temperatures spike between 92 and even hit 108°C at times, despite having a Corsair 360mm H150 AIO cooler. I've tried undervolting the CPU and cranking up the fan speeds, but nothing seems to help. I'm not very tech-savvy, so I'm looking for any advice or suggestions on how to tackle this heating problem.

Wow, that's a hot CPU! Disabling turbo boost might help reduce the heat, and limiting the max frequency could be a safer bet than undervolting. But make sure no one left the protective plastic on the AIO before installation—that could definitely cause overheating. Check for good thermal paste application and see if the fans are blowing hot air; if not, there might be a larger cooling issue.
Yikes, those temps are intense! Make sure you're checking your CPU cooler properly. If it's air cooling, just visually inspect it to see if the fan is spinning. If it is, it might not be making good contact with the CPU. Pull it off, apply new thermal paste, and remount it carefully to ensure even pressure. If you're using AIO, check your BIOS for fan speeds to confirm the CPU fan is running. Also, inspect the power connector from the cooler to the motherboard—make sure it's plugged in tight.
Don't forget to check your BIOS settings and disable "IA CEP"; that might prevent some thermal overload issues.
It sounds like your AIO pump might be malfunctioning. Try placing your hands on the pipes near the pump—if you don't feel any vibration, the pump could be dead, and you might need to replace the entire AIO unit.
