I've been using the Intel i9-13900k for about two and a half years, and I'm noticing some concerning behavior. Despite having updated the BIOS, undervolted it by -0.100, and underclocked, the CPU temperatures are still high. While idle temperatures range from 40-45°C and light tasks like browsing come in at 55-60°C, it gets much hotter when gaming—like around 75-80°C for League of Legends and 80-85°C for CS 2. However, during more demanding games like Diablo 4 or Battlefield 6, the temps shoot up to 95-100°C. Stress testing the CPU causes immediate thermal throttling. My cooling system is the H150i Elite AIO, with fans and pump set to extreme, keeping the cooler at about 35-45°C.
Additionally, I've faced some BSODs lately, particularly with Driver Exception errors, which might indicate a CPU issue, especially since I've also noticed the System Interrupts process spiking in CPU usage recently. I managed to run a DISM restore which fixed some corrupt files, but the CPU temperature issues persist. The PC has been stable without BSODs for the last few days, but I'm wondering if these problems point to a failing CPU or if there might be something else going on. Should I consider replacing my CPU?

To better analyze the BSOD, you'll want to check for dump files in C:WindowsMinidump. If you find any, zip them and upload them to a file-sharing site. We need multiple files for a clear picture of what's happening. If you don't have any, follow the guide to set up your system to create small memory dumps for future crashes.
You might want to try manually setting your CPU to 5.6GHz on all cores and disable hyperthreading. Reducing the number of active cores to just 8 could also stabilize things. Don't forget to use a fixed voltage starting from around 1.28V and adjust from there if needed!
BSODs like Stop 124 can indicate CPU degradation. If your prior overclock settings suddenly aren't stable and you find yourself needing to increase voltage, your CPU could be failing. Definitely monitor your settings closely!
It doesn't sound like your CPU is dying. The i9-13900k is known to reach high temps and throttle, even with decent cooling, unless you set power limits. Instant throttling in stress tests is quite common for Raptor Lake chips. As for the BSODs, they're likely due to unstable power or RAM issues rather than a failing CPU. Try limiting your PL1/PL2 power settings and check your RAM stability before considering a CPU replacement!
Have you checked if your AIO cooler might be malfunctioning? If the liquid is evaporating or if there's any gunk forming inside, that could restrict its cooling efficiency. Ensure the pump is running consistently at full speed. If not, you might need to consider a warranty claim or RMA for the cooler before thinking about replacing the CPU.
