I bought my Intel 12th-gen i9 in 2022, and lately my system has been black-screening more often when launching relatively light workloads, such as a modded Minecraft pack. I sometimes see a watchdog-related error, and the crashes seem to happen when temperatures rise, so I suspect overheating or instability. I have already tried undervolting, replacing the thermal paste several times, and upgrading to a newer 360 mm AIO with a better mounting system, but none of that made a noticeable difference. The CPU is paired with DDR5 memory and an RTX 5080. Should I keep troubleshooting the current platform, or replace it? I have heard concerns about 13th- and 14th-generation Intel degradation, even after the BIOS and microcode updates, so I am also considering moving to AM5.

Since you already have a 125 W power limit, see whether the crashes stop when the processor is running at conservative stock settings. Also try temporarily disabling XMP, updating the motherboard BIOS, and checking event logs for WHEA hardware errors. If the system becomes stable with XMP off or lower memory speeds, the problem may be memory or the motherboard rather than the CPU. Replacing the cooler again probably will not help unless temperatures are actually reaching the thermal limit.
If troubleshooting confirms that the platform is faulty and you want a meaningful long-term change, I would move to AM5 rather than buying another 13th- or 14th-gen chip. A Ryzen 7 7800X3D or 9800X3D with a suitable B650 or B850 board would work well for heavily modded Minecraft and gaming, and your existing DDR5 and RTX 5080 could carry over. Just remember that changing platforms means replacing the motherboard and possibly dealing with Windows reactivation.
A 14th-gen replacement is not automatically doomed, especially with a current BIOS and Intel's recommended power settings, but it is a questionable upgrade from a healthy 12th-gen i9. If your current processor passes testing, I would keep it and wait for a larger performance jump. If it fails and you need a replacement immediately, compare the warranty and price carefully rather than upgrading solely because the temperatures look high.
I would not assume the CPU is dying yet. 12th-gen chips are not generally associated with the degradation problem that affected some later generations. Before replacing anything, test the system at BIOS defaults, check whether XMP is stable, confirm the memory is in the recommended two slots, and look for the exact watchdog code. Run a memory test and separate CPU, GPU, and storage stress tests so you can identify which component actually causes the black screen.
The RAM is in the correct slots, only two slots are populated, and XMP is enabled. I reset most BIOS settings after struggling to stabilize it. PL1 and PL2 are currently limited to 125 W, but I have not changed much else because I am not very comfortable with advanced BIOS settings.
