POE2 Overheats my CPU to 100c and PC force shutdown

Look into undervolting your CPU. I know with AMD chips its super easy to do. I've got mine (7800X3d) so it won't go above 70c and its great. Hardly any performance loss (5-8%).

I also undervolted my 4090. Again, totally worth it. That thing consumes a ton of power for no reason by default.

If I were to stress my 5900X, it would probably reach around 100 degrees, but today you wouldn't want software doing whatever it wants with your hardware, that's why you have programs like QuickCPU, for example.

The is a common issue with recent motherboard manufacturers where they like to just shove voltage though the CPU. This has been going on for almost a decade at this point.

Literally everyone should be setting manual voltage and clocks on their CPUs these days. If you don't know this is a very common issue with modern CPUs. Now you do.

I have a 13600k OC to 5.4Ghz set to 1.3v. I have never seen it go over 75C on Air even after multiple Cinnebench runs. Modern CPUs have censors in the cores so you will see an idle spike go from 34c to 65c for a microsecond. That's just how they are.

A consistent 100c Socket or core temp is a critical cooling / voltage issue.
You can to take care of it yourself because MB manufacturers don't care.

This is because frame limit is DISABLED by default

Instead of ENABLED by default

Also on something like this. Always use something like Riva Tuner to set your Frame cap globally so no program can lets your GPU to crank higher than you've set it.

When you manually set Voltage, Multipliers, frame caps and similar. Programs have nearly no chance of causing damage to your PC. They especially can't make it work harder than it needs to.
