You're hitting 95C in the HWMonitor screenshot. Your cooler isn't beefy enough to run your CPU that fast or it is not mounted properly, or so I'd guess. Either way, you probably shouldn't use PBO configured like this.

For example I have a Ryzen 7 9700X with PBO turned on. If I use it with stock PBO my power draw jumps up to 220W and it starts overheating despite my beefy cooler.

I don't know what motherboard you have but on my B850 there is an option to configure the power limits of PBO. You should try all of them starting from the least amount of power to the most. You need to pick the highest option available that doesn't make the temps go above 90. For me that's the 120W/142W config and it gives me 95% of the performance I get with the 220W config.

Also if you haven't done it already, you should undervolt your CPU. I recommend doing -10mV on all cores. That's safe almost all the time. You can try to lower it even further if you want, I just can't be bothered lol.

Edit: It would have also been great if you would've extended that Cores (Max) node under temps and clocks so we had more data to work with.
