i9-13900k Intel Turbo Boost causing massive, uncontrollable temperature spikes.

[Merkava]

Hi, Thank you so much in advance for any and all possible suggestions/help/resolutions!

I have an i9-13900k that is cooled by a Arctic Freezer II 360mm as well as multiple intake/exhaust fans on the case. I used the best recommended aftermarket LGA socket holder for the CPU as I was told this would reduce temps, and I ensured mounting was done properly. I installed the MSI BIOS update last week per the direction of Intel as this was meant to resolve many of the temperature issues with these chips and the motherboard manufacturers. Sadly, I still am unable to get good scores on Cinebench with good temperature. The only thing I have managed is to control the temperature, but at the expense of performance.

My understanding is that the 13900k by default should be reaching at least 30k and even possibly 40k in CinebenchR23. For immediate reference, it is the turbo boost, and ensuing 3.0 max technology + enhanced turbo (to my understanding this is MCE) setting that causes uncontrollable temperature spikes.

Currently, I am running largely default mobo settings. I have long/short power limit to 253w (though upping it to the max ~4000w doesn't seem to cause any issue in my current setup), and EIST as well as Speed Shift on--those two don't cause issues. In this state, my idle temps are fine at 50C, and more importantly even during the Cinebench speed test they do not increase significantly whatsoever. They barely ever crack high 60s or 70s when running the Cinebench test with these settings. 

Everything changes with Turbo Boost and the ensuing mentioned settings that are unlocked with it. Even with just the Turbo Boost by itself, and not the 3.0 or MCE, even idling my temperatures are skyrocketed to the 90s/100C with intermittent thermal throttling. I tried to fix this by lowering the lite load from the 12 it was at, to 9, to 6, then to 3. At the lower lite loads, I was able to get the idle temps slightly down, but they would still skyrocket immediately in Cinebench--though perhaps that is to be expected.

I can't currently get XTU to open, there's some issue going on with the application despite troubleshooting uninstall/reinstall--have a different thread on that going. So, my solutions must come from the BIOS, which I am fine with. But I am very new to overclocking and undervolting. Clearly, the CPU is getting too hot when the Turbo Boost is on, and it's also massively underperforming. Even when I turned the Turbo Boost on and let it run on Cinebench while thermal throttling the entire time, my score only improved from 19k to 26k.

For reference in my BIOS:

-When I set the Load Line Control to advanced (whereas normal lets me set it from level 1 to 21) it show me the AC and DC LL numbers. The AC number is 110 if that is meaningful, as I have seen that discussed in other posts. 

-The Vcore number is 0.858 or so. I don't have it right in front of me.

-The voltage settings are on Auto currently. I have not tried to undervolt or overclock in anyway here.

I imagine that if I could somehow be able to turn on the Turbo Boost family settings, while maintaining a low enough temp not to thermal throttle constantly, that my score would improve? I'm really not certain though,  and am looking for any and all advice on what BIOS settings you suggest that I adjust. Thank you so much in advance.
