Hi all!
I've seen a couple of similar posts here, but nothing that maps well enough to the problems I've been having, so I figured I'd start a new thread and hope it works out.
Some stats to start off with: i9-10900K with a 360mm AIO cooer on a Z490 Taichi Motherboard running a 4090 GPU on a Corsair RM850X PSU. The screenshot I posted with summary data from HWiNFO64 should speak to the rest of my system specs.
My setup has been going through periods of alternating performance issues, during which nearly any kind of effort leaves it struggling to catch up. For example, mousing over app thumbnails in my Steam library has a significant latency to the zoom-on-hover effect, and games that I've previously had no issues running start running with a near-countable number of frames. Periods of poor performance can last several weeks before returning to normal out of nowhere and running like a dream for another several weeks before dropping precipitously with just as little warning.
I started diagnosing things using Intel XTU, which was the first time I noticed the EDP Throttling flag. During periods of poor performance, it was activated almost immediately upon reboot, but when my computer was working properly, it didn't show up at all. This most recent period of poor performance has started off without the XTU EDP Throttling flag, I started digging into other tools beyond XTU, like ThrottleStop and HWiNFO64 (screenshots from which are attached to this post). I didn't include the TS Limit window in the screenshot, but it's got ONLY a near-constant red EDP Other block in the Ring section, whereas HWiNFO64 shows IA Limits from Max Turbo Limit and Turbo Attenuation. More importantly though, it shows Ring Limits due to EDP-type constraints in line with those shown by TS.
Looking through the other EDP-related issues on this and other forums, I've checked things like the ICCMax Values, etc., and they're already set as high as possible, so I'm running out of steps to take next.
A couple of interesting notes:
My current guess is there's just a bad sensor somewhere that I need to disable, but I don't want to accidentally fry something. I barely know anything about Computer Hardware/Engineering, so ELI5 responses are welcome!
Thanks,

A couple of interesting notes:
- I tried several different Benchmarking approaches, all of which get throttled to just under 800MHz, with core temps not to barely exceeding 30 deg C
- I can physically distinguish between periods of poor performance and acceptable performance by the amount of heat being radiated from my computer. If it's working properly, I can feel the hot air being vented from my PC under stress (while keeping temps below 60-70 deg C in monitoring software)
- I mentioned it before, but these swaps between poor performance and proper performance are infrequent. If my computer is terrible, it's terrible for a long time. If it's good, it's good for a long time, not a lot of switching back and forth.
- I'm not looking to overclock anything. I just want my computer to work right again.
