Hoping someone comes out with benchmarks for the best cpu cooler for 5900x. then whatever fails set to -10. Here was mine at 4. But since you're also running a sff system my suggestion is to let the limits at stock, use curve optimizer to undervolt and squeeze out last bit of performance, and tweak your fan curve to keep constant below 75C, and really ramp up hard above 85C. 075 to 0. Next, your cooler master CPU cooler is pretty mediocre so you could consider upgrading that to a better cooler or possibly an AIO. 2ghz instead of 4. My 5900x took all the curve ever, and performance still dropped above +100, so it seemed to confirm that step 1 accurately identified the boost threshold for the chip overall as opposed to single cores that might be able to go slightly higher given more space to roam. I have a 5900x, 3090 FE, Arctic liquid 360mm and a lian li 011 XL case. Also check voltages with all 4 runs, and see if it actually did the undervolt. Shouldn't an undervolt lead to lower or at least the same temperatures as stock settings, as lower Voltage means less Power means less thermal energy?

Don't undervolt until you've played with the Curve Optimizer. and i think i will be forced to lower the power a bit to get good temps (for my mindset) NH-D15 is the best air cooler money can buy. The problem is my best cores on best ccd are unstable with everything higher than +25mhz -0 curve optimizer. But until then the boost was up to 4950 and temps were down a good 10c as was the total power consumption. In general, AMD Ryzens seem to like undervolting (good, more even performance with less heat), but the reason especially you should undervolt is, symptoms point to your system (likely VRM) possibly not being able to feed 5900X and reducing power consumption would likely lead to better performance.
