My DeepCool AK500 WHITE can't handle Novigrad in Witcher 3 Next-Gen, causing huge clock drops. What gives?

I noticed these annoying micro-stutters every time I turned the camera quickly, which is a total immersion killer in an open world. The DeepCool AK500 WHITE ARGB just couldn't keep up with 150W power spikes, and my core temps hit the 98℃ ceiling, tanking my clocks down to 2.6GHz. I tried enabling power-saving mode in Windows, but that was a joke—it didn't lower the temps and my 1% lows dropped from 55 FPS to 38 FPS. I realized the cooler had hit its physical limit. I ripped the cooler off, applied high-conductivity phase-change thermal paste, and manually capped the PL1 power limit at 115W in the BIOS. In Cinebench R23, my multi-core score jumped from 22,000 back up to 24,500, with peaks capped at 86℃. The power cap actually added about 2 seconds to my load times, but enabling XMP memory overclocking made up for it. Fans now sit at 1700-2100 RPM and RAM temps stay between 52-58℃.
