My i5-14600KF keeps hitting the power wall and dropping clocks during chaotic fights. Why is this?

Whenever I'm dealing with massive boss AoE attacks, the game hitches noticeably. On default settings, it was a nightmare. I pulled up HWiNFO and saw the CPU spiking to 181W instantly, hitting the power limit and tanking the clock from 5.3 GHz down to 3.8 GHz. I tried switching Windows to 'Ultimate Performance' mode, but that was a mistake—temps shot up to 98℃, triggering even worse thermal throttling. I eventually dove into the BIOS, bumped the Long Duration Power Limit (PL1) to 253W, and applied a -0.050V voltage offset. Using RTSS, I saw my frame times tighten up from a wild 12-35ms swing to a steady 8-14ms. I actually blue-screened during the first load screen because -0.050V was too aggressive, so I backed it off to -0.030V to get it stable. Now temps sit between 75-82℃, and the frequency curve is rock steady. Frame times are now locked in at 8-14ms, though I still worry about long-term silicon degradation.
