My CPU clocks tank the second I move in the shadows of Splinter Cell Remake. Is the AK500 ARGB failing?

Stealth gameplay is supposed to be tense, but having the game turn into a PowerPoint presentation is just infuriating. The AK500 ARGB struggled with 200W power spikes, causing the CPU to jump from 60℃ to 92℃ in a single second, triggering a hard throttle down to 2.8GHz. I tried lowering the power limit (PL1/PL2), but that just killed my load times and dropped my minimums to 20 FPS—a total disaster. I ended up ripping the cooler off and applying a high-conductivity phase-change pad, then switched the BIOS voltage curve to offset mode, dropping it by 0.05V. In Cinebench R23, my multi-core score climbed from 28,000 back up to 31,000, with peaks capped at 84℃. I actually locked myself out of the BIOS for a bit by undervolting too far, but adding 0.02V brought it back to life. Fans are steady at 1600 RPM. I backed up the voltage profile to a USB, and the config is finally saved.
