I'm getting annoying frame drops during high-speed runs in Need for Speed with my V360 MERLIN, why?

While pushing the limits on city streets, my CPU core temps were bouncing wildly between 82-88℃, which caused the clock speeds to jump erratically from 4.8GHz to 5.2GHz. This instability translated into a micro-stutter every few seconds, making the driving feel clunky. I initially tried enabling 'Ultimate Performance' mode in Windows, but that was a disaster—temps shot up to 92℃ and triggered aggressive thermal throttling. I eventually dove into the BIOS and tweaked the fan curve to hit 100% full blast at 75℃, while simultaneously setting a core voltage offset of -0.05V. Running AIDA64 stress tests showed the peak temps were finally suppressed to 76-81℃, and the frame time variance tightened from a messy 14-32ms down to a smooth 8-12ms. I did notice a weird resonance noise from the fans at low loads after the first tweak, but dialing the speed back to 800 RPM below 50℃ fixed that. Now the CPU holds its boost clock even at 90% load. Confirmed via the motherboard control panel that the strategy is sticking, with frame times locked at 8-12ms.
