How do I stop VRM overheating from causing frame drops?

Entering Huaguoshan, my screen froze as the Maxsun MS-终结者 B850M WIFI VRM spiked past 85C. I tried adding a heatsink, but it only increased noise without lowering temps. I then used GamePP Hardware Sensor to remap the fan curve, raising RPM from 1500 to 1800 at 80C. After this change, AIDA64 monitoring showed core temps stabilizing at 72-78C. Frame time converged from 12-18ms to 8-10ms via RTSS, eliminating the stutter. The system now runs cool and stable, saving my gameplay from thermal interruptions.
