How do I stop VRM overheating and physics lag in Pacific Drive?

Driving through complex terrain in Pacific Drive felt like driving on ice. The Biostar B350ET2 VRM spiked to 92℃ per AIDA64, causing visible suspension lag. I tried locking CPU frequency, but that dropped FPS from 60 to 45, making it worse. Then I used GamePP Resource Scheduler to set process priority to real-time. This dropped VRM temps to 78℃. AIDA64 confirmed package power fluctuation stabilized at ±3.2W. The frame rate stabilized at 16.7ms via RTSS, saving my immersion.
