My system keeps crashing during high-load scenes in The Last of Us Part II on a Colorful H610M-K; how do I stop this?

Honestly, trying to run a AAA masterpiece on an entry-level H610 board is just asking for trouble. The VRM on the Colorful H610M-K was hitting 105℃ under full CPU load, causing the voltage to ripple until the system just gave up and rebooted every 10 minutes. I tried stuffing three 12cm fans in my case blowing directly at the board, but temps only dropped by 5℃—a pathetic effort given the board's terrible heatsink design. I eventually went into the BIOS and hard-capped the CPU PL1 and PL2 power limits to 65 Watts and disabled all multi-core enhancement boosts. In OCCT stress tests, the VRM finally stabilized between 88 - 92℃, and it ran for two hours without a single error. I did lose some performance, with minimums dropping from 45 FPS to 38 FPS, but that's way better than a reboot every ten minutes. CPU temps are now 75 - 82℃ with fans locked at 2000 RPM. I exported these conservative settings to a profile, and the fans are steady at 2000 - 2100 RPM.
