My Maxsun MS-Terminator B850M WIFI is throttling the CPU during heavy combat in Nioh. How to fix this?

When facing a huge swarm of enemies, my frame rate would just dive from 60 FPS to 28 FPS, and the stutter was unbearable. I checked my monitors and saw the VRM temps on the Maxsun MS-Terminator B850M WIFI hitting 95-102℃, which forced the CPU to drop from 4.5GHz to 2.2GHz instantly. I tried the 'High Performance' power plan first, but that just pushed the CPU over 100℃ and made the throttling even worse—basically adding fuel to the fire. I ended up gluing some small aluminum heatsinks onto the VRM MOSFETs and set the motherboard fan curve to hit 100% as soon as it hit 70℃. In CPU-Z stress tests, the clock finally stayed between 3.9-4.2GHz without those cliff-like drops. I actually messed up the first time and bumped a capacitor while installing the heatsinks, so it wouldn't boot until I double-checked the wiring. Now the VRMs stay at 68-75℃. The fans are loud as hell, but the performance is finally where it should be.
