Elden Ring is stuttering during open-world exploration on my Galax B760M D4 due to VRM heat, help?

Exploring the Lands Between is great until your FPS suddenly dives from 60 to 32; the stutter is just jarring. I checked my monitors and saw the VRM on the Galax B760M D4 Black Knight hitting 94-100℃, which forced the CPU to plummet from 4.4GHz down to 2.1GHz. I tried 'Maximum Performance' mode in Windows, but that just pushed the CPU over 100℃ and made the throttling even worse—basically throwing gasoline on a fire. I ended up gluing small aluminum heatsinks onto the VRM and setting a custom fan curve to hit 100% speed once it hits 70℃. In CPU-Z stress tests, the clocks finally stayed between 3.8-4.1GHz without those cliff-like drops. I actually accidentally bumped a capacitor while installing the heatsinks, so the PC didn't boot the first time, which was a heart-stopping moment. Now the VRM sits at 66-72℃. The fans are loud as hell, but the performance is finally verified. Motherboard temps are around 52-57℃.
