Is VRM overheating causing frame drops on MSI A520M-A PRO?

Whenever a giant Boss unleashed a massive attack, my FPS would tank from 60 down to 25, which was incredibly frustrating. Checking the sensors, the VRM temps were hitting 102-108℃, triggering a massive CPU downclock. I tried lowering the core clock via software, but that just killed my overall performance by 20% without fixing the root cause. I eventually went into the BIOS and capped the long-term power limit (PL1) at 65W, and I literally zip-tied a tiny 4cm fan onto the VRM heatsink. In RTSS, the clock finally stabilized between 3.8-4.1GHz, and the drops stopped. I was actually worried the fan wires would mess with my RAM slots, but a bit of cable management fixed that. VRM temps now hover around 82-87℃. OCCT confirmed the clocks aren't bouncing anymore, and the input response finally feels snappy again, though the BIOS cap is a necessary evil.
