How do I stop VRAM overheating in Elden Ring on Onda H610M during boss fights?

My VRAM hit 85℃ in boss fights, causing screen tearing that made dodging impossible. I tried maxing fan speed, but the noise hit 55dB (Sound Meter) without solving the heat issue. I used the GamePP Hardware Sensor Page to switch power management from Balanced to High Performance. This adjusted the cooling strategy effectively. 3DMark confirmed VRAM temps stabilizing between 70-75℃. The system remained stable through 6 cycles of MemTest86, ensuring no performance decay during critical combat encounters.
