How to stop micro-stuttering in Death Stranding 2 with V360 Lite?

While crossing rugged mountains at 4K, I noticed an irritating slight tearing and micro-stuttering that broke the immersion. I tried setting the pump to full speed in the BIOS, but the resulting resonance noise made the entire chassis shake, which was a terrible experience. Using the GamePP Hardware Sensor, I monitored the fluctuations and micro-adjusted the pump voltage to a fixed 1.34V per GPU-Z. RTSS confirmed frame times converged from 14-22ms to 13-16ms, and water temperature stabilized at 33-37℃ per GamePP.
