How do I fix frame time jitter caused by the Valkyrie V360 Lite pump?

The pump vibration caused frame times to jitter from 8ms to 12ms per RTSS. Increasing voltage made the noise worse at 42dB. I used GamePP Hardware Sensor Page to lower pump speed to 1800 RPM. AIDA64 confirmed temps stabilized at 68℃ and frame time locked at 8ms. The system is silent now, allowing me to export my stable configuration for future sessions without any stutter.
