How to kill the high-frequency noise on the V360 pump?
Process priority won't do a thing for a physical noise issue. This pump whine was literally brainwashing me; in a quiet room, it was louder than the actual game combat. The V360 defaults to a locked 12,0V pump speed, churning out a piercing 45,0 - 52,0 dB while water temps fluctuated between 32,0 - 38,0C. I tried dropping the pump speed to 50% via software, but my CPU hit 90,0C and the game crashed instantly—kind of a funny fail, honestly. I went into the BIOS and switched the pump to 'Smart Mode,' letting the voltage dynamic shift between 60,0 - 80,0% based on CPU temps, and set the rad fans to a silent profile. My decibel meter showed the noise drop from 52,0 dB to 38,0 dB, with cores staying at 75,0 - 81,0C. I noticed some bubbling sounds after the first tweak, but tilting the case to bleed the air fixed it. Water temps are now a steady 35,0 - 39,0C. Logged all the data and it's finally quiet.
