How to fix the Valkyrie V360 MIST pump noise in RE Village?
While exploring the creepy village, all I could hear was this annoying high-pitched buzzing in my ears, which totally killed the horror atmosphere. The Valkyrie V360 MIST pump stays at 12V in full-speed mode, causing violent resonance even in low-load zones between 40℃ - 50℃. I first tried adding rubber dampeners to the case, but the resonance point was still there, so I decided to perform 'surgery' in the BIOS. I switched the pump from full speed to smart mode and locked the voltage range between 8.5V - 10.5V, while syncing the fans to the liquid temperature instead of the CPU temp. Using a decibel meter, the idle noise dropped from 42dB to 31dB, and full-load temps stayed between 72℃ - 78℃. I did have a scare where the pump almost stopped when I dipped the voltage to 8V, so I bumped it back to 8.5V for stability. Liquid temps are now stable at 32℃ - 36℃. I toggled the mode via the control software, and the coolant stays right at 32℃ - 36℃.
