Review on ARCTIC F12 PWM PST CO - High-Performance 120mm Case Fan with Dual Ball Bearing, PST and PWM Technology - Grey by Adam Listopad ᠌

Do not forget about the impact that all sorts of gratings, nets and other holes through which the air flow passes. This is including them, like a wind musical instrument, they create all sorts of noise that tires us so much. Whereas the valve connected outside the system unit is absolutely inaudible. Especially if it's a fan from Arctic Cooling. I changed all the valves in the system unit and added additional valves from this company. And to exclude vibration transmitted to the case, do not forget about rubber nails!
