Review on 🌀 ARCTIC P12 PWM PST 120mm Case Fan: Pressure-Optimised, Quiet Motor, PWM Sharing Technology - Buy Now! by Ae Rim Ra ᠌

Deepcool matrexx 55 has 5 arctic fans in the whole case (3 * 140 F intake version, 120 P exhaust version on the back side and 120 F exhaust version at the top) . At idle, you can't hear it at all. Under load, the sound of the air flow does not bother at all. Take F for blowing in, P for blowing out. In short, you won't find better value for money. : after half a year, a little white howl began to howl from 30% of the load-657 rpm.
