Review on case fan be quiet! Silent Wings 4 120mm PWM, black by Mateusz Michalak ᠌

- Can't hear at all at medium speeds - At high speeds, the movement of forced air is audible - I bought it to replace dropsy turntables (3x120mm), of course this is heaven and earth. - If earlier it was heard how the turntables accelerate for a while to cool the processor at 100% load, now I don’t even know at what moment this happens (temperatures are normal, even though the max speeds of the old turntables were higher). - If you do not take into account the price, I definitely recommend it.
