    Highly efficient, silent fans

    To complete a Base 500 box from BeQuiet, they do a great job and are especially quiet.
    Inaudible at 1 metre, I sometimes even forget that the computer is on.

    The right balance between PRICE and QUIETNESS

    The PURE WINGS 2 offer good value for money for case ventilation compared with the SILENT WINGS 2 and the new SERIE 3.
    I hesitated for a long time to pay more for the silence, but at 2 or 3 times the price (from 12 to 25 to 36€ each), I didn't take the plunge, even if it lasts over time.
    In other cases (for a VENTIRAD replacement or on a WATERCOOLING RADIATOR), I would have spent more for the static pressure/noise ratio, but for the box ventilation.
    I didn't get the RGB models, which aren't very good in terms of effect, so maybe I'd use RGB grilles instead.
    The noise level is almost inaudible, the air volume level is quite low, but if you put several fans in an open case with a standard configuration, it's perfect (the sensor indicates a case temperature of -2 degrees compared with the old fan, which was 120 and noisier).

    Don't forget to buy a Y cable if you are installing a pair of fans on the front (so that the 2 fans have identical PWM control via the CM).
