    Silence has a price... but it's golden!

    The price may seem high, but the results are impressive!
    I took 5 of them to replace the Pure Wings 2 DC in my Pure Base 600 case, and it's now absolutely quiet: 30% at rest, 50% at 45°C and 70% at 60°C. Even when I'm playing games, the quietness means I can enjoy the game.
    Even at 30% with 5 fans, my speakers, switched on without sound, make more noise. A joy, and above all a good investment.
    For my next set-up, I'll be taking a Be Quiet! case and replacing it with the higher range (Silent Wings Pro) to benefit from the same quietness, but even better cooling with a Dark Rock Pro Elite (and avoid an AIO).

    Zen attitude

    This fan is super quiet and not too expensive, so it's good value for money!
    I got two for the front of my case.
    Great!
    They were available in our branches, thanks to LDLC in Saint Grégoire (35).

    Inaudible

    Fantastic rubber installation method! Very easy to use. A very premium feel to the product in general. My computer is 1 meter away and the fans are inaudible at 50% of maximum speed (~580 RPM). Unfortunately my computer doesn't produce much heat so I can't speak to their airflow performance, I chose them for their quietness and a perfect score on this criterion. Relatively expensive but with a 5 year warranty it doesn't sting.
