    Well I asked them many times for test samples so I can do a test and compare them with the rest of the fans which I already tested and added here: and here:

    About the fans…
    I always use fans which are featuring PWM control and offer high speed operation with high airflow and high static pressure such as Cooler Master Exaclibur (for example).
    At cold days I let the fans operate at auto and they rarely reach 1000-1200 revolutions per minute. In that range they are quiet as a whisper.
    At warmer days I increase the revolutions manually and in that case I make a nice environment so my hardware can work properly. Of course sacrificing the noise.

    Anyway I prefer to sacrifice the noise instead of my hardware 🙂

    Waiting for this to use in push / pull configuration for my Kraken X60.
    @ Dk_vr — Why need a test sample, it’s the same fan as on the Kraken X60 and there are plenty of reviews…
    NZXT takes forever though to get these on the market! I buy an X60 and can’t buy additional fans for it, which is quite bad. FYI the fans @2000rpm are loud indeed, but they do push a lot of air! When using silent and a sensible custom profile with the Kraken X60, i.e. fans at around 1000 rpm for low load everyday use, they are perfectly quiet. That’s why I won’t bother getting some e.g. Noiseblocker PK-3 or Akasa Viper or whatever, b/c they either push less air or look stupid or are anyway as loud at high rpm. If anyway knows a fan that is significantly better, no PWM whining or rattling (which the NZXT they don’t have at all), and come at much improved noise – I am happy to listen. I haven’t found any (UK).
    Scythe Slipstream have stupid (Scythe, if your are listen – why???) 120mm mounting holes, would otherwise be a nice fan, but pointless with 140mm rads. And then maybe Yate Loon D14SH-12, but difficult to get here. Corsair only 140mm “AF”=air flow, i.e. low static pressure. Silverstone maybe…
    My 3 cents 🙂

    There wont be review. NZXT are not providing me test samples.

    Seems a bit noisy, let’s wait for the review XD
