Awesome fans
Awesome fans, well built and speedy selector is great. Extremely quiet and great airflow. Appearance is very stealthy and in all black which I like. Expensive but worth it.

Look no further if you want efficient, quiet cooling.
Brilliant. Easy to install, and extremely quiet. Came with a bunch of extra fittings for different purposes. Will definitely return to this brand in future.

Quiet and effective
This fan has 3 levels. The highest level is too loud for me so I don't use it but the 2 fans still keep the temperature of my 10-core 3-4 GHz CPU under 80°C under sustained full load. The non-pro version would have sufficed for me.

とにかく静か
通常のSilentWings4にはないPWM最高回転数を設定するスイッチがあり、さらに自分のPC環境に合った設定が出来ます。より静かなPC環境を求める方におすすめ出来る一品です。

Exceptionnel
Performances exceptionnelles au niveau du refroidissement et du faible niveau sonore (vraiment silencieux!)La version Pro est encore plus performante que la version standard en 140mm. Bien sur c'est plus cher mais les performances sont au rendez-vous.En 140, vous avez 3 références principales dans la série Silent:- Silent Wings 4- Silent Wings Pro 4- Silent Wings 4 high-speedSi vous ne savez pas laquelle choisir, prenez la version standard (non Pro), elle conviendra dans la grande majorité des setups. Si vous avez le budget, optez pour la version Pro. Et si vous avez besoin d'un flux d'air rapide et permanent, vous pouvez opter pour la version High-Speed mais vous aurez une augmentation significative du niveau sonore (plus du tout dans ce qu'on peut attendre de la série Silent...)La version Pro a un switch qui permet également de régler le mode vitesse sur 3 niveaux. C'est le meilleur choix si vous souhaitez une performance maximale avec le minimum de niveau sonore.

High quality and silent
I put two of these on my NZXT Kraken Z63 and omg it made such a huge difference. The stock fans of the Kraken were very loud and their performance was so bad that the pump had to work extra hard causing even more noise and the vibration could be felt on my desk. Even with headphones on I would constantly feel the vibration from the pump. Now with these two fans, they are so silent and the most importantly the pump doesn't have to work as hard, so there no more vibration. I can't believe how silent my computer is now, even with the CPU at 100%. Be Quiet! is amazing. Thank you
