Super silent and soooo easy to install
A fan on my PC started to click, so I knew I had to change it.After a bit of research I found that these were the best option, they may not be the cheapest, but they're well made and are super silent.They arrived quickly (as an aside - great packaging). They were really easy to install, just four screws and a plug and I can honestly say I should've bought them years ago. They're totally silent and they've made working next to a whirring pc a dream. I can actually concentrate !Couldn't be happier with the purchase, and although a bit more expensive, these will def last a long time.Highly recommended.

Great fans
Great fans at a great price.

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.

How quiet is quiet?
Have loads of these, whilst the fans are themselves quiet the air they push around a case is not.

Very very good quality!
Omg, I am so impressed! I think Bequiet is the best!I have bought a Noctua and a Bequiet 140mm both. And i like the Bequiet more

-10 degree difference
Was using standard 140mm's that came with case.. setting up a good fan curve and replacing with these resulted in a -8 -10 degree difference, very good.
User
Easy to install
The instructions manual is hidden under the fan package , come with 2 sizes of the mounting and the screws in the accessories box.Depend on which mounting you prefer , installation was very easy and quiet

اخذت المنتج للتجربه ايام الخصومات وللامانه المراوح جدا هادئه مقارنه بمراوح ثانيه تستاهل سعرها واذا كان عليها خصومات لا تفكر بغيرها بس قبل اي شي تأكد من حجم المراوح وانها تركب على جهازك او لا

Silence, performance, point barre.
J’en avais déjà 4 et que dire à part silence rime avec performance !Franchement, ça coûte un bras même en promo, mais ça vaut le coup pour qui veut un airflow incomparable dans un silence quasi impérial.En promo à 26€, ma foi c'est à peine 1€ de plus que le prix que j'ai eu pour les 4 autres d’occase. Que demader...Seul regret, l'obligation de cet ineffable sticker dégueu sur la partie montants. Quand tu montes en air entrant dans un aqua, c'est vraiment dommage.
