"giving noctua a run for their money"
As typical with be quiet!, these are extremely quiet fans. Not being pwm means that they are even quieter since there are no switching noises whatsoever. Either way, that isn't a problem since anybody bothering to read the review of a case fan most definitely has a motherboard that supports voltage regulation of these types of fans. Even at top speed they are below 20dba, hitting only 18.8db, so i'm more to happy to sleep with them on in my bedroom only a few feet away. And the rubber mounting points are a nice touch of course. All in all, i'm very happy with them, and i'm confident they give the much more expensive noctua's a run for their money. If not just check out the reviews from the overclockers club

Recommend looking elsewhere
1st star for it just being fulfilled by outletpc, which i cannot praise enough2nd star for it being the color black, and not pooh pooh colordoes not meet expectations for a 20$ fan. Its actually a ~10$ fan, with the other 10$ covering the shipment from deutschland.Brand new fan and already there is added noise from the bearings. Simply and gently with a spin of the finger there is slight audible raddle/grind, which will only get worse over time and wear. For the same price you could grab a noctua fan or the premium edition be quiet fan that is lower in dba and comes with anti vibration rubber corners on newegg (for some reason it is 44$ on outletpc.

They're okay.
So quiet you wont even know the machine is one but rpms are low, really low keep that in mind for air flow.
By Alberto Esteban
Really quiet and provides enough airflow
The fan works well. There is no trade-off of airflow for noise. It provides adequate airflow, and was easy to install. I'm definitely a fan of be quiet!

In a dead quiet room, you have to put your ear right next to it to hear it. Moves a lot of air.

Air-cooled perfection
Beautiful, quiet, and they move lots of air. I purchased two of these to put in the front two slots of an nzxt s340 elite case, and they were a breeze to install, though maybe my own cable management skills could use some work. I'd say i'd gladly buy these again, but i think the two i have are going to last me a long, long time.
