be quiet! Shadow Wings 2 (BL086) 140mm Silent Computer Fans

Super quiet and pushes enough air out of the case.
I am satisfied with build quality and airflow.
The airflow is very good for a low speed.
The fan is only 900 RPM so don't expect it to be able to push air through a fin stack on a radiator.
The speed is too low and the airflow is weak.

Effective and quiet. Great fan.
The Be Quiet fan has a nice build quality, ample cable connector length.
Even spun up to max, they are nearly silent.
I even set the speed to its max 900 rpms and it was super quiet.
They are very well made and the rubber bumpers really help to silence any potential vibrations.
