be quiet Silent Wings 4 Black 140mm PWM Fan Noise Level 13.6 dBA Max, Airflow Upto 51.3 CFM

I have an air cooled system. Been running Noctua fans , thought these were awesome until buying these be quiet ones. The build quality is second to none, very impressed. Screwless mounting was really good and precise. As in the name, it runs very quiet.
I am very pleased with these fans. The only downside is that they need more wattage to run. I have an air cooled system.

Got this product as a back case fan, simple installation the vibration absorbing makes it quiet. Got this product as a back case fan, simple installation the vibration absorbing makes it quiet.

bought this fan as a back case , wanted a quiet fan so it wont addon too much dB for the overall fan noise, this is a very good choice with the vibration absorbing mount which comes with it the noise level is very low. i can hardly hear it, especially i have my computer next room to my little 4yrs old. will consider to purchase more to replace the 3 front case fan which comes with the corsair case. bought this fan as a back case , wanted a quiet fan so it wont addon too much dB for the overall fan noise, this is a very good choice with the vibration absorbing mount which comes with it the noise level is very low. i can hardly hear it, especially i have my computer next room to my little 4yrs old. will consider to purchase more to replace the 3 front case fan which comes with the corsair case.

I used these to replace the stock fans on a Fractal North and the difference is night and day! These don't spin as fast but they push a lot more air and my temperatures are very healthy in the system. They are ridiculously quiet at max speed I used these to replace the stock fans on a Fractal North and the difference is night and day!

Some of the best fans out there. Some of the best fans out there.

I was really happy with these fans.

The build quality is great and they're very easy to install.

Great fans, especially if you're not looking for rgb. They are very quiet while running and are a significant upgrade from the fans that came with my case. I was really happy with these fans.

Great fans, easy to install and very quiet. Added them to top of my PC case but considering replacing another two 140mm fractal fans with these be quiet ones as well.

This is second time I have used these case fans, robust, quiet and good looking not cheap but worth it. This is second time I have used these case fans, robust, quiet and good looking not cheap but worth it.
