Be quiet! Ventilador Pure Wings Pwm 140 Mm

Very quiet fans, as well they should be. Just FYI, you can't see the be quiet branding at all when they're spinning.

Quiet and Cool - That is all you need. This is quality.

A fairly quiet fan. Lives up to the brand name! Seems to be doing its job well (at the very least, sufficiently)

Quiet fans. I did have a bit of trouble with these fan screws and my cases fan rails, but eventually I got them in. Just enough extra airflow to ensure the system stays cool.

I bought three of these fans to solve a case fan noise issue with my NZXT H7 Elite. Installation was easy and flawless, and only took a few minutes. Upon booting my PC with the new fans in place, my system sounds 90 to 95% quieter than before. I highly recommend these fans for anyone who's having similar problems, or just quieter case fans in total
