be quiet!Pure Wings 3 140mm Quiet PWM High-Speed Case Fan | Speed-regulating Closed Loop Motor| Extraordinary Air Pressure | BL109

Push good amount of air and fairly quiet. Perfect for case fans.

These perform exactly as advertised. At full speed, they do roar a little bit it could be due to the restriction of the front panel on my Coolermaster Q300L. Up to about 80% speed, they are very quiet, just a low hum.

Well made, and keeps things cool

My Be Quiet DX500 came with the previous generation fans, and I wanted to add one more so this seemed like the way to go. I'm doubting if I needed the high-speed version as it did seem fairly loud on the default fan port settings. The case came with 3x Pure Wing 2's with 3 pins, and this looks very similar but has extra blades and a 4 pin connector. I had two front and one back/exhaust setup and this new one went in the top of the case. However, I'm thinking I need to swap this high-speed one to the rear/exhaust position. Once I got the fan profile setup to include this new fan, the sound profile does seem better. All of the fans seem to run a little slower rpm with the added airflow this new fan brought. Overall, I'm very happy, though I do wish this included the foam corner inserts. As the fourth case fan in this build, it is a good addition but maybe a bit too much.

Quiet and strong fans for both intake and exhaust.

Much quieter than stock fan. Long fan cable also which is was nice for my use case.

On first glance, they look to be quite well built. I haven’t tried these as I switched to Noctuas last minute, but people say they perform pretty well for the price.

Fantastic fans. Quiet, powerful, great value. CPU is air-cooled and installed 2 of these on the top as exhaust. Dropped my CPU core temp a good 5-7C under load, ran Prime95 for a good 45min without touching 90C.i7-7700MSI z270-a Pro32gb DDR4 @2666RTX 3050 OC
