be quiet! Pure Wings 3 140mm PWM high-Speed White Fan | Speed-regulating Closed Loop Motor | High top-end Speed | Low Minimum RPM | Optimized Fan Frame | Extraordinary air Pressure | BL113 PW 3 140 PWM High-Speed White

These fans allowed me to crank up the RPMs without being bothered by the sound of the fans. Other fans, (Arctic P14s) have an unbearable noise profile at high RPMs. These fans sound good to my ears. It just sounds like air passing through a tunnel as opposed to an HVAC. I run the fans at 90% speed 24/7 and haven't had any issues. (Around 4 months as of writing this review)

No quality issues so far. Just wished these had a daisy chain version so I can link multiple fans together. The fan also doesn't include a CPU fan metal clip, but it comes with 4 screws. Note on installing fans: the fans don't have threads in the plastic casing, so you have to create the threads which the screws are meant to do, and it can take a bit of force. I suggest pre-threading the fan before mounting it. Make sure you have the correct direction before attempting it.

Sehr schöne und leise Lüfter. Klare Kaufempfehlung.

Como es blanco, se le va a notar más la suciedad pero no importa, limpiándolo se arregla

German products are synonymous with quality, no noise, stable operation, highly recommended.
