Greater than one weekMade a huge difference in noise levels, the stock fan had a loud noisy sound with the case on (much improved with the case off), but putting the Noctua with the included voltage limited pretty much solved that. Its as quiet as the idling Mac mini next to the NVR and I dont have to hide the NVR now.

> 3 dayinstallata sulla hot end della mia stampante 3d, ha drasticamente ridotto il rumore. Potrebbe essere necessario un saldatore elettico se dove si installa si è sprovisti di un cavo simile ai tanti inclusi nella confezione della ventola.

> 3 dayThe fan works perfectly but the mounting options weren’t perfect. Nothing four nuts and bolts couldn’t fix though. Overall happy with this fan. Extremely quiet and effective.

Greater than one weekI was looing for a quiet fan for a NAS that I was building. My goal was to make the NAS as silent as possible. This fan is barely audible and moves a sufficient amount of air to keep the NAS cool. A great buy.

> 3 dayMit diesem Lüfter habe ich meinem TEVO Black Widow das Gekreische abgewöhnt. Zumindest für die Hotend Kühlung. Da der Lüfter 12V benötigt habe ich noch einen preiswerten Stepdown-Regler vorgeschaltet und diesen auf 11.5V eingeregelt. Zusammen mit zwei weiteren Noctua 60mm und 120mm Lüftern für Netzteil und Platinenbox ist der Drucker nun flüsterleise.

> 3 dayPackaging great. Fans are almost silent. Replaced 28P Switch fans with these. Wow what a difference. Stock fans were like jet engines.
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 FLX is a highly optimised, premium quality quiet fan in 40x10mm size. Smooth Commutation Drivetechnology and Noctua’s reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor and OmniJoin Adaptor Set, the NF-A4x10 is a premium choice for the highest demands.
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

|---|---|---|---|
Flow Acceleration ChannelsThe NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 BearingThe NF-A4x10 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Integrated Anti-Vibration PadsIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Reduced motor hub size
Thanks to its streamlined, compact motor design, the NF-A4x10"s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10"s superior airflow and pressure performance.
