> 3 dayAmazing noctua fans always are. Replaced the ender 3 pro 40mm fan with this and omg what a world of difference. If you get this and stepper dampers you can hardly hear the 3d printer running even when in the same room super quite now amazing.

> 3 dayI installed two of these on my Wanhao i3 3D printer. I was hoping to see some noise reduction but what I didnt expect was -- silence. These two babies, plus a large fan to replace the fan in the power supply and control unit, and the i3 has turned from the noisiest printer to the most quiet in my small print shop. Should have done this a long time ago.

> 3 dayHo utilizzato questa ventola di spessore 1 cm per dissipare il calore del mio SSD M2 della scheda madre già con il suo dissipatore in alluminio incluso con la scheda madre stessa ASUS ROG Maximus X Code : la temperatura si è abbassata di circa 4 - 5 gradi portando la temperatura a riposo da 41 gradi circa a 35 - 36 gradi. Ho installato la ventolina con supporti adesivi in nylon che si utilizzano per circuiti stampati - schede elettroniche. Successivamente ho voluto fare una ulteriore prova con la stessa versione di ventolina Noctua ma di spessore 2 cm e cioè il modello NF A4 x 20 con la sorpresa positiva di ottenere ulteriore abbassamento di temperatura a riposo di altri 3 - 4 gradi portando quindi la temperatura del SSD M2 Samsung 970 PRO a circa 31 - 32 gradi . Eccezionale ! Era quello che volevo ottenere con una ventolina piccola, silenziosa e soprattutto di buona qualità ed affidabilità come la Noctua sa fare.

Greater than one weekCould do with some more rpms to keep the flow going. Is just good enough but if you struggle for cooling already it may be a weak point for you

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.
