> 24 hourPremium packaging and accessories. Comes with a low noise adapter (which I suspect is a cable with built in resistor), rubber standoffs to manage vibration, several cable adapters, and an awesome box.

> 24 hourGot this fan because it was so highly recommended in the reviews here and after reading the specs on the fan I was I placed my order. Shipping was prompt and packaging was awesome with all the extra parts needed for installation. I installed mine by cutting the power wires at about 4 inches and splicing it to my plug using the included wire splices.

> 24 hourHo montato la ventola sul dissipatore dellE3D v6 sulla mia stampante 3D in quanto la ventola che avevo precedentemente su purtroppo lho disintegrata facendo poca attenzione nel montaggio/smontaggio.

> 24 hourI bought this as a replacement fan for my TM-D710A radio. Its dead silent and moves enough air to keep the radio cool.

> 24 hourAllinizio ero preoccupato perché non sentendo alcun rumore credevo di averla collegata male, invece era funzionante ma impercettibile come rumore! Noctua è una garanzia!

> 24 hourTrès bon produit, très silencieux, débit dair inférieur à un ventilateur classique (silence oblige..) belle finition avec les patins anti vibration dans les angles et les attache en silicone.

> 24 hourVery nice and quiet. Used these in a push and pull configuration to upgrade my old 3d printer fans. These work great. They perform on par with the old fan (I dont know the model) on volume of air coming through but the noctua fans are dead silent while the old stock fan could be heard on the second floor of my house while my printer is in the basement. Very happy with the purchase. Noctua never disappoints.

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.
