Greater than one weekYeah its quite but dont expect a ton of CFM. Probably great for a Rpi3, but wasnt a great replacement for my NAS PSU.

> 3 dayDid the job I bought it for. Very quiet and goes in easy. The box and packaging is ridiculously elaborate and fancy for a $14 fan, but whatever. I hope it didnt affect the price cus if packaging it in a plastic bag would knock a dollar off the price then they should do that cus the packaging now is ridonkulouz.

Greater than one weekHabe den Lüfter als Ersatz für den Hotend Lüfter im Anycubic i3 Mega s gekauft und bin voll zufrieden. Jetzt höre ich nur noch die Schrittmotoren.

Greater than one weekThis little fan is very nice, quiet & well made. Came with quite a few adapter cables, screws & rubber mounts. Used it to replace a dying fan in an internet radio. Moves as much or more air as the original with no noise. Original was a 9 volt fan, but this runs just fine at 9 volts. The adapter cables it came with let me replace the original fan by just plugging it in, no wire cutting / soldering needed. This even comes with 4 wire crimps and a connecter to unterminated wires if you have to re-use the original plug on the old fan and didnt want to have to solder it.

> 3 dayit is not 40mm x 10mm, the 10 mm measurement is more like 11 with out the rubber cushions or 12 with the cushions. not 4 pin pwm fan for motherboards that use a thermal armor assist fan. My bad

> 3 dayThis fan is worth the higher cost over other 40mm fans. I highly recommend.

Greater than one weekDer Lüfter werkelt bei mir als Boardlüfter in einem Ender-2 3D Drucker. Seitdem ich ihn verbaut habe ist er quasi lautlos. Das einzige Problem das ich jetzt noch habe ist, dass ich nicht weiß ob der Drucker an oder aus ist, weil er keinen Mucks von sich gibt.

> 3 dayA great little fan that moves plenty of air and makes very little noise. Would prefer an option to purchase it without the huge box and unwanted extra cables/connectors and adaptors but I guess you cant have everything!

> 3 dayHabe diesen Lüfter in einem Monoprice Select Mini Pro verbaut um den Geräuschpegel zu reduzieren und er passt perfekt und ist auch super Leise.
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.
