Greater than one weekDropped my internal temps by a ridiculous amount. My ram modules used to be burning, now there are at a comfortable 40-50 degrees :)

> 3 dayUsed one of these with a printed adapter on to cool the print head on my 3d printer. It comes with handy cable crimping adapters so you can just cut off the old fan cables and attach this one. This single fan turned my rattling printer into a nice and quiet machine.

> 3 dayDer Geräuschpegel hängt zum einen von der Spannung ab mit der die Lüfter betrieben werden. 7,5 Volt find ich echt leise. 9 und 12 Volt sind schon merklich lauter. Allerdings darf man nicht vergessen Strömungsgeräusche nicht vom Läufter kommen sondern durch ungünstige Luftwege kommen, z. B. zu kleine Luftauslässe. Ich bin mit den Teilen zufrieden, habe auch noch andere Modelle vim selben Hersteller.

Greater than one weekThis is a very quiet fan and comes with hardware and adapters. I have purchased several of these. They are a tremendous value for the price. Great quality - well designed and a moves plenty of air for its size. Kudos to the designers and engineers.
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.
