> 3 dayProduct seems of very high quality, extremely quiet and lots of adapters. BUT no doubt the insane box in comes in is surely the most expensive part of the product. This kind of packaging should be reserved for store shelves. For online purchase, Id prefer a brown box as small as possible. I can get all the graphics and infos on the website since im already online to buy this.

> 3 dayThey are very quiet. I installed them on my 3D printer. Unfortunely, when I can back to it after an overnight print, I found the wires had snapped off on the 3-pin to 2-pin adapter they supplied with the fan. It caused a bad case of heat-creep, and for my filament to snap off and a print fail.

> 3 dayMolto bene, ma non benissimo. Silenziosa, ma il flusso ne risente. Molti accessori, packaging top, ma un po cara.

> 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.

> 3 dayI bought this to replace my DVR fan in my cctv system, with a view to make the system quieter. This made absolutely no difference at all. In fact it was actually a lot louder than the one that came with my DVR. The item is very well packaged, perhaps too well packaged. It’s the sort of packaging you’d expect with a smart phone and let’s be honest it could have come in small paper envelope and they could have cut down on the cost. All in all it wasn’t worth the money and I will be returning it for a refund

Greater than one weekDo not forget to buy a Buck Converter. I connected straight to 24v and my fan works at the highest speed. What makes it a bit louder than it should be

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.
