Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and an AAO standard frame, the NF-A4x10 5V is a dedicated 5V version of Noctua’s highly optimised, premium quality quiet 40x10mm fan. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and the OmniJoin Adaptor Set, the NF-A4x10 5V is a premium choice for demanding 5V applications.
Many devices such as network or storage solutions use 5 volt 40mm fans. With the same operating voltage and the included OmniJoin adaptor set that makes it compatible with proprietary fan headers, the NF-A4x10 5V is ideal for replacing noisy or broken 5V 40mm fans.
Please Note: Being a 5V fan, the NF-A4x10 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
Integrated Anti-Vibration Pads
Integrated 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.
The 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.
Reduced motor hub size
This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance.
Scope of delivery
Flow Acceleration Channels
The 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.

Ergebnis - selbst bei 5V ist der Noctua-Lüfter doppelt so leise, wie der mitgelieferte auf 3V. Das Mehr an Kühlleistung wenig messbar, aber sofort fühlbar. Habe ihn dann über die Pinbelegung beim Raspberri auf 3V runtergeregelt: Da kann ich den Noctua kaum noch wahrnehmen. Sehr geil!
Lieferumfang: Viel mehr als ich vermutet hatte. Für nahezu jeden Einbau liegt noch Montagekleinteile und/oder Adapterkabel bei. Das erklärt auch den kleinen Mehrpreis.
Fazit: Für das Geld absolut genial. Wer einen kleinen & leisen Lüfter sucht, sollte nicht weitersuchen - hier ist er richtig.

OK there are a lot cheaper fans, but you get what you pay for. I've used Noctua fans/sinks on a couple of PC projects and know that they're well made, solid products.
Now, after 19 months of use, it's so much noisier. It has a really annoying mechanical whir.
It's still in the same CCTV recording box, and it is on constantly, and over the last few months it's gotten louder to the point where you can hear it over a conversation or from another room.
I've been vacuuming dust off it, but it hasn't helped.
With 17 years MTTF (Mean-time-to-failure) I would have expected it to remain quiet for much longer than 19 months.
I've ordered a replacement now, but will see if this noise is something that's covered under the manufacturer's 6 year warranty.
Original Review 3 May 2018:
Needed a fan to replace a noisy one inside a CCTV recording box.
This one came with various connectors to get it plugged in, and it's so much quieter than what was in before.
It comes in the box with a range of connectivity options. It has a number of single-use splice connectors with an epoxy capsule inside (you join your cables then press the connector shut and it seals them) if you prefer not to solder your cables, so you can attach almost any plug to this with almost no tools at all.
I connected mine to an unused internal USB header for 5V power and it has been running that way ever since. I don't bother speed controlling it or monitoring the rpm - it just runs all the time from USB bus power.
Perfect addition to any passive system or heatsink that could use a little extra cooling help.
bought two 5v fans to cool my duet 2 on my cnc machine. look good in nice shiny box with extension cables, mounting screws and other bits and pieces. plugged fans into board (black and red wires only, removed original 3 pin connector block, inserted original pins into duet 2 pin connector block, double checked polarity, taped yellow pin out of the way using electrical tape) and nothing. tried other ways of powering fans and still nothing. complete waste of money. have ordered 5 winsinn 40mm fans for 70% the cost of one "premium" noctua fan. not impressed and wouldn't waste money on the brand again
