The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. It takes state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame or Flow Acceleration Channelsand combines them with a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision. Following the approach of Noctua’s A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 2000 to 1700rpm. Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing and a rich bundle of accessories, the NF-A12x25 is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.
Highly optimised P/Q curve for all applications
The NF-A12x25’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.
Noctua’s 120mm fans such as the NF-F12 and NF-S12A are renowned as being among the best on the market and have received more than 400 awards and recommendations from the international press. With its further improved efficiency and novel, state-of-the-art engineering, the NF-A12x25 represents another step up in performance and manufacturing.
Ultra-tight tip clearance
The NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.
Metal-reinforced motor hub
The centrepiece of the NF-A12x25’s motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination, both measures ensure ultimate precision and increased stability in the critical hub area.
Scope of delivery
Next-Gen Sterrox Material
The NF-A12x25’s impeller is made from Noctua’s novel Sterrox liquid-crystal polymer compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics: ideal for reducing resonance and vibration phenomena in advanced fan-blade designs.

I couldn't stand the AIO pump noise from the NZXT Kraken x62 on my Ryzen 2700x build. After listening to a couple of other systems with the EVGA CLC280, Corsair H115, and H150 I determined that my ears are just tuned to pick up water pump noise. So the next step was the best air cooling solution I could find: The Noctua NH-D15 SE-AM4. With my case the stock NF-a15 fans for that heatsink assembly wouldn't clear both the ram and the case side panel. Thanks to some reviews for this fan along with Noctua saying it was a compatible match, I decided to try these fans for the heatsink in order to keep the twin fan capability. I also opted to replace my (7) NF-A14 PWM case fans with (6) NF-A12X25 fans. I was intrigued by the development cycle and the promise of excellent low mid-range to high mid-range rpm pressure and flow rate.
These fans deliver in a way the fringes of my hopes dared to imagine possible but didn't actually expect to exist. With the NH-D15 SE-AM4 I obtain the same boost clocks with only a 2c penalty in Prime 95 small FFT or Folding@Home CPU work units vs. the NZXT Kraken x62 with push, pull or push/pull NF-A14 fans. Where the kraken required the fans spun up enough to be audible from 3 feet away and on par (by ear) with the AIO pump noise to achieve the reference level of cooling the NF-A12x25s lose 2c at 950rpm: they are not audible without my ear in direct contact with the case. Best of all, I am running the AMD Ryzen 2700x at 4.1ghz all core under Prime 95 or F@h CPU and hitting 66c worst case scenario and the computer is completely silent at the seating position 3 feet away. This is well within temperature guidelines from AMD, at a significant boost over advertised all core boost clocks that is sustainable indefinitely and while having a total CPU and SOC combined 130 watts of power used. The pure silence and the temps at full load wouldn't be possible any other way. I tried. The Sterrox polymer based NF-A12x25 is a triumph in design and execution whose value is priceless and performance is peerless.
If you are reading the other reviews confusing static pressure and airflow, let me help with a car analogy: static pressure is like torque, and airflow is like horsepower. These fans have great static pressure, allowing them to reliably pull air against things that make it harder like radiators, filters, and when close to the sides of the case. They are not made to move tons of air really fast. If you want that, then get a fan that's more airflow optimized. They do, however, move plenty enough air to do all the cooling I need. Mine are installed in a Ncase M1 behind a radiator and they're practically silent and cool very well. Definitely worth the price tag.
Generally speaking, if the fan has more blades closer together then is a static pressure fan and if it has less blades that are further apart then it's an airflow fan. You're welcome!
So I bought a D15 ignorantly, not knowing the front fan wouldn't clear my tall-as-my-forehead RAM, so for awhile I was only using only fan in the middle in push configuration. Meh, not so good. Then I see these fans in Computex vids and was struck by the design. Man these things look sweet. If they perform well, that'll be a bonus to me, and BOY does it perform well. It comes with all sorts of adapters, but my D15 had all the ones I needed anyhow. Slapped that bad boy on and dropped my load temps by 5C without adding any perceivable noise. N i c e. I'm looking forward to the new U12S with two of these bad boys on there. Three words, sign me up, dawg. Four words.
I had to use one on my D15s due to my ram height and smaller ATX case. But it makes it look good. Preformes really well. Great temps.
Purchased 6 of these and I’m very happy. Thank you Notuca
I was curious to see if this fan was as good as they claimed, so I bought one to test out on my NH-U14S cooler. It absolutely outperforms the included (and larger) NF-A15 PWM fan. Now don't get me wrong, that fan is a really good one as well, but it has nowhere near the amount of static pressure this NF-A12x25 offers. Typically the higher the static pressure, the better it performs in restricted spaces (like CPU coolers and radiators). I also replaced the standard four corner anti-vibration pads, and installed the included NA-AVG1 gasket (which is supposed to work better for dense fins) that is shown on page 1 of the user's manual.
I run this new fan at 1200 RPM (it can go up to 2000 RPM if you want it to), and I can't hear it at all, and it keeps my i7-6700k between 38c - 51c while I stress it by doing Folding@Home 24/7. With the NF-A15 PWM fan, my CPU temperature would climb to about 58c at times.

Der Hecklüfter in meinem Gehäuse war bisher ein (eh schon guter) Noiseblocker eloop, den man aber im Sommer oder bei starker Auslastung des Systems schon gut hören konnte wenn er aufdrehte.
Der Noctua ist hier DEUTLICH leiser und auch besser in der Kühlleistung, ich bin wirklich begeistert und beeindruckt. Über kurz oder lang werde ich deswegen wohl auch noch einige andere Lüfter gegen diesen austauschen.
Übertrieben fand ich allerdings die Verpackung, die extrem hochwertig ist (aufklappbar mit Klettverschluss, Prägedruck etc). Für den Einzelhandel als Verkaufsargument nachvollziehbar - aber wenn ich das Ding bei Amazon bestelle, kaufe ich nicht wegen der Verpackung und würde mir lieber einen günstigeren Preis wünschen. Obendrein ist es einfach unnötige Umweltverschmutzung, für einen banalen Lüfter so viel Verpackungsmaterial zu produzieren. Ein einfacher Pappkarton wäre mir und meinem Gewissen lieber gewesen.
1) EK Varder 120mm. Good static pressure. Quite noisy. Terrible quality control. (1 fan defective out of 7 ordered. Fans do not rotate on axis "level" - easily visible).
2) Noiseblocker eLoop 120mm. Fairly weak static pressure. Fairly quiet. Excellent quality. (Note you should only use these in "push" not "pull" against a radiator, because of the design).
3) Corsair ML140 140mm. Very good static pressure. Fairly quiet. Good quality. Overall a good product.
4) Noctua NF-A12x25. Excellent static pressure (better than the very good ML140). Excellent silence (quietest of all at same each rpm). Excellent quality. 7 fans ordered. None defective. Great build quality and consistency.
The only problem with the NF-A12x25 is the price. I can get 2 ML140 for the price of one of the Noctua fans. I wish Noctua would sell the NF-A12x25 at a cheaper price without the bundled accessories, most / all of which are pretty useless to me and immediately get thrown into a spares box.
Note on my system: Currently I have 4x NF-A12x25 against one 480mm radiator. 4x ML140 against a 560mm radiator and 3x NF-A12x25 used as case intake fans. I am an experienced custom PC modder / builder.
I can't wait for NF-A14 fans to get updated to Sterrox standards. When they get released (maybe 2019) I will retire the ML140.
After a couple of weeks of internal struggle I decided to put down £80 for a set of 3 fans and give them a go. Figured hey its amazon I can always send them back if they don't blow my socks off.
All I can say is if you like silence these are the one. I upgraded from 3 ML120 pros and I still can't find my socks 1 month on. The ML pros were only silent at about 800-900 rpm and anything above 1400 was pretty awful. With these you get the same noise levels of 900rpm ml pros at about 1300-1400 rpm. Even running them at max although audible is completely fine due to the tone and pitch of the hum they make.
If your running a water cooled build I highly recommend these for your radiators. Of all my recent upgrades (2080ti/8700k etc) this is the purchase I've been most impressed by. If noise level matters to you give them a go!
Diese hier drehen nur 1200rpm und halten meine CPU bei 30 Grad - und dabei sind die Lüfter wirklich nicht zu hören.
Im Performance Modus drehen sie bei 1800rpm und drücken die Temperatur der CPU auf 23 Grad!
Eine wirkliche Verbesserung!
Ich würde 5 Sterne für das Produkt geben, das technisch und qualitativ wirklich gigantisch gut ist. Die Optik lässt leider sehr zu wünschen übrig. Passt farblich in Badezimmer von 1960.
Einen Stern Abzug gibt es aber für die absolut übertriebene und Umwelt-unfreundliche Verpackung. Ich kaufe das Produkt auf Amazon nicht, weil es eine tolle Verpackung hat, sondern weil das Produkt gut ist. Das Produkt wäre preislich attraktiver und darüberhinaus auch umweltfreundlicher, wenn die Verpackung dezenter gestaltet wäre.
Sie landet ja ohnehin im Müll.... da hätte ich mir von den österreichischen Herstellern mehr Bewusstsein erhofft.
It's the only noctua fan I've ever had issues with, but a significant issue at that. Infact its the first fan I've had "burn out" on me.
UPDATE: The replacement I received is still going strong 2 years on, so definitely got a dud the first time around. This single fan manages to cool a system consisting of a GTX 1060 and i5 9400f w/ L9i cooler. This is in a Lian-Li TU100B, which is smaller than most shoeboxes, whilst also keeping the system extremely silent even under load.
This is with the noctua set as the intake, but I can imagine swapping it to an exhaust (only 1 fan mount in this case) would remove even more heat at the expense of more dust.
CPU averages 70c, GPU maxes at around 75c. Can't ask for any more than this. The previous S12B was good but a lot louder.
