The NA-SFMA1 is a set of two NA-FMA1 fan mounting adaptors that permit the installation of the NF-A12x25 and several other Noctua 120mm fans on 140mm watercooling radiators (or other screw-mount applications that are designed for 140mm fans, e.g. as a case fan). Thanks to the superior efficiency of the NF-A12x25 fan, the NA-SFMA1 thereby enables users to boost the performance of their 140mm radiators by replacing the stock fans with NF-A12x25s. In addition to the two adaptors, the NA-SFMA1 includes eight NA-AV4 anti-vibration mounts, which give the extra benefit of damping any minute vibrations that might otherwise be transferred to the radiator and on to the PC case.
Caution: the NA-SFMA1 has been specifically designed to ensure an optimal fit of the NF-A12x25 fan on watercooling radiators. It is also compatible with the NF-F12, NF-S12A and NF-P12 redux models as well as some 120mm fans from other manufacturers, but due to the special adaption to the NF-A12x25’s frame shape, not all 120mm fans fit. The NA-SFMA1 can be used for other screw-mount applications such as installing the NF-A12x25 in 140mm case fan placements, but may not work with 140mm applications that feature different methods of mounting (e.g. CPU coolers with custom fan clips).

Boosting 140mm radiator performance with the NF-A12x25

Boosting 140mm radiator performance with the NF-A12x25

Noctua’s novel NF-A12x25 120mm fan has been thoroughly optimised for superior performance on mid to high impedance applications such as watercooling radiators and effectively outperforms many 140mm fans. The NA-SFMA1 thus allows the performance of 140mm-based all-in-one (AIO) or custom (DIY) watercooling systems to be boosted by replacing the fans with NF-A12x25s.
Dual pack for two fans

Dual pack for two fans

The NA-SFMA1 set includes 2 NA-FMA1 adaptors and 8 NA-AV4 anti-vibration mounts for installing two fans, thereby enabling users to set up either a single 140mm radiator in a push/pull configuration or a dual 140mm (280mm) radiator with two NF-A12x25 fans.
Vibration-free fan mount

The included NA-AV4 anti-vibration mounts damp any minute vibrations that may otherwise be transferred to the radiator and on to the PC case, which makes the NA-SFMA1 a great choice not only for those seeking to boost the performance of their 140mm watercoolers but also for silent enthusiasts who aim to reduce vibrations and resonances.
Easy installation

Easy installation

Installing NF-A12x25 fans on 140mm radiators using the NA-FMA1 is child’s play: Pull the supplied anti-vibration mounts through the adaptor’s fan mounting holes, fix the adaptor to the radiator using the original screws, put the fan on the assembly and pull the tips of the anti-vibration mounts through its mounting holes – done!
6-year manufacturer’s warranty

6-year manufacturer’s warranty

The NA-FMA1 adaptors are made from the same high-grade, fibreglass reinforced PBT material that is used for most of Noctua’s fans, which makes it just as sturdy as a Noctua fan frame. Like all Noctua products, the entire NA-SFMA1 set comes with a full 6-year manufacturer’s warranty.

NA-SFMA1 Review

We have tested the Noctua NF-SFMA1 on the NZXT Kraken X62. NZXT has provided AER P 140mm fans with this cooler. The rated speed of the NZXT AER P 140 is 500 ~ 1800 +/- 300 RPM. Noise level rating is 21 – 38 dBA. Fan operates on 12V DC and draws 0.35A with an input power of 4.20W. These fans are PWM design with 4-pin PWM power connector. For comparison, we have tested the fans for which these brackets are designed in particular aka NF-A12x25. We have tested the PWM version of these fans. Their rated speed is 2000 +/- 10% RPM with sound level 22.6 dBA. Static pressure rating is 2.34 mmH2O. [...] The idle temps using the NZXT AER P were 1.99°C whereas the idle temps were 1.83°C with the Noctua NF-A12x25 PWM. This is a marginal difference but keep in mind these are 120mm Noctua fans vs NZXT 140mm fans and noise level difference is huge between both fans. Real comparison will come from the under load temps. Under load, the NZXT Kraken X62 was doing 38.83°C. With Noctua NF-A12x25 fans, the Kraken X62 was doing 38.5°C. Again we note a marginal difference but this is a significant boost in the performance from the 120mm fans using the 140mm bracket. Please, note that there is a 1 ~ 1.5m,m gap between the 120mm fans and the radiator when using this bracket. Against all odds, the fans have delivered a powerful punch.
Test verdict: "Against all odds the might and prime of the Noctua NF-A12x25 PWM outclass the competition in the noise-to-performance ratio. This goes to show that Noctua has brought out an accessory that would be a lethal cooling solution when coupled with their new generation NF-A12x25 (PWM/FLX) fans" (Nauman Siddique, EnosTech.com)

NA-SFMA1 Review

NF-A12x25 ventilatori donose neke nove tehnologije i materijale, a uz odlične radne karakteristike i zadovoljavajuće nisku radnu buku. Ovo je svakako najtiši ventilator na 2.000 okretaja koji smo čuli, a uz vrlo respektabilne brojke propusnosti i statičkog pritiska. Kao i uvijek, potrudili su se izbaciti nekoliko modela kako bi svatko pronašao opciju za sebe, a sve dolaze po istoj cijeni. Cijena kod Noctue nikada nije bila niska, a to je pogotovo tako kod premium proizvoda, pa A12x25 ventilatori koštaju preporučenih 29.99 €. Ako ih poželite ugraditi na 140-milimetarska mjesta, SFMA1 adapter s dva okvira će vas koštati 11.90 €. Za one koji ne žele izdvojiti za nove ventilatore, razveselit će činjenica kako se dobri stari P12 modeli u Redux seriji prodaju po prihvatljivih 13.90 € bez obzira na izvedbu.
Test verdict: "Neupitno je kako je Noctua oduvijek bila sinonim za kvalitetu, inovativnost i pouzdanost, a to i dalje potvrđuju novim serijama proizvoda koje izbacuju." (Krešimir Matanović, PC Ekspert)

NA-SFMA1 Review

Wszystkie pokazane dzisiaj konstrukcje są godne polecenia. Wersja Redux jest głośna, ale także dosyć wydajna. Brakuje jej jednak dodatków czy nakładek na boki – trzeba wtedy dokupić nakładki Chromax. Nowe śmigła NF-A12x25 fascynują jakością wykonania oraz kulturą pracy. Sprawdzą się one świetnie w obudowie, jak i na chłodnicy. Na podobnym poziomie głośności są wydajniejsze od konkurencji, więc wynik jest znakomity. Wszystkie przedstawione dzisiaj produkty polecam, bo naprawdę warto się nimi zainteresować.

NA-SFMA1 Review

El novedoso ventilador Noctua NF-A12x25 de 120mm ha sido minuciosamente optimizado para un rendimiento superior en aplicaciones de baja y media impedancia como los radiadores de refrigeración líquida, y puede superar eficazmente a muchos de los ventiladores de 140mm. Por lo tanto, el NA-SFMA1 permite aumentar el rendimiento de los sistemas de refrigeración líquida integrales (AIO) o personalizados (DIY) de 140mm si se sustituyen los ventiladores por el NF-A12x25. Las pruebas demostraron que la presión estática alcanzó unos impresionantes 2.34 mm-H2O, convirtiéndose en el compañero ideal de radiadores utilizados en refrigeración líquida de alto rendimiento. Es realmente impresionante oír al Noctua en funcionamiento. Sólo a pleno rendimiento de aprecia un leve siseo. El resto del tiempo, silencio. Los soportes anti-vibración NA-AV4 que se incluyen amortiguan la más mínima vibración que podría ser transmitida al radiador y a la caja del PC, por lo que el NA-SFMA1 se convierte en una excelente opción no solo para los que buscan aumentar el rendimiento de los dispositivos de refrigeración líquida de 140mm sino también para los usuarios que valoran el silencio y que desean reducir las vibraciones y resonancias. Noctua es la marca referencia en refrigeración por la excelsa calidad de sus productos y por la inigualable atención al cliente. Este kit de adaptadores es buena prueba de ello. ¡Excepcional!
Test verdict: "Con este producto Noctua da respuesta a los usuarios que desean potenciar su sistema de refrigeración líquida con los excepcionales NF-A12x15. Y lo hace con la maestría y excelsa calidad con la que nos tiene acostumbrados la marca. Noctua se ha ganado la confianza de los más exigentes por productos como este. Un conjunto der adaptadores bien diseñado que puede ser utilizado por el más novel de los usuarios. Una maravilla." (José Romero, RealHardTechX.com)

NA-SFMA1 Review

The company really pulled all the stops on paper and using the person it is simply impressive. Spinning the fan you don’t feel any of the stator “thumps” as it spins and the heavy steel core stores fan inertia offering an ultra smooth operation when the fan is changing speeds. The blade design is configured for high pressure applications and doesn’t have the typical cone shaped exit profile making it a great fit for radiator and case cooling.
Test verdict: "Noctua fans are extremely good at what they do and I have to say I am really impressed with the new NF-A12x25 design." (Dennis Garcia, HardwareAsylum.com)

NA-SFMA1 Review

So is the NA-SFMA1 worth it? Yes, absolutely yes, for me at least! Firstly, the radiator is now permanently attached to the case, and in a place where it gets fresh air from the environment instead of choked air passing through 2 fan spots and fighting the PSU for priority. Secondly, the radiator is able to be mounted above the pump now instead of below it – it only took one pump failure to learn that lesson and I’m happy having to worry about another. [...] The benchmark with the NF-A12x25 PWM fan and NA-SFMA1 adapter in the roof of the case speaks volumes when you consider that is the only change…
Test verdict: "Both the NA-SFMA1 140mm fan adapter and the NF-A12x25 PWM fan performed as well as I expected, not only boosting the existing capability of my GPU’s watercooler but finally allowing me to fit it in a sensible place so as to get the absolute best out of it."

NA-SFMA1 Review

La verdad es que poco más tenemos que decir al respecto de este sistema de adaptación de ventiladores. Es una solución inteligente para aquellos que ya disponen de ventiladores de la compañía y quieren montarlos en bloques de refrigeración liquida pensados para ventiladores de 140mm o para los chasis que tengan solo anclajes de 140mm. El NA-SFMA1 es un simple adaptador pero se ha pensado para ser resistente, contando con seis años de garantía e influir lo menos posible tanto en el rendimiento como como en la sonoridad gracias a los adaptadores de goma que absorben las vibraciones.
Test verdict: "Aquellos que ya tengan ventiladores Noctua de 120mm y adquieran chasis o bloques de refrigeración líquida que solo admitan ventiladores de 140mm, podrán usarlos gracias a estos nuevos adaptadores que incluyen anclajes de goma contra las vibraciones." (Roberto Solé, HardwareSfera.com)

NA-SFMA1 Review

I will repeat myself as Noctua products are simply amazing. Both presented fans so the NF-12x25 and NF-P12 perform well and are really quiet as Noctua declares. These fans have already received multiple prizes around the Internet so it won’t be strange to see one more from our redaction.
Test verdict: "If you are searching for the best fans on the market then Noctua is the top choice." (Bartosz Waluk, FunkyKit.com)

NA-SFMA1 Review

Как и всегда, наилучшие показатели температур, а значит и производительности, наблюдаются у вентиляторов с более высокой скоростью вращения. Первое место между собой делят Noctua NF-A12x25 PWM (2000 об/мин) и Noctua NF-P12 redux-1700 PWM (1700 об/мин). Тем не менее, именно NF-A12x25 лидирует в плане шума, отыгрывая у NF-P12 redux без малого 4 дБ (А). Да и субъективно, новый вентилятор Noctua не имеет паразитных призвуков и звук его работы не вызывает раздражения даже на максимальной скорости. В то же время стоковый вентилятор Zalman завывает на скорости 1900 об/мин, проигрывая один градус по температуре. При той же температуре и сниженной до 1700 об/ скорости NF-A12x25 выступает с ним на равных, но уже с вполне терпимым шумом на уровне 48 дБ (А). При дальнейшем понижении скорости в направлении 1200–1350 об/мин картина сохраняется, NF-A12x25 лидирует по низкому уровню шума, NF-P12 redux показывает тот же результат, но делает это заметно громче. Общая производительность вентиляторов заметно снижается на отметке в 900–1000 об/мин, и тут себя неожиданно хорошо по температуре показывает вентилятор Zalman, однако его крыльчатка работает слишком шумно, в то время как у Noctua эти режимы работы можно считать почти бесшумными.
Test verdict: "Вполне может претендовать на звание самого тихого 120-мм вентилятора в мире." (Vasilenko Andrey, Overclockers.com.ua)

NA-SFMA1 Review

High-End will gelernt sein: Der NF-A12x25 stellt einen Quantensprung im 120-mm-Segment dar, derartige Fortschritte sind im Kühlungsbereich aber extrem selten und verlangen viel Know-how. Viele Oberklasse-Lüfter haben ihr Niveau durch jahrelanges Feintuning erreicht – hier einfach mal was neues/anderes zu versuchen, führt selten zu einer PCGH-Kaufempfehlung.
Test verdict: "120-mm-Fan schlägt 140 mm. Die Spitze der Wertungstabelle ist eine Überraschung und zugleich ein alter Bekannter." (Torsten Vogel, PC Games Hardware 10/18)
