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.

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

Il test è stato condotto con un microfono posto a 20 cm di distanza per capire come la nuova struttura influenzasse la rumorosità e sono rimasto veramente colpito da come queste nuove ventole riescano ad avere un flusso d’aria così elevato ed uniforme, ma allo stesso tempo una bassissima rumorosità che si aggira intorno al 25% in meno rispetto le ventole NF-F12 se portate a pari velocità.
Test verdict: "Noctua come al solito non ha deluso le aspettative su questi nuovi prodotti, ed è riuscita a migliorare le sue proposte più performanti, tramite la nuova serie NF-A12x25 con l’utilizzo del nuovo materiale a cristalli liquidi Sterrox® LCP, andando così ad aumentare le prestazioni mantenendo una bassissima rumorosità."

NA-SFMA1 Review

As you can see the results the Noctua NF-A12x25 comes out with slightly lower temperatures.
Test verdict: "The NA-SFMA1 is the perfect choice for those who want to equip their 120 mm Noctua fans with 280mm liquid cooled radiators. " (Ambrosidou Nat, XtremeSystems.org)

NA-SFMA1 Review

Az évek során megszokhattuk, hogy a Noctua kiváló minőségű hűtési megoldásokat dob piacra. Tőlük nem kell várnunk különféle RGB-s ventilátorokat, vagy méretes vízhűtéseket – bár utóbbi termékvonal a pletykák szerint hamarosan érkezni fog – , hanem inkább abban jeleskednek, amiben szerintünk a legjobbak, azaz a ventilátorok terén igyekeznek évről évre maradandót alkotni. A kiváló minőséget a több száz elnyert díj és a pozitív vásárlói visszajelzések is bizonyítják. Persze a minőséget (és természetesen a kutatási költséget) meg kell fizetni… Mai tesztünkben két új ventilátorral ismerkedhettek meg, valamint elhoztunk nektek egy érdekes kiegészítőt, mellyel a Noctua a vízhűtés szerelmesei számára kínál egyfajta alternatívát.
Test verdict: "Az NA-SFMA1 tökéletes választás azok számára, akik 120 mm-es Noctua ventilátorokkal akarják felvértezni 280 mm-es folyadékhűtéses radiátoraikat." (Kocsis Bence, Rendszerigény.hu)
