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. 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 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 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!
