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.
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).
