The NA-SAV2 is a fan accessory set consisting of twenty NA-AV2 Anti-Vibration Mounts for up to five fans. Replacing standard fan screws, the NA-AV2 mounts allow for a convenient, quick and vibration-free installation of fans in standard case fan mounting holes. The double-side design makes the NA-AV2 easier to work with in space restricted environments and thanks to the use of premium grade rubber, these mounts are extra soft and highly tear-proof at the same time. Switching standard fan screws for NA-AV2 mounts can drastically reduce structure-borne noises and makes this set a perfect complement for Noctua’s redux and industrialPPC fans!
