The NA-SAV3 is a fan accessory set consisting of 16 NA-AV3 anti-vibration mounts for up to four fans. Replacing standard fan screws, the NA-AV3 mounts enable the convenient, quick and vibration-free installation of fans in standard mounting holes for case fans. Five defined, numbered pawls allow the NA-AV3 to work perfectly with both standard open corner fans (pawl 1) and 10, 14, 15, 20 or 25mm thick fans with closed corners (pawls 2 to 5). This makes the NA-AV3 ideal for slim fans where other anti-vibration mounts may not fit properly.
