Noctua NA-SAV4 mounting kit

The NA-SAV4 is a fan accessory set consisting of 16 NA-AV4 anti-vibration mounts for up to 4 fans. Replacing standard fan screws, the NA-AV4 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-AV4 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-AV4 ideal for slim fans where other anti-vibration mounts may not fit properly. With their flat case-side end, the NA-AV4s are flush with the case panel and thus provide for a clean exterior look.
