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.Features:Vibration-free installation for lower noise emissionFans installed with standard fan screws can transmit minute vibrations to the PC case, which can lead to annoying resonance noises. Switching standard fan screws for NA-AV4 mounts can drastically reduce these structure-borne noises by effectively decoupling the fan from the PC case.Extra soft and highly tear-proofThe use of premium-grade silicone makes the NA-AV4 mounts both extra soft and highly tear-proof, allowing them to combine efficient decoupling with excellent longevity and ease of use.Flat case-side end for a clean lookWhile double-sided anti-vibration mounts like the NA-AV2 or NA-AV3 are convenient to install in space-restricted environments, some users prefer the clean appearance of single-sided designs. Therefore, the NA-AV4 mounts are flush with the case panel and thus look tidier from the exterior.5 defined pawls5 defined pawlsThanks to its five defined, numbered pawls, the NA-AV4 mounts are convenient to install even with 10, 14, 15 or 20mm deep fans (e.g. NF-A4x10, NF-A9x14, NF-A6x15, NF-A4x20) or 25mm fans with closed corners.Compatible with all Noctua fans and many third-party fansThe NA-AV4 mounts are ideal for the vibration-free installation of all current Noctua fans (including redux and industrialPPC models) as well as many third-party fans.Specification:- Colour: brown- Fan compatibility: all Noctua fans, many third-party fansContents:- 16x NA-AV4 anti-vibration mounts- Warranty 6 years
