Vibration from fan is not a nightmare anymore. XIGMATEK invents and patents an Anti-vibration rubber, AFK-R5381, to provide a fan faster for securing a heatsink and cooling fan. AFK-R5381 prevents vibration of the heatsink cooling fan during is operation and avoids noise problem and it can support for fan depth up to 38mm (ex: 9238 & 12038 fan). Moreover, AFK-R5381 presents a faster and easier way for securing a heatsink cooling fan to a heatsink, which fits to different types of heatsink cooling fans.
