NOCTUA NF-A14-ULN Silent ümbris 140mm Fan
Succeeding the awardwinning NFP14 Noctuas NFP14 fan has become a defaultchoice among PC enthusiasts looking for a premium quality quiet 140mm fan. Thanks to its thoroughgoing aerodynamic optimisations the NFA14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor. Square 140mm frame The NFA14s square 140mm frame with 140mm mounting holes 124.5mm spacing makes it a premium grade replacement for common 140mm case fans and perfect for use on 140mm water cooling radiators where its square shape will ensure full coverage and best pressure performance. button Flow Acceleration Channels The NFA14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. button AAO Frame Noctuas AAO Advanced Acoustic Optimisation frames feature integrated antivibration pads as well as Noctuas proprietary Stepped Inlet Design and Inner Surface Microstructures both of which further refine the fans performance/noise efficiency. button Stepped Inlet Design Noctuas Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow which reduces tonal intake noise improves flow attachment and increases suction capacity especially in space restricted environments. button Inner Surface Microstructures With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures flow separation from the suction side of the blades is significantly suppressed which results in reduced blade passing noise and improved airflow and pressure efficiency. button Integrated AntiVibration Pads Integrated AntiVibration Pads made from extrasoft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. SSO2 Bearing The NFA14 features the further optimised second generation of Noctuas renowned timetested SSO bearing. With SSO2 the rear magnet is placed closer to the axis to provide even better stabilisation precision and durability. button Metal bearing shell In order to guarantee the highest possible degree of manufacturing precision minimum tolerance and excellent longterm stability the NFA14 sports a CNC milled bearing shell made entirely from brass. button Smooth Commutation Drive 2 The latest version of Noctuas advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NFA14 remarkably quiet even at very close distance. button 2 speed settings for maximum quietness Providing 800 and 650 rpm speed settings via the supplied adaptor the ULN UltraLowNoise version is tailor made for serious silent enthusiasts who demand superslow running speeds and utmost quietness of operation. Extensive cabling options The fans short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply. UltraLow Power Consumption Despite of its further improved performance the NFA14 ULN consumes only 0.48W of power. This doesnt only make it ecofriendly but also helps to cut down the electricity bill! 6 years manufacturers warranty Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans the NFA14 features an MTBF of more than 150.000 hours rating and comes with a full 6 years manufacturers warranty.
