Noctua NF-A14x25 G2 LS-PWM Premium Fan 140x25mm -tuuletin

Succeeding the award-winning nf-a14 and building on the technological innovations of the ground-breaking nf-a12x25, the nf-a14x25 g2 is noctua’s next-generation square-frame 140mm flagship model: made from sterrox® lcp, its highly optimised progressive-bend impeller with winglets, flow acceleration channels and centrifugal turbulator hub combined with a tip-clearance of only 0.7mm allow the nf-a14x25 g2 to further improve its predecessor’s renowned quiet cooling performance. Like the nf-a14 and nf-a12x25, it is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, static pressure demanding scenarios such as on heatsinks and water cooling radiators. For application-specific optimisation, the nf-a14x25 g2 comes with an na-avg2-lr anti-vibration gasket pre-installed to create a tighter seal on radiators. Additionally, its aao (advanced acoustic optimisation) frame can be combined with the optional na-is1-14 inlet spacer, which can help to achieve superior suction acoustics and flow rates in challenging intake configurations. The 4-pin ls-pwm version is a low-speed, pwm-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and pwm based speed control. Its super-low-loss etaperf™ motor with smooth commutation drive 2 technology combines unprecedented energy efficiency with a superb running smoothness that is guaranteed to satisfy even the most noise-sensitive users. Topped off with noctua’s reference-class sso2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the nf-a14x25 g2 is a premium-quality product through and through. Its superior performance, comprehensive feature set, cutting-edge construction and state-of-the-art materials set a new standard within noctua’s portfolio and make it an elite choice for the most discerning demands.next-generation performancenoctua’s nf-a14 is renowned as being among the best 140mm fans on the market and has received more than 100 awards and recommendations from the international press. With its further improved efficiency and novel, state-of-the-art engineering, the nf-a14x25 g2 represents another step up in performance and manufacturing.highly optimised p/q curve for all applicationsthe nf-a14x25 g2’s sophisticated aerodynamic design allows for a pressure to airflow (p/q) curve that is extremely strong in the critical mid-section. This means that the nf-a14x25 g2 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.excellent on-application acousticswhile many fans produce unpleasant, high-pitched noises when installed in typical applications such as on heatsinks or radiators, the nf-a14x25 g2 has been carefully fine-tuned for optimal on-application acoustics. It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (spl) when working against back pressure.progressive-bend impellerthe nf-a14x25 g2 features a unique progressive bend impeller with flow acceleration channels and winglets. Its nine blades are swept backwards close to the hub and progressively bent forward further out. Working in tandem with the centrifugal turbulator hub, this design not only helps to push more air towards the outer blade areas where efficiency is higher but also assures maximum lift and near uniform loading across the entire blade span.centrifugal turbulator hubacting as a turbulator, the new centrifugal turbulator hub design improves flow attachment in the hub region. At the same time, it’s centrifugal driving motion pushes air outwards from the hub area where efficiency is low due to the slow rotational speed towards the outer, high-efficiency zones of the blades, thereby increasing overall efficiency by optimising fluid distribution across the impeller area.flow acceleration channelsthe nf-a14x25 g2 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.wingletswinglets can help to reduce tip vortices that are caused by the pressure differential between the suction and the pressure side of fan blades but bear the risk of reducing efficiency due to extra fluid displacement in high velocity regions. The nf-a14x25 g2’s small winglets have been carefully fine-tuned to provide consistent efficiency gains working in tandem with its progressive-bend blade geometry, flow acceleration channels and aao frame.ultra-tight tip clearancethe nf-a14x25 g2 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.7mm. This highly ambitious design sets a new benchmark for 140mm fans and helps the nf-a14x25 g2 to work more efficiently against back pressure, such as o
