Noctua NF-A14 PWM fan - 140mm [NF-A14 PWM]

They combine excellent workmanship with high cooling performance and minimal noise. For this purpose, the self-developed fan from Noctua are largely responsible, which are also available separately to serve as a CPU or case fans.

The NF-A14 is a silent 140mm premium fan with square AAO (Advanced Acoustic Optimisation) framework. Its square shape and 140mm mounting holes make it an excellent choice for use on water-cooling radiators or fan housing. Through advanced aerodynamic design measures, such as Flow Acceleration Channels of NF-A14 reaches to the award-winning NF-P14 further improved quiet cooling performance.

The PWM version features Noctua's NE-FD1 IC designtem specifically for fully automatic speed control and comes with a low-noise adapter, which allows a reduction of the maximum speed of 1,500 to 1,200 r / min. His performance-oriented maximum speed and the comprehensive options for speed control make the NF-A14 PWM to a point solution for users who want to achieve a perfect balance between excellent cooling power and superb running smoothness - no matter whether on water-cooling radiators, heat sinks or ventilation of the case!

Noctua NF-P14 has become a standard solution for PC enthusiasts who need premium quality 140mm fan. Through extensive aerodynamic optimizations of NF-A14 achieves compared to its renowned predecessor, still higher static pressure and an improved relationship again of capacity and noise.

With its square frame and 140mm mounting holes (124.5 mm hole spacing) of the NF-A14 is an ideal premium upgrade for standard 140mm case fan. At the same time it is perfectly suited for use on 140mm water cooling radiators where the square shape ensures full coverage of the cooling fins, thus best printing performance.

The impeller suction side of the NF-A14 is equipped with so-called flow acceleration channel. By speeding up the air flow in critical regions of the fan blades outer suction vortex shedding can be reduced, which leads to a higher efficiency and a lower vortex induced noise emission.

Noctua AAO (Advandced Acoustic Optimisation) frames have built-in vibration buffer, a stepped inlet area (Stepped Inlet Design) and a microstructure inside (Inner Surface Microstructures), which allow an even better performance / noise efficiency.

Made from extra soft silicone anti-vibration pads to reduce the transfer minimal vibration and are also compatible with all standard screws and standard mounting systems or used CPU coolers fan brackets.

To guarantee the highest level of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A14 accesses a back CNC milled bearing shell made of brass. The NF-A14 is equipped with the further optimized second generation of Noctua grade SSO-bearing system. SSO2 at the back magnet is closer to the fan axis, causing an even better stability, which leads to further improved accuracy and durability.

Noctua fans are renowned for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A14 an MTBF specification of over 150,000 hours and comes with full 6 years manufacturer's warranty.
