Noctua NF-A14 ULN fan - 140mm
- Fan diameter: 140
Noctua is one of the well-known names in the silent cooling sector, with the Austrian manufacturer's CPU coolers in particular enjoying an excellent reputation. They combine outstanding build quality with high cooling performance and minimal noise generation. Noctua's in-house developed fans, which are also available separately for use as case or CPU fans, are largely responsible for this.
The NF-A14 is a quiet 140mm premium fan with a square AAO (Advanced Acoustic Optimisation) frame. Its square shape and 140 mm mounting holes make it an excellent choice for use on water-cooling radiators or as a case fan. Thanks to advanced aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 achieves even better silent cooling performance than the multiple award-winning NF-P14.
The ULN version, with its super-slow speed options (800/650 rpm), enables virtually silent operation and is therefore perfect for ultra-low-noise applications and particularly noise-sensitive users. Its superb smoothness of operation, the SSO2 reference-class bearing, and Noctua's proven premium quality make the NF-A14 ULN a top solution for the highest demands.
Noctua's NF-P14 has developed into a standard solution for PC enthusiasts who need 140 mm fans in premium quality. Through extensive aerodynamic optimisations, the NF-A14 achieves even higher static pressure compared to its renowned predecessor, as well as a further improved ratio of airflow performance to noise generation.
With its square frame and 140 mounting holes (124.5 mm hole spacing), the NF-A14 is an ideal premium upgrade for standard 140 mm case fans. At the same time, it is perfectly suited for use on 140 mm water-cooling radiators, where the square shape guarantees full coverage of the cooling fins and therefore the best pressure performance.
The impeller of the NF-A14 is equipped on the intake side with so-called Flow Acceleration Channels. By accelerating the airflow in the critical outer regions of the fan blades, intake-side flow separation is reduced, resulting in higher efficiency and lower turbulence-induced noise emissions.
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as a stepped inlet area (Stepped Inlet Design) and microstructures on the inner surface (Inner Surface Microstructures), which enable even better performance/noise efficiency.
The anti-vibration pads made from extra-soft silicone reduce the transmission of even the slightest vibrations and are also compatible with all standard screws as well as standard mounting systems or fan clips used on CPU coolers.
Despite its further improved performance, the NF-A14 ULN's power consumption is only 0,48W. This means the fan is not only environmentally friendly, but also helps you reduce your electricity bill!
Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A14 features an MTBF specification of more than 150,000 hours and comes with a full 6-year manufacturer's warranty.
