With the introduction of the new Noctua NF-A14x25 G2, Noctua presents a next generation of fans that impress above all with their advanced technology and high efficiency. These 140 mm fans are based on the proven NF-A12x25 models and feature numerous innovations that result in a significantly improved combination of performance and quietness. Whether for gamers, IT professionals or PC enthusiasts – the NF-A14x25 G2 sets new standards in terms of cooling and noise minimization.
Important features at a glance:
- Advanced impeller technology: Sterrox LCP with winglets and flow acceleration channels
- Extremely small impeller gap: Only 0.7 mm for higher efficiency
- Anti-vibration sealing lip: Better sealing for radiators
- SupraTorque™ function: Additional speed reserves at high dynamic pressure
Technological innovations in detail
The NF-A14x25 G2 relies on the latest fan technology from Noctua, which is based on years of development work. The heart of the fan is the progressive bend impeller, which is made from the extremely stable material Sterrox LCP. This design allows high dimensional stability and reduces deformation at high speeds, which increases efficiency. The flow acceleration channels ensure that the air flows are accelerated in a targeted manner, which increases cooling performance and reduces noise at the same time.
The impeller gap of just 0.7 mm is particularly noteworthy. A narrower gap between the rotating fan blades and the frame ensures less air loss, making the fan even more efficient. This fine-tuning offers a clear advantage over conventional fans, as the combination of performance and quiet running is achieved in a new dimension.
In addition, the NF-A14x25 G2 is equipped with an anti-vibration sealing lip, which was specially developed for use on radiators. This lip ensures optimum sealing and prevents vibrations from being transferred from the fan to the radiator. This is particularly advantageous in pressure-oriented scenarios, such as water cooling systems, where high performance requirements are placed on the fans.
SupraTorque™ function and extended speed options
Another highlight of the NF-A14x25 G2 is the new SupraTorque™ motor. This offers the option of calling up additional speed reserves in the event of high dynamic pressure. In situations where the fan encounters resistance – for example with a severely restricted air supply in narrow housings or on dense radiators – the motor can still maintain a constant speed. This enables the fan to deliver high performance even under extreme conditions.
The NF-A14x25 G2 is available in different versions to meet individual requirements: the standard PWM version reaches a maximum speed of 1500 rpm, while the ultra-quiet LS PWM version is throttled down to 800 rpm. There is also the Sx2-PP set, which contains two fans whose speeds are slightly offset to avoid acoustic interference during parallel operation.
Versatile application options and accessories
The NF-A14x25 G2 is a true all-rounder and can achieve excellent results in airflow applications, such as case ventilation, as well as in pressure-oriented scenarios, such as on radiators and CPU coolers. The AAO (Advanced Acoustic Optimization) frame can be combined with an optional NA-IS1-14 spacer, which contributes to better acoustics and higher airflow performance in difficult intake configurations.
The fan also features Noctua’s tried-and-tested SSO2 bearing, which stands for quiet running and a long service life. With a 6-year manufacturer’s warranty, Noctua also offers comprehensive protection, making the NF-A14x25 G2 a long-term investment.
Conclusion
The Noctua NF-A14x25 G2 is the new frontrunner in the 140 mm fan category and offers an impressive combination of cooling performance, efficiency and quietness. Thanks to the numerous technological innovations such as the narrow impeller gap, the SupraTorque motor and the anti-vibration sealing lip, Noctua is once again setting new standards in the field of fan technology. With different versions and an extensive accessory package, the NF-A14x25 G2 is a versatile solution for anyone who wants to get the most out of their cooling system.
