Noctua NF-A12x25 PWM Fan - 120mm [NF-A12x25 PWM]

The Noctua NF-A12x25 PWM is Noctua's latest flagship fan. Noctua worked on the development for 4.5 years. Thanks to innovative aerodynamic design measures, it achieves impressive silent cooling performance. This is made possible, among other things, by the narrow impeller gap of just 0.5 mm. Equipped with a 4-pin PWM connector , the fan speed can be regulated and is between 450 and 2,000 revolutions per minute. However, the fan runs pleasantly quietly at a maximum of 22.6 dB(A) and still offers an air flow rate of up to 102.1 m³/h and a static pressure of 2.34 mmH2O.

The features of the Noctua NF-A12x25 PWM fan at a glance:
- SSO2 bearings for high performance, quiet operation and long durability
- 2,000 revolutions per minute at 102.1 m³/h & 22.6 db(A)
- PWM control between 450 and 2,000 RPM
- Integrated anti-vibration pads to lower the volume
- Convincing quality with a 6-year manufacturer's guarantee

The Noctua NF-A12x25 PWM in detail
Overall, the new top model from Noctua achieves impressive values. The 120 mm fan rotates at 450 to 2,000 revolutions per minute and generates an air flow rate of up to 102.1 m³/h. Nevertheless, the fan reaches an extremely low volume of only a maximum of 22.6 db(A). Ideal for all silent fans and overclockers!

Made from the new Sterrox LCP material combined with innovative aerodynamic optimization, the NF-A12x25 PWM is absolutely convincing. One of the special features is the narrow impeller gap of only 0.5 mm. This allows extremely efficient operation with improved dynamic pressure, which is particularly noticeable on coolers and radiators. To make this possible, the rotor is made of Noctua's Sterrox liquid crystal polymer (LCP), which is particularly strong and has low thermal expansion.

In addition, the hub area of the fan is metal reinforced to improve stability. So that silent fans are also enthusiastic despite the impressive performance of the NF-A12x25 PWM , the fan knows how to convince with various technologies. Flow Acceleration Channels accelerate the air in the outer areas, improving efficiency and reducing noise. The airflow is through the stepped intake areaand improves the microstructure inside the frame.

With the Smooth Commutation Drive 2, the NF-A12x25 PWM has the latest drive system from Noctua , which reduces torque fluctuations and ensures surprisingly smooth running. In order to further optimize the already very good fan, Noctua has integrated the already proven SSO2 bearing technology, which achieves excellent long-term stability.

Vibrations can be reduced with anti-vibration pads and Noctua supplies anti-vibration sealing lips for mounting on radiators . Another accessory is aLow-Noise Adapter (LNA) included, which reduces the maximum revolutions per minute to 1,700. If two fans are to be operated on one connection, this is also possible thanks to a 4-pin Y cable . A practical 30cm cable extension for large housings completes the accessories.
