Noctua NF-A14x25 G2 PWM Sx2-PP chromax. black
Noctua NF-A14x25 G2 PWM Sx2-PP chromax. black
The Noctua NF-A14×25 G2 PWM Sx2-PP PC fan set contains two 140mm fans designed for efficiently cooling computer cases and water-cooling radiators. This dual fan set, in the chromax.black edition, features an all-black design that elegantly blends into builds with a focus on a uniform aesthetic. As a quiet PC fan, it uses advanced aerodynamic elements and precise construction for high airflow with low noise levels. Each PWM fan in the set allows for automatic speed control via a 4-pin connector, ensuring optimal performance and quiet operation. This Noctua fan is built with an SSO2 bearing and Sterrox material, which reduces vibrations and ensures long-term blade stability even at high speeds.
Key features of the Noctua NF-A14×25 G2 PWM Sx2-PP PC fan, chromax.black
- Blades made from Sterrox LCP material to reduce resonance
- AAO frame includes integrated anti-vibration pads
- Tight clearance between blades and frame for effective pressure
- SSO2 bearing offers a mean time between failures of over 150000 hours
- Flow Acceleration Channels technology to reduce noise
- PWM speed control from 0 to 1500 RPM
Advanced aerodynamics of the Noctua NF-A14×25 G2 PWM Sx2-PP PC fan
The fan's design features an impeller with a Progressive Bend design, a Centrifugal Turbulator hub, and winglets on the blade tips. Combined with a very small clearance between the blades and the frame of just 0.7mm, this system increases pressure and airflow while maintaining a low noise level. The blades, made of Sterrox liquid-crystal polymer, reduce vibrations and deformations, ensuring stable and quiet operation.
Optimisation for quiet operation
Technologies like the Flow Acceleration Channels on the blades and the AAO (Advanced Acoustic Optimisation) frame with integrated anti-vibration pads effectively reduce noise emissions. Both the frame and the blades reduce unwanted turbulence, creating a smooth and quiet sound profile even at higher speeds. Automatic PWM control ensures smooth and quiet speed management.
Sx2-PP dual fan set
The Sx2-PP package includes two fans with slightly different rotation speeds. This difference effectively reduces unwanted harmonic phenomena and vibrations that can occur when using multiple identical fans next to each other. The configuration offers flexible use for a push-pull setup on coolers or for side-by-side placement on water-cooling radiators.
Reliability and construction of the Noctua PC fan
The fan uses a second-generation SSO2 bearing, which ensures a long lifespan exceeding 150000 hours. The metal bearing shell ensures high precision and rotor stability. It also includes advanced protection features against over-voltage and short circuits, ensuring safe operation.
