The Noctua NF-A14x25 G2 PWM chromax.black is a premium 140mm case fan designed for enthusiasts who demand both high performance and a sleek all-black aesthetic. Built from a combination of ABS, PBT, silicone, and rubber materials, this fan delivers a refined look that integrates seamlessly into modern PC builds. Operating on 12V with a 4-pin PWM connector, it offers precise speed control and reaches a maximum rotational speed of 1500 RPM, all while keeping noise levels at a measured 24.8 dBA.
Advanced Bearing Technology
At the heart of the NF-A14x25 G2 PWM chromax.black is Noctua's Self-Stabilising Oil-pressure (SSO2) bearing. This bearing design uses a magnetic stabilisation system to keep the rear of the rotor axle in precise alignment, resulting in exceptionally smooth and consistent operation over time. The SSO2 bearing contributes to the fan's long-term reliability and whisper-quiet performance, making it a strong choice for systems where longevity and low noise are priorities.
High-Performance Airflow and Static Pressure
Featuring a 9-blade design, the NF-A14x25 G2 PWM chromax.black delivers a maximum airflow of 91.58 CFM and a maximum static pressure of 2.56 mmH2O, with a total airflow rating of 155.6 m3/h. These figures make it equally capable as a case ventilation fan or as a radiator-mounted fan. It is compatible with temperatures ranging from -10°C to 60°C and comes supplied with mounting screws for straightforward installation.
