The Noctua NF-A14x25r 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 with a combination of ABS, PBT, silicone, and rubber materials, this fan integrates seamlessly into any modern build. It connects via a 4-pin PWM connector, allowing for precise speed control, and operates at a maximum rotational speed of 1500 RPM within a temperature range of -10 to 60 degrees Celsius.
Advanced Airflow and Pressure Performance
The NF-A14x25r G2 delivers impressive airflow figures, reaching up to 155.6 m3/h with a maximum standardised airflow of 91.58 CFM. With a maximum static pressure of 2.56 mmH2O and nine aerodynamically optimised fan blades, this fan moves air efficiently across a wide range of cooling applications. Despite its strong performance output, noise levels remain controlled at 24.8 dBA at full speed, striking a solid balance between airflow and acoustic comfort.
SSO2 Bearing Technology
At the heart of the NF-A14x25r G2 is Noctua's second-generation Self-Stabilising Oil-pressure (SSO2) bearing. This bearing design uses a magnetic stabilisation system to keep the fan axis precisely centred, reducing vibration and ensuring smooth, consistent operation over extended periods. The fan operates at 12V with a maximum voltage threshold below 13.2V, and comes supplied with mounting screws included in the package, making installation straightforward and convenient.
