Noctua NF-A14x25 G2 PWM Sx2 CHBK chromax.black Case Fan 140 mm 2-pack Black

The Noctua NF-A14x25 G2 PWM Sx2 CHBK is a set of two 140mm fans engineered for high-efficiency airflow in PC cases and on liquid cooling radiators. Each fan incorporates an aerodynamic blade design, featuring a Progressive Bend impeller and minimal tip clearance to enhance performance. This construction is particularly effective in high-impedance applications that require strong static pressure, such as with dense heatsinks. The all-black chromax.black color scheme provides a uniform aesthetic suitable for a wide range of system builds.

These fans support 4-pin PWM control, enabling automatic speed adjustments based on system temperatures for a balance between cooling and noise. The Sx2 configuration uses a slight speed offset between the two fans to mitigate potential harmonic interference when they are installed in tandem. Each fan is equipped with Noctua's SSO2 bearing for long-term operational stability and reliability. Included anti-vibration mounts and gaskets further help to reduce the transfer of mechanical noise to the PC chassis during operation.
