Noctua NF-A6x25 FLX 60 x 25 mm Case Fan, Brown

The Noctua NF-A6x25 FLX is a 60mm fan engineered for applications where space is limited, such as in small form factor (SFF) builds or for targeted component cooling. It is built upon Noctua's SSO2 bearing, a self-stabilizing oil-pressure design intended to provide high operational stability and long-term reliability. The fan's aerodynamic efficiency is enhanced by an Advanced Acoustic Optimisation (AAO) frame and proprietary Flow Acceleration Channels on the blades. These features work in tandem to direct airflow and reduce turbulence, which contributes to its low noise profile.

This FLX model operates on a 3-pin connector and provides three distinct speed settings through the use of included Low-Noise Adaptors. The fan's native speed is 3000 RPM, which can be reduced to 2400 RPM or 1600 RPM to balance cooling performance with acoustic output. At its maximum speed, it generates an airflow of 17.19 CFM and a static pressure of 0.61 mmH2O. The fan housing and impeller are constructed from PBT material, which offers a high degree of durability and dimensional stability over time.
