Information

The Noctua NF-A4x10 FLX is a compact 40mm case fan designed for use in tight spaces where reliable airflow and quiet operation are essential. With its distinctive brown colour and slim 10mm profile, this fan fits seamlessly into small form factor systems, mini-ITX builds, and other space-constrained environments. It connects via a 3-Pin connector and operates at a maximum rotational speed of 4500 RPM, delivering an airflow of up to 5 CFM and a maximum air pressure of 1.78 mmH2O, all while drawing just 0.05A of current.

Quiet and Efficient Performance
Despite its small size, the NF-A4x10 FLX keeps noise to a minimum, reaching only 17.9 dB(A) at maximum speed. This makes it an excellent choice for users who prioritise a quiet working or gaming environment. The fan does not feature PWM support or LED illumination, keeping the focus firmly on clean, efficient airflow without unnecessary distractions.

Advanced Bearing Technology
At the core of the NF-A4x10 FLX is Noctua's Self-Stabilising Oil-pressure (SSO) bearing, a refined magnetic bearing design that uses the rear of the rotor hub to provide additional stabilisation. This technology contributes to smooth, consistent operation and long-term reliability. The fan comes supplied with mounting screws, making installation straightforward and hassle-free for a wide range of compatible cases and cooling setups.
