Ventilador para caja de ordenador Noctua NF-A6X25 FLX 60 mm, 12 V, 1600–3000 RPM, 29,2 m³/h, 0,61 mmH2O, rodamiento SSO2

The Noctua NF-A6x25 FLX is a 60x25mm premium-quality quiet fan engineered for high airflow and low noise. It features Flow Acceleration Channels, an AAO frame, Smooth Commutation Drive technology and SSO2 bearings for stable, long-lasting operation. The fan comes with modular cabling, Low-Noise and Ultra-Low-Noise adapters for three speed settings, and a 6-year manufacturer warranty.

Advantages

The fan’s Flow Acceleration Channels and reduced motor hub increase blade efficiency and reduce vortex noise. The AAO frame integrates anti-vibration pads, Stepped Inlet Design and Inner Surface Microstructures to improve flow attachment, lower tonal intake noise and suppress boundary-layer effects. Smooth Commutation Drive 2 and the SSO2 bearing ensure very smooth rotation, low switching noise and enhanced durability. Modular sleeved cabling, an extension cable and a 3:4 pin adapter provide flexible installation options.

How to use

Mount the fan using standard screws or clips compatible with heatsinks, ensuring the integrated anti-vibration pads face the mounting surface if required. Choose one of the supplied adapters to set the desired speed (3000, 2400 or 1600 RPM) depending on the balance between airflow and noise. Use the 30 cm extension and the 3:4 pin adapter when the fan needs to be connected directly to the power supply or placed farther from the motherboard header. Ensure airflow direction matches your cooling layout.

Recommendations

For best results, use the NF-A6x25 FLX in constrained spaces where high static pressure and low noise are required, such as compact cases or dense heatsink assemblies. Regularly check mounting and cable connections and follow Noctua’s maintenance guidance to preserve long-term performance.
