Compact 60x25mm PWM case fan

The Noctua NF-A6x25 PWM is a premium quiet 60x60x25mm 12V fan with a 4-pin PWM connector and SSO2 bearing. It runs from 550 to 3000 RPM and produces up to 19.3 dB(A) at full speed. Flow Acceleration Channels and an Advanced Acoustic Optimisation frame improve airflow quality while keeping noise low. Supplied accessories include anti-vibration mounts, screws, a Low-Noise Adaptor, an extension cable and a y-cable for two fans on one header.

Ideal for tight spaces and noise-sensitive gear

This fan suits DVRs, NAS units, network switches, storage devices and 3D printers that use a 60x25mm mounting pattern and benefit from automatic speed control. The broad PWM range and Low-Noise Adaptor let the system balance cooling and silence. Buyers who need a different mounting hole spacing or a larger frame size should look elsewhere.

60x60x25mm mounting footprint

The single specification that decides fit is the 60x60x25mm frame with standard 60mm screw-hole spacing. If your device or case calls for that exact footprint and a 4-pin PWM header, this fan will install directly. Any other frame dimensions or connector type means this model will not fit.

Questions about this item

How long is the SSO2 bearing rated to last before replacement?

The manufacturer specifies an MTTF of more than 150000 hours for the SSO2 bearing, indicating a very long service life under normal conditions.

What is the maximum airflow the fan can sustain at full 3000 RPM speed?

At the maximum rotational speed of 3000 RPM the fan delivers 292 m³/h of airflow, which is the highest sustained output it can provide.

How loud does the fan get when running continuously at its top PWM speed?

At the full 3000 RPM PWM speed the acoustical noise is 19.3 dB(A), a level Noctua describes as premium quiet performance.
