Premium 140mm quiet fan

The NF-A14 PWM is a 140mm square-frame case fan designed for quiet cooling in PC cases and on water-cooling radiators. It uses a 4-pin PWM connector for automatic speed control and runs on 12V power. The SSO2 bearing and Flow Acceleration Channels support low-noise operation at high airflow.

Upgrade from standard case fans

This fan replaces typical 140mm case fans when lower noise and better radiator compatibility are needed. The square frame with 124.5mm mounting holes fits 140mm radiators and standard case mounts. The included Low-Noise Adaptor reduces the maximum speed from 1500 RPM to 1200 RPM for quieter builds. Builders who need higher static pressure at speeds above 1500 RPM should look elsewhere.

Airflow and headroom

At full speed the fan delivers 82.52 CFM at 24.6 dB(A). With the Low-Noise Adaptor it provides 67.98 CFM at 19.2 dB(A). The PWM range spans 300 to 1500 RPM, giving headroom for demanding thermal loads while staying quiet at idle. It handles case intake, exhaust and radiator duty, but is not suited for applications requiring airflow beyond 82.52 CFM.

Questions about this item

What are the mounting hole dimensions for this 140 mm fan?

The square frame uses 140 mm mounting holes with 124.5 mm centre-to-centre spacing, matching standard 140 mm case and radiator mounts.

How do I connect the 4-pin PWM connector and what is the common mistake?

Plug the 4-pin PWM connector into a motherboard PWM header; the common mistake is leaving the Low-Noise Adaptor in-line when full 1500 RPM performance is needed.

What is the rated lifespan and does the bearing need lubrication?

The SSO2 bearing is rated for over 150000 hours MTTF and is self-lubricating, so no maintenance or re-lubrication is required.
