Noctua NF-S12A PWM — Beige/Brown

107.5 m³/h17.8 dB(A)AAO frame6-Year Warranty

The Noctua NF-S12A PWM (part number NF-S12A PWM) is a 120 mm 4-pin PWM case fan that moves 107.5 m³/h (63.3 CFM) at 1200 RPM and only 17.8 dB(A), optimised for quiet case ventilation in desktops and workstations. It combines an AAO frame with integrated anti-vibration pads, an SSO2 bearing rated above 150,000 hours MTTF, a Low-Noise Adaptor and a 6-year warranty.

Typically in stock with fast delivery across Cyprus.

Compatibility note: Standard 120 × 120 × 25 mm fan with a 4-pin PWM connector — works with any motherboard fan header; the included Low-Noise Adaptor caps the maximum speed, and the 4-pin Y-cable lets two fans share one header. Fits 120 mm case and radiator mounts. No RGB lighting.
Best For
✓ Quiet case intake and exhaust
✓ Silent office and studio PCs
✓ Home servers and NAS builds
✓ Low-restriction mesh cases
✓ Replacing noisy stock fans
✓ 24/7 systems

Key Features

 
AAO Frame
Advanced Acoustic Optimisation frame with a stepped inlet, inner-surface microstructures and integrated anti-vibration pads for quieter operation.
 
S-Series Blades
Refined blades with Anti-Stall Knobs improve airflow-to-noise efficiency, moving 107.5 m³/h at just 17.8 dB(A).
 
SSO2 Bearing
Noctua’s self-stabilising oil-pressure bearing is rated for more than 150,000 hours MTTF.
 
Low-Noise Adaptor
The included L.N.A. lowers top speed to 900 RPM and noise to 10.7 dB(A) for near-silent builds.

Frequently Asked Questions

Does the Noctua NF-S12A PWM work with my motherboard?
Yes. The 4-pin PWM connector works with any motherboard fan header; the included Y-cable lets two fans share one header and the Low-Noise Adaptor caps speed at 900 RPM.
Is the NF-S12A PWM suitable for radiators?
It is designed for case ventilation. With 1.19 mmH2O static pressure it is fine for open intakes and exhausts, but for radiators or dense heatsinks the NF-F12 PWM or NF-A12x25 PWM is the better choice.
What is the difference between the NF-S12A PWM and the NF-F12 PWM?
The NF-S12A PWM is airflow-optimised (107.5 m³/h at 17.8 dB(A)) for case cooling, while the NF-F12 PWM is pressure-optimised (2.61 mmH2O) for radiators and heatsinks.
What do I need to know before buying the NF-S12A PWM?
It is a single 120 mm fan in Noctua’s classic beige/brown colour, with no RGB. It is ideal where silence matters most; for restrictive setups choose a pressure-optimised model. Warranty is 6 years.
Singular Expert Insight
The NF-S12A PWM is one of the quietest ways to ventilate a case: 17.8 dB(A) at full speed, and 10.7 dB(A) with the L.N.A. For radiators pick the NF-F12 PWM instead. Compare it with other case fans in our range.

Buyer's Guide

Buy it if
You want a very quiet 120 mm case fan with 107.5 m³/h airflow, a long-life SSO2 bearing and a 6-year warranty.
Skip it if
You need high static pressure for a radiator (see NF-F12 PWM) or want RGB lighting or a black finish.
Also consider
Noctua NF-F12 PWM for radiators, Noctua NF-A12x25 PWM, or be quiet! Silent Wings 4 120mm PWM.
