Efficient case ventilation fan

The Noctua NF-S12B redux-1200 is a 120mm case fan built for low-impedance cooling tasks. It uses the proven NF-S12B blade design to move high volumes of air through open mesh or unrestricted chassis layouts. A 12V 3-pin connector allows speed control via motherboard headers or optional voltage reducers. The streamlined redux package keeps the essential fan and four mounting screws.

Builders prioritising quiet airflow over static

This model suits systems where case ventilation is the main goal and airflow resistance is low. It is not for radiators, dense dust filters or tight heatsinks that demand higher static pressure. Buyers who need PWM speed control or a 4-pin connector should look elsewhere. The grey colour scheme may not match all interior themes.

SSO bearing rated beyond 150000 hours

The SSO bearing and MTBF rating above 150000 hours indicate long-term reliability under continuous operation. This single figure helps decide whether the fan meets a build's expected service life. No other specifications from the data sheet outweigh this durability metric for the intended use case.

Questions about this item

Does the box include mounting hardware or do I need to buy screws separately?

The package contains the fan and four fan screws for standard case mounting.

How does the 1200 RPM version differ from other speed options in the redux line?

This 1200 RPM model runs at 18.1 dB(A) and moves 100,6 m³/h, aimed at a balance of airflow and quietness.

What does the 18.1 dB(A) figure mean once the fan is installed in a case?

At 1200 RPM the fan produces 18.1 dB(A), which is very quiet for typical case ventilation with low airflow resistance.
