Fan Noctua 120mm NF-S12B redux 1200 PWM

This is the 120 mm fan Noctua NF-S12B redux 1200 PWM – a classic case fan for reliable and quiet air cooling. The model is oriented towards balanced airflow and low noise, without unnecessary effects and RGB. With speeds from 400 – 1200 RPM and a noise level of only 18.1 dBA, it is a good choice for quiet cases and office/home configurations. The gray design and 4-pin PWM connector make it easy to fit and control in any build.

What you get

NF-S12B redux 1200 PWM is aimed at optimal airflow – up to 59.21 CFM / 100.6 m3/h, which is more than enough for good ventilation of mid-tower cases. The range from 400 to 1200 RPM gives you flexibility – from nearly silent idle mode to stable airflow under load. The SSO Bearing is designed for long life and minimal vibrations, which is felt during long-term operation 24/7. The maximum static pressure of 1.31 mmH2O makes it more suitable for free airflow through meshes and filters than for dense radiators. The low consumption of only 0.9 W at 0.075 A on 12 V minimally loads the power supply and fan headers on the motherboard.

• Size 120 x 120 x 25 mm – standard format for most cases, easy installation in the front, back, or top.
• Speed 400 – 1200 RPM – wide range for quiet operation at low load and stronger airflow when needed.
• Flow 59.21 CFM / 100.6 m3/h – sufficient airflow for effective cooling of components in a well-ventilated case.
• Max. pressure 1.31 mmH2O – optimized for case ventilation through mesh panels and dust filters.
• Noise level 18.1 dBA – very quiet profile, suitable for silent builds or workstations in quiet rooms.
• SSO Bearing – high-quality bearing for long life, stable operation, and less vibration.
• 4-pin PWM connector and 40 cm cable – precise control of speeds from the motherboard and sufficient length for convenient cable management.
• Consumption 0.9 W @ 12 V, 0.075 A – minimal load on fan headers and power supply.
• No RGB, gray color – clean, unobtrusive look for a compact, functional build.
• Warranty 72 months – long-term peace of mind for the reliability of the fan.

Who it is suitable for

This fan is suitable if you are aiming for a quiet, reliable, and purely functional system – gaming, work, or home PC, without a focus on RGB aesthetics. It is ideal for front intake or rear exhaust in cases with good perforation and mesh panels. If you are looking for high static pressure for dense radiators or aggressive high-RPM airflow, you may not have enough “push” here.

The combination of low noise, stable airflow, and quality SSO bearing, plus the long 72-month warranty, makes the Noctua NF-S12B redux 1200 PWM a very reasonable choice for quiet and reliable airflow in the case.
