Fan Noctua 120mm NF-S12B-redux-700

This 120 mm fan Noctua NF-S12B redux-700 is aimed at people who value silence above all else. It operates at up to 700 RPM, making it a typical low-RPM option for quiet cases, home, and office configurations. Despite the low speeds, it maintains an airflow of 33.49 CFM, which is more than sufficient for a well-ventilated mid-tower. The noise level of just 6.8 dBA places it in the territory of “I hear the power supply more than the fan.”

What you get

With this model, Noctua focuses on a balance between airflow and maximum low noise, operating at 12 V with a consumption of only 0.6 W and current 0.05 A, which is almost negligible load for any system. The SSO bearing and declared MTBF of 150,000 hours mean you can leave it spinning 24/7 for years without worries. The 3-pin connector makes it easy to connect to almost any motherboard or fan hub, with the ability to control via voltage (voltage control). The standard dimensions of 120 x 120 x 25 mm ensure compatibility with most cases, and the gray color is a neutral choice for a build where you are not looking for RGB, but clean air and silence.

• Standard size 120 x 120 x 25 mm, suitable for most cases and positions for intake or exhaust.
• Maximum speed of 700 RPM for an extremely quiet operating mode focused on acoustic comfort.
• Airflow 33.49 CFM / 56.9 m³/h, sufficient to maintain stable circulation in a well-planned airflow.
• Noise level of only 6.8 dBA, making it almost inaudible in a real system.
• Reliable SSO bearing and MTBF 150,000 hours for long-term, continuous operation.
• Low consumption of 0.6 W at 12 V and 0.05 A, without significant load on the power supply or motherboard.
• 3-pin connector for wide compatibility and easy speed control via voltage.

Who it is suitable for

This fan is for you if you are aiming for a maximally quiet PC for office, media center, or gaming machine that you don’t want to hear at night. It is suitable for systems with moderate thermal loads, where airflow is well planned and high speeds are not required. It is not the optimal choice if you are cooling a heavily overclocked configuration or very hot components in a poorly ventilated case.

The combination of low speeds, almost silent operation, and long bearing life makes the Noctua NF-S12B redux-700 a very reasonable choice for quiet, reliable airflow without unnecessary effects and compromises in quality.
