Ventoinha Noctua NF P12 redux-1700 PWM, 120 mm, 12 V, 1700 RPM, 4-Pin PWM, 120,2 m³/h, 25,1 dB

The Noctua NF P12 redux-1700 PWM is a 120 mm case and component cooling fan engineered for balanced airflow and pressure. Operating between 450 and 1700 RPM, it delivers up to 120.2 m³/h of airflow and a maximum static pressure of 2.83 mmH2O. The fan uses a hydraulic bearing designed to reduce noise and increase operational lifetime. Its neutral grey finish suits a range of system builds where effective cooling and understated aesthetics are required.

Advantages

The fan combines a wide rotational speed range with controlled airflow and elevated static pressure, making it suitable for installations that need airflow through obstacles such as radiators or dense drive cages. The hydraulic bearing supports quieter operation compared with basic sleeve bearings and contributes to durable performance under continuous use. PWM control enables automatic speed adjustment according to system cooling demands, improving efficiency and reducing unnecessary noise.

Suitable for

• Case ventilation for mid-tower and full-tower PC systems
• Cooling of air-cooled components such as VRM or chipset areas
• Use on CPU coolers or radiators that accept 120 mm fans where moderate static pressure is beneficial
• Replacement or upgrade of existing 120 mm case fans to improve airflow or reduce noise

How to use

Install the Noctua NF P12 redux-1700 PWM in a compatible 120 mm mounting location using the standard fan screws or anti-vibration mounts. Connect the PWM cable to a motherboard fan header that supports PWM control to allow automatic speed regulation. Position the fan so airflow direction aligns with your system's ventilation strategy — intake at front/bottom, exhaust at rear/top, or on a radiator with the correct orientation for push or pull configurations. Secure cabling to avoid interference with other components or fan blades.

Recommendations

For optimal results, use PWM control via the motherboard or fan controller to let the fan adapt to temperature changes. When mounting on radiators, ensure a uniform sealing and minimal gap between fan and radiator fins to maintain static pressure efficiency. Periodic dust cleaning will preserve airflow performance and bearing longevity.
