The Noctua NF-P12 redux-1700 PWM is a 120mm high-performance cooling fan designed for computer chassis and CPU cooler applications. Its construction features a robust glass-fiber reinforced polyamide frame that ensures structural integrity and long-term durability. The fan utilizes an advanced Smooth Commutation Drive system that reduces torque variations and minimizes operational noise, resulting in a stable and quiet performance profile. The redux series represents Noctua’s commitment to delivering reliable cooling solutions at a more accessible price point, making it an attractive option for budget-conscious builders seeking proven technology. This model operates at a maximum speed of 1700 RPM, delivering an airflow of 80.2 CFM and static pressure of 1.68 mm H₂O.

The included PWM control allows the fan speed to be adjusted dynamically between 450 and 1700 RPM, enabling a balance between cooling capacity and acoustics. The nine precisely angled blades are optimized for efficient air movement while minimizing turbulence. The fourth pin (PWM) connector ensures compatibility with modern motherboards for automated speed regulation based on system temperature. The fan’s bearing system employs a reliable SSO (Self-Stabilizing Oil-pressure) bearing that provides longevity and consistent performance over extended use. The outer casing features a sleek grey finish that blends well with various system build aesthetics.

The fan’s edges include anti-vibration pads that reduce transmission of mechanical noise to the case. The overall build quality reflects Noctua’s engineering standards, with tight tolerances in the blade hub and frame to prevent imbalance. The fan is compatible with typical mounting configurations for 120mm fans, and the 4-pin connector is standard across most consumer PC components. The unit’s power consumption is rated at 1.2 watts, contributing to an energy-efficient cooling setup. In terms of thermal performance, the NF-P12 redux-1700 PWM is well-suited for use as a case intake or exhaust fan, as well as for CPU coolers that accommodate 120mm fans.

Its moderate static pressure makes it effective for pushing air through dense heatsink fins or radiator cores. The fan’s noise output is rated at 25.1 dB(A) at full speed, which is relatively quiet for its airflow capacity. When run at lower speeds via PWM, the acoustic footprint decreases significantly, making it suitable for silent system configurations. The redux series offers a compelling combination of performance and value, providing a cost-effective alternative without sacrificing core reliability. The pricing of this fan at $16.35 positions it as a budget-friendly choice within the premium Noctua lineup.

The 1700 RPM variant strikes a balance between airflow and noise, appealing to users who require moderate cooling without heavy acoustic impact. The fan includes a 4-pin Y-cable for connecting multiple units to a single header, and a set of mounting screws. It is backed by Noctua’s standard manufacturer warranty, reflecting confidence in the product’s durability. For those seeking a dependable, quiet, and affordable cooling fan for their PC, the NF-P12 redux-1700 PWM delivers consistent performance at a reasonable cost.
