Noctua fan NF-P14S REDUX-1500 PWM 140 mm grey, 12V PWM, 450–1500 RPM, 133.7 m³/h, 25.8 dB

The Noctua NF-P14s redux is a square-frame 140mm PWM fan derived from the long-established NF-P14 design. Offered in a streamlined redux edition, it provides core Noctua features — pressure-optimised nine-blade impeller, industry-grade SSO-Bearing, custom PWM IC with Smooth Commutation Drive (SCD), and stop-at-0% PWM functionality — in a more affordable package. The square 140mm frame uses standard 140mm mounting holes (124.5mm spacing), making the fan suitable for case, radiator and CPU cooler use where full coverage and strong pressure performance are required.

Advantages

The NF-P14s redux delivers proven quiet operation and reliable long-term performance thanks to its SSO-Bearing and over 150,000 hours MTBF rating. Its pressure-optimised nine-blade design and square frame provide improved airflow and static pressure for high-impedance applications such as radiators and dense heatsinks. The custom NE-FD1 PWM controller with SCD reduces PWM switching noise, and the fan supports automatic stop at 0% PWM for semi-passive idle operation.

How to use

Install the fan using the standard 140mm mounting holes (124.5 mm spacing) either in a case or on a compatible 140mm radiator. Connect the PWM cable to a motherboard or fan controller header to allow automatic speed control; setting the PWM duty cycle to 0% will stop the fan for silent idle operation if system temperatures permit. For radiator or CPU-cooler installations, ensure the airflow direction and orientation provide optimal cooling and clearance for surrounding components.

Recommendations

For reduced vibration and visual customization, consider using Noctua NA-SAVP1 anti-vibration pads available in multiple colors. Optional accessories such as Low-Noise Adaptors, anti-vibration mounts, y-cables and extension cables can be used to adjust speed, reduce noise or simplify cabling. Use the fan on radiators, dense heatsinks or cases with restrictive grills where high static pressure and PWM control are needed.
