Noctua NF-P14s redux-900 Fan

The Noctua NF-P14s redux-900 is a 140 mm square-frame case and radiator fan that combines Noctua's proven NF-P14 design with a cost-effective redux package. This 900 RPM model targets ultra-low-noise applications while retaining the brand's industry-grade SSO bearing, an MTBF of over 150,000 hours and a full 6-year manufacturer's warranty. The square 140 mm frame with standard 124.5 mm mounting spacing makes it suitable as a replacement for common 140 mm case fans and for 140 mm water-cooling radiators where full coverage and pressure performance are required.

Advantages

The NF-P14s redux-900 delivers quiet operation through its pressure-optimized nine-blade impeller, Vortex-Control Notches that reduce tonal noise, and Smooth Commutation Drive 2 for minimized switching noises and torque variations. Its SSO-bearing technology provides long-term stability and low noise over extended runtimes. The redux edition offers this proven performance in a streamlined, attractively priced package and is compatible with a range of optional Noctua accessories like anti-vibration mounts and Low-Noise-Adaptors.

Suitable for

• Case cooling for mid-tower and full-tower PC cases with 140 mm mounts
• 140 mm water-cooling radiators requiring full-frame coverage and higher pressure
• Ultra-low-noise desktop systems and noise-sensitive environments

How to use

Mount the NF-P14s redux-900 using standard 140 mm screw points (124.5 mm spacing) to the case or radiator bracket. Connect the fan to a 3-pin motherboard header or to a compatible power source; if necessary use Noctua adapters (e.g., Low-Noise-Adaptor or 3:4 pin adapter) to tailor speed and noise. Ensure correct airflow orientation for intake or exhaust by checking the arrow indicators on the frame. Tighten screws evenly and, if desired, fit anti-vibration mounts to reduce transmitted vibrations.

Recommendations

For best results in noise-sensitive builds, use the 900 RPM NF-P14s redux-900 on radiators or case positions where low RPM high-pressure performance is needed. Combine with anti-vibration mounts and, if additional speed control is required, use Noctua Low-Noise-Adaptors or motherboard fan control to balance cooling and acoustics.
