Product Overview
The Noctua NF-P12 redux-1700 PWM is a premium 120 mm case fan from Noctua’s redux series — a streamlined, performance-focused version of the classic NF-P12 fan that maintains the brand’s quality at a more accessible price. It’s designed for efficient airflow and pressure, making it suitable for case ventilation, CPU heatsinks, and water-cooling radiators.
Key Specifications
- Size: 120 × 120 × 25 mm — standard for most PC cases and coolers.
- Connector: 4-pin PWM for automatic speed control with compatible motherboards.
- Speed Range: ~450 RPM to 1700 RPM (max).
- Airflow: Up to 120.2 m³/h (≈ 70.7 CFM) at maximum speed.
- Static Pressure: ~2.83 mm H₂O — strong for forcing air through heatsinks or radiator fins.
- Noise Level: ~25.1 dB(A) at full speed — relatively quiet for high-performance fans.
- Bearing: SSO2 bearing for long life and stable operation (>150,000 h MTTF).
- Warranty: 6 years — typical for Noctua fans.
Design & Performance
Airflow & Cooling
The NF-P12 redux-1700 PWM delivers strong airflow and static pressure, making it versatile for both general case cooling and more demanding duties like pushing air through CPU coolers and radiators. Its nine-blade pressure-optimized design helps sustain airflow when facing resistance from heatsinks or filters.
PWM Speed Control
Because it uses a 4-pin PWM connector, this fan can automatically adjust its speed based on system temperatures when connected to a compatible motherboard header. This helps balance cooling performance and noise output without manual tuning.
Quiet Operation
Noctua’s Smooth Commutation Drive (SCD) and SSO2 bearing technologies reduce PWM clicking and mechanical noise, making this fan quieter than many generic alternatives even at higher RPMs.
Build Quality & Lifespan
Noctua fans are known for long life and reliability. The redux-1700 PWM model continues this tradition, with a high MTBF rating and robust materials that support extended operation in demanding environments.
Pros & Cons
Pros
✔ Balanced performance — strong airflow and static pressure make it suitable for case, heatsink, and radiator use.
✔ Quiet at medium speeds compared to many high-speed fans.
✔ PWM control allows automatic speed scaling for quieter everyday use and boosted cooling when needed.
✔ Reliable SSO2 bearing with long expected lifespan and minimal maintenance.
✔ Good ecosystem support — optional accessories (anti-vibration mounts, cables) are available for customization.
Cons
✘ Noise at full speed — at ~1700 RPM, the fan can produce noticeable noise relative to high-end silent models, especially under load. — industry and user reports note this behavior at higher RPMs.
✘ Redux aesthetics — grey color and simpler design may not match premium builds with black or RGB fans. — visual observation from redux series.
✘ Performance isn’t best-in-class compared with Noctua’s higher-end models like the NF-A12x25, which offer superior airflow/noise balance per watt. — general community comparisons
Who This Fan Is For
💻 PC builders seeking a reliable, performance-oriented 120 mm fan that can handle both intake/exhaust and heatsink/radiator duties.
🔇 Users balancing noise and performance — PWM control helps achieve quieter operation at lower temperatures.
🛠 DIY and enthusiast builders looking to replace stock fans with higher-quality airflow solutions without the premium price of flagship models.
It’s less ideal for those seeking absolute silence at all times or for builds prioritizing aesthetics like all-black or LED lighting, where chromax.black.swap or other styled fans might fit better. — visual preference observation.
Final Verdict
The Noctua NF-P12 redux-1700 PWM is a solid midrange 120 mm fan that brings trusted Noctua reliability with balanced cooling performance. Its strong airflow and static pressure, coupled with PWM speed control and long manufacturer warranty, make it a smart choice for system builders who want better cooling than basic case fans without spending on high-end premium models.
