You get strong airflow when needed and quiet operation at idle. The grey unit measures 140x140x25 mm and weighs 5.29 ounces. It is built for chassis ventilation or radiator mounting.
What stands out
- 140x140x25 mm frame size fits standard 140mm mounts
- Maximum speed of 1500 RPM for strong airflow
- Noise level capped at 25.8 dB(A) for quiet operation
- 4-pin PWM connector enables motherboard speed control
Who it fits
Good fit for
This fan suits builders who want reliable cooling without high noise. The 1500 RPM speed provides excellent static pressure for radiators. You will appreciate the PWM control for adjusting speeds based on system load. The low noise rating makes it ideal for quiet PC cases. If you need a standard 140mm fan with proven reliability, this model fits your chassis ventilation needs well.
Who should skip it
You should look elsewhere if you need silent operation below 25 dB. The 1500 RPM version is louder than the NF-A14 series. If you prefer the classic brown aesthetic, the grey color may not match your build. You might also skip this if you need a 120mm fan, as this is strictly a 140mm unit. The redux line offers fewer premium features than the premium series.
Verdict: The Noctua NF-P14s redux-1500 PWM delivers solid 140mm performance with predictable noise levels. It is a practical choice for standard chassis ventilation.
Noctua 140mm Redux Fan Specs
Fan Size: 140mm
This dimension refers to the width and height of the fan frame. A 140mm fan moves more air than a 120mm unit at the same speed. You get better airflow for lower noise levels. This size fits standard 140mm mounting holes in most PC cases. Check your case specifications to ensure the mount matches before buying.
Max Fan Speed: 1500 RPM
This value indicates the highest rotational speed the fan reaches. At 1500 RPM, the fan generates strong airflow for active cooling. It is suitable for radiators or high-airflow chassis needs. You can lower this speed via motherboard settings for quieter operation. Compare this to slower fans if silence is your priority.
Noise Level: 25.8 dB(A)
This measurement shows the sound output at maximum speed. 25.8 dB(A) is considered quiet for a 140mm fan running at high performance. It is barely audible in a typical room. This level suits users who want cooling power without significant background noise. It is quieter than many 120mm fans running at similar speeds.
Connector Type: 4-pin PWM
This connector allows your motherboard to control fan speed automatically. Pulse Width Modulation provides precise adjustments based on system temperature. You get strong airflow when the system is hot and near-silent operation when idle. This is the standard for modern PC cases. Ensure your motherboard has a 4-pin fan header for full functionality.
Design and Build Quality
According to the listing, the Noctua NF-P14s redux-1500 PWM measures 140x140x25 mm. The frame is square, which allows it to fit standard 140mm mounting holes in chassis panels or water cooling radiators. You can use it for case ventilation or as a radiator fan. The unit weighs 5.29 ounces. This mass helps reduce resonance during operation. The color is grey, matching the neutral aesthetic of most modern PC cases.
The fan uses a 4-pin PWM connector. This interface lets your motherboard adjust the speed automatically. You get powerful airflow when the system is under load. The unit runs at a maximum of 1500 RPM. At lower speeds, it remains virtually silent. The listing notes an MTTF of over 150,000 hours. This figure suggests the motor is built for long-term reliability in continuous operation.
Noctua includes optional accessories like anti-vibration mounts and S-ATA adaptors. These items help you manage cable routing and reduce vibration noise. The streamlined redux edition focuses on proven quality without extra frills. You get a functional, spec-driven cooling solution. It suits builders who want reliable airflow without complex features. The design prioritizes function over flash. You can trust the listed dimensions and connector type for your build planning.
Setup And Daily Use
Installation begins with mounting the fan using the included anti-vibration mounts. These pads reduce vibration transfer to your chassis or radiator. The square frame aligns with standard 140mm screw holes. You can secure it to case panels or water cooling radiators. The 4-pin PWM connector plugs directly into your motherboard. This interface allows automatic speed control. The fan adjusts its RPM based on system temperature. At idle, it remains nearly silent. Under load, it ramps up to 1500 RPM. This provides strong airflow when you need it. The 25.8 dB(A) noise level is the maximum output. You will not hear a loud whine during normal operation. The grey color blends with most modern PC builds. Weighing 5.29 ounces, the unit is light but sturdy. The 12V power requirement is standard for desktop components. You can use S-ATA adaptors or y-splitters if you need more fans from one header. These accessories offer flexible wiring options. The >150,000 hour MTTF suggests long-term reliability. You do not need to replace it frequently. The streamlined redux edition focuses on core function. It lacks the premium packaging of higher-end models. However, the performance remains consistent. You get proven Noctua quality without extra features. The fan works well for case ventilation. It also suits water cooling radiators. The balance of airflow and quietness makes it practical. You can install it in intakes or exhausts. The 140mm size moves more air than smaller fans. This helps keep your system cool. Setup is straightforward for anyone familiar with PC building.
Before You Buy This Fan
Before you buy, verify your case has 140mm mounting holes. This fan requires that specific frame size. Check your motherboard headers for a 4-pin PWM connection. This connector enables automatic speed control based on system temperature. You get strong airflow when needed and quiet operation at idle. The included anti-vibration mounts help reduce noise transfer. You may also need S-ATA adaptors or y-splitters if you lack enough fan headers. These accessories are often available separately. Keep the fan blades clean to maintain performance. Dust accumulation can restrict airflow over time. This model sits alongside other high-end options in the 1 products listed here. It offers a proven design with excellent static pressure. The 1500 RPM speed provides a solid balance for most builds. Consider your cooling needs before finalizing your purchase. Ensure the 25.8 dB(A) noise level fits your environment.
Check before you buy
- Verify your case supports 140mm mounting holes
- Check for available 4-pin PWM motherboard headers
- Confirm you have enough fan connectors or splitters
- Ensure the 25.8 dB(A) noise level suits your needs
