Noctua NF-A14x25r G2 PWM 140mm fan

This is a 140 mm PWM fan Noctua NF-A14x25r G2 – a classic for quiet and efficient airflow in the case. It is positioned more in the high-end segment for case cooling, with an emphasis on silence and stability during long 24/7 operation. It spins from 300 to 1500 RPM, providing a serious airflow of up to 91.59 CFM while keeping noise to 24.8 dBA. Add to that the SSO2 Bearing and MTBF 150000 hours, and you get a fan for long service without unnecessary noise.

What you get: 140 x 140 x 25 mm format, which fits in most mid and full tower cases and is optimal for front, top, or rear placement. The range of 300 – 1500 RPM gives you a lot of flexibility – you can keep it at nearly silent 300–500 RPM for idle and ramp it up when the CPU and GPU heat up. With up to 2.56 mmH2O static pressure, the fan performs well even through denser mesh panels or finer dust filters. The 4-pin PWM connector allows you to set an aggressive or quiet curve in BIOS or through software, without unnecessary max spinning. And with a real consumption of up to 2.28 W at 12 V and 0.19 A, you won’t overload the fan headers on the motherboard.

• Size 140 x 140 x 25 mm – standard 140 mm format, suitable for most modern cases with larger intake and exhaust positions.
• RPM 300 – 1500 – wide range for super quiet operation at idle and high flow during gaming or rendering.
• Airflow 91.59 CFM – sufficient for serious airflow throughout the case, even in warmer configurations.
• Max. pressure 2.56 mmH2O – better airflow through radiators, filters, and dense panels.
• Noise level 24.8 dBA – balanced profile for cooling without annoying whistling sound.
• SSO2 Bearing and MTBF 150000 hours – high-quality bearing for long life and stable operation under 24/7 load.
• 4-pin PWM, 12 V, 0.19 A / 2.28 W – full control through the motherboard and low consumption, without risk for the fan connectors.
• 9 blades and classic brown color – optimized blade design and typical Noctua look, without RGB distractions.

Who it is suitable for: if you are looking for a quiet yet effective system – gaming, workstation, or just a stable daily PC – this fan fits excellently for case airflow. It is also suitable for users who want their machine to run long and often under load, without frequently changing fans. If you are looking for an RGB show and addressable lights, this is not your model – the focus here is solely on cooling and reliability.

The combination of a wide RPM range, high CFM, and low noise, plus a long warranty of 72 months, makes Noctua NF-A14x25r G2 PWM a very sensible choice if you want to finish with the topic of “case fans” for years to come.
