Noctua NF-A14x25r G2 PWM chromax.black Fan 140mm

This Noctua NF-A14x25r G2 PWM chromax.black is a 140 mm case fan aimed at serious builds where you want a lot of airflow but without excessive noise. The black chromax design makes it discreet and easy to combine with any setup, even without RGB. With a range of 300–1500 RPM and airflow up to 91.58 CFM, this is a fan that can comfortably take on the role of a primary intake or exhaust. At the same time, the noise level of 24.8 dBA keeps it in the quiet class for the 140 mm format.

What you get

You get a 140 x 140 x 25 mm fan with SSO2 bearing, which is optimized for long life and stable operation – supported by 150000 hours MTBF. The maximum static pressure of 2.56 mmH2O is a good plus if you use denser filters on the case or have a more closed front – the fan won’t “struggle” immediately. The wide range of speeds 300–1500 RPM through 4-pin PWM gives you fine tuning: almost silent idle and serious airflow under load. With a consumption of only 2.28 W at 12 V and 0.19 A, the load on the motherboard is minimal, so you can easily connect several fans to one fan header via a hub (within reason). The package includes NA-AV2 anti-vibration mounts, screws, and NA-EC1 30 cm cable, so installation and cable management are covered without additional purchases.

• 140 mm format (140 x 140 x 25 mm) – a good balance between high airflow and lower noise compared to smaller fans.
• 300–1500 RPM with 4-pin PWM connector – full control through the motherboard for quiet operation under low load and serious airflow during gaming or rendering.
• Airflow up to 91.58 CFM / 155.6 m3/h – suitable for cases with more powerful GPU/CPU configurations, where stable expulsion of warm air is necessary.
• Static pressure 2.56 mmH2O – allows effective operation behind filters and denser grilles without drastically dropping airflow.
• Noise level 24.8 dBA – focus on silence, so it won’t annoy you during long sessions, even when the fan spins up.
• SSO2 Bearing and MTBF 150000 hours – long-life bearing, suitable for 24/7 machines, without worrying about replacement soon.
• Full black chromax design and no RGB – clean, minimalist look for builds without flashy lights or with already sufficient lighting.
• Included 4x NA-AV2 anti-vibration mounts, screws, and 30 cm extension – less vibration to the case and more flexible cabling right from the box.
• Consumption 2.28 W (12 V, 0.19 A) – gentle on fan headers and suitable for connection through controllers and hubs.
• Warranty 72 months – long-term coverage that logically goes with the high MTBF.

Who it is suitable for

It is suitable if you are building a quiet but powerful gaming or workstation build and want a reliable 140 mm fan for intake or exhaust. It is especially a good choice for cases with filters and more closed panels, where the combination of high CFM and decent pressure matters. If you are after a strong RGB show and lights from every angle, the lack of lighting may disappoint you.

The combination of high airflow, low noise, and very long life makes this fan a logical investment for a build that you won’t change soon. You simply install it, adjust the PWM curve, and forget it exists – which is the idea behind good cooling.
