Noctua NF-A14 5V PWM Fan 140mm 5V, PWM, USB

This Noctua NF-A14 5V PWM is a 140 mm fan aimed at those who seek a quiet and controllable airflow in a case or on a radiator, but operates with 5V instead of the standard 12V. You get a combination of 300–1500 RPM, PWM control, and USB power, making it quite flexible for PC, NAS, media center, or even DIY solutions. With SSO2 bearing and a noise level of up to 24.6 dBA, the fan is oriented towards long life and low noise. The color scheme is typically “brown Noctua” with no RGB.

What you get

At speeds from 300 to 1500 RPM, you can set the fan from nearly silent mode to serious airflow according to the system's needs. The flow rate of 140.2 m³/h and static pressure of 2.08 mmH2O mean that the fan is not just for cases – it is fully adequate for dense radiators or filters where resistance needs to be “broken through.” The SSO2 bearing is designed for long and quiet operation, so you don’t have to think about replacement for years. The 4-pin PWM connector gives you precise control through the motherboard or controller, while the additional USB power adaptor cable opens the door for cooling external devices, routers, consoles, or laptop stands. The package also includes anti-vibration pads, an extension, and an OmniJoin adapter, making installation easier in more unconventional situations.

• Size 140 x 140 x 25 mm – standard 140 mm format, suitable for both cases and 140 mm radiators.
• Speed 300–1500 RPM – wide range allowing for both nearly silent operation and more aggressive cooling under load.
• Flow 140.2 m³/h – provides serious airflow for large cases or systems with more components that generate heat.
• Max. pressure 2.08 mmH2O – sufficient static pressure for radiators, dense filters, and narrow openings.
• Noise level 24.6 dBA – oriented towards quiet operation, especially if kept in the lower RPM range.
• SSO2 Bearing – bearing focused on long life and smooth rotation with minimal vibrations.
• Connectors 4-pin + USB – flexibility for installation in standard PC systems or for power/control via USB.
• Warranty 72 months – 6 years coverage showing confidence in the fan's durability.
• Included accessories – 30 cm extension, NA-AV1 anti-vibration mounts, USB power adaptor, OmniJoin adaptor set, and screws for easy and clean installation.

Who it is suitable for

This fan is a good choice if you are looking for a quality 5V solution for a case or radiator with PWM control and you value silence and reliability over RGB effects. It is suitable for silent or home server builds, HTPC, NAS, as well as for those who want to cool devices via USB. If you are chasing a full RGB show or need a standard 12V fan for a typical gaming configuration, this is not the most logical choice.

The combination of 5V PWM, high flow for the 140 mm format, quiet profile, and rich packaging with adapters and anti-vibration mounting makes this Noctua NF-A14 5V PWM a very flexible solution for slightly more specialized and well-thought-out configurations.
