Noctua 80mm 5V Fan, PWM, USB - NF-A8-5V-PWM

This Noctua NF-A8-5V-PWM fan is an 80 mm case cooler aimed at people who want reliable and quiet cooling at 5 V power supply. It operates with a wide range of speeds – from 450 to 2200 RPM, giving you flexibility between absolute silence and more serious airflow. At maximum speeds, it reaches up to 32.67 CFM (55.5 m3/h) and static pressure of 2.37 mmH2O, which is completely adequate for small cases, network devices, or other compact systems. Add in a 72-month warranty and an MTBF of 150,000 hours, and you get a fan that you can practically forget exists – it just works.

What you get

In practice, you get an 80 x 80 x 25 mm fan optimized for 5 V systems, which you can control precisely via a 4-pin PWM connector. This means you can keep it at around 450 RPM for nearly silent operation, and when needed, ramp it up to 2200 RPM for maximum airflow. The noise level at this is only 17.7 dBA, making it a very suitable choice for systems that need to remain quiet – media servers, HTPCs, routers, small cases under the desk. The SSO2 bearing ensures long life and stability in the long term, especially with 24/7 operation. With a USB power cable and OmniJoin kit, you can easily integrate it into devices without a standard fan connector, or even use it as a separate cooler powered directly from USB.

• A fan with a standard size of 80 mm and a thickness of 25 mm, suitable for compact cases and devices with limited space.
• A wide range of speeds from 450 to 2200 RPM, allowing you to balance between low noise and higher airflow as needed.
• Airflow up to 32.67 CFM (55.5 m3/h) and maximum static pressure 2.37 mmH2O, sufficient for effectively dissipating warm air from small systems.
• Very low noise level of only 17.7 dBA, making it suitable for quiet operation in offices, living rooms, and bedrooms.
• Works at 5 V with 4 pin PWM and USB connectors, providing flexibility for installation in PCs, network devices, DIY projects, or external solutions.
• SSO2 bearing and declared MTBF of 150,000 hours, plus 72 months warranty, which is a strong plus for long-term reliability.
• In the package, you get a 30cm extension cable, NA-AV1 anti-vibration mounts, USB power cable, OmniJoin kit, and screws for easier and cleaner installation.

Who is this suitable for?

It is suitable if you are building a compact or quiet system, have a device that operates at 5 V, or want a controllable PWM fan that can also run via USB. It’s a good choice for media centers, mini PCs, routers, NAS boxes, and any hardware where space is tight and silence is important. It won’t be optimal if you are looking for an RGB show effect or massive cooling for a large, heavily heating system.

The combination of 5 V power supply, PWM control, USB option, and very long life makes this Noctua NF-A8-5V-PWM a very flexible and practical fan for situations where standard 12 V PC fans are simply not convenient.
