Noctua NF-A4x10-24V-PWM 40x40x10mm 24V Fan

This fan Noctua NF-A4x10-24V-PWM is a small 40 x 40 x 10 mm model aimed at specific applications and compact systems where space is critical, but reliable cooling is sought. It operates at 24V, has a 4-pin connector, and supports PWM control for finer speed regulation. At a maximum of up to 5000 RPM, it remains relatively quiet with a noise level of 19.6 dBA. The typical Noctua brown color suggests a focus on function rather than RGB effects.

What you get is a high-quality fan with an SSO2 bearing designed for long life and stable operation under prolonged load. Maximum speeds of 4200-5000 RPM combined with an airflow of 8.9 m³/h and static pressure of 1.95 mmH2O make it suitable for tight openings, small cases, control panels, or embedded systems. Thanks to PWM, you can keep the speeds low and quiet at idle, and only increase them when temperatures require it. The low amperage of 0.045 A is a big plus for devices with limited power budgets. The package includes a NA-AC9 4-pin molex to 2-pin adaptor cable, making integration into more specialized systems easier.

• Compact size 40 x 40 x 10 mm, convenient for small cases, panel systems, and tight mounting spaces.
• Speed range 4200–5000 RPM, providing stable airflow for cooling closely placed components.
• Airflow 8.9 m³/h, sufficient for small volumes of air where continuous movement is important, not massive flow.
• Maximum static pressure 1.95 mmH2O, suitable for blowing through grilles, filters, or tight openings.
• Noise level of only 19.6 dBA, which is important if the fan operates in an office environment, next to you on the desk, or in a room where silence matters.
• SSO2 bearing, aimed at long and reliable operation under 24/7 load.
• 4-pin PWM connector plus NA-AC9 4-pin molex to 2-pin adaptor for easy connection in non-standard systems.
• Low power consumption of 0.045 A, convenient for devices with limited power lines.
• Long warranty of 72 months, which is a strong indicator of trust in the product's reliability.

Who is this fan suitable for? For small industrial computers, controllers, compact cases, network equipment, or any custom projects where you need a 24V fan with PWM control and high resource. It is not a suitable choice for standard ATX gaming cases – it is simply too small and with a specific voltage for typical PC configurations.

The combination of 24V power supply, SSO2 bearing, PWM control, and a long 72-month warranty makes Noctua NF-A4x10-24V-PWM a very stable solution for small but demanding systems where you cannot afford to compromise on reliability.
