Noctua NF-A14 iPPC 24V 3000 SP IP67 PWM 140mm single-phase motor

This is a 140 mm industrial fan Noctua NF-A14 iPPC 24V 3000 SP IP67 PWM, aimed at more serious systems – from tightly packed cases to radiators in higher-demand environments. It operates at 24 V DC and reaches up to 3000 RPM, which means very serious airflow and static pressure. The color is entirely black, without RGB, making it more of a functional than a “show” solution. With SSO2 bearing and MTBF 150000 hours, it is designed for long, stable life.

What you get

With a range of 800–3000 RPM, you can set it for quieter operation or maximum cooling when everything heats up seriously. The fan generates up to 158.5 CFM airflow (269.3 m3/h) and 6.58 mmH2O static pressure – exactly what you need for dense radiators or cases with more restricted airflow. It is controlled via 4-pin PWM, so you can tie the RPM to the system temperature and not keep it running at maximum all the time. The consumption is 7.92 W at 0.33 A, which is normal for a 24 V fan of this class. The noise level at maximum RPM is 41.3 dBA – at 3000 RPM this is an expected compromise for such airflow.

• 140 x 140 x 25 mm format, which fits standard 140 mm positions for cases and radiators.
• Range of 800–3000 RPM, allowing you to choose between quieter operation and aggressive cooling.
• Powerful airflow of 158.5 CFM / 269.3 m3/h for effectively expelling warm air or strongly blowing on a radiator.
• High static pressure of 6.58 mmH2O, suitable for dense radiators and fronts with narrower openings.
• SSO2 Bearing bearing with MTBF 150000 hours, focused on reliability and long life during prolonged operation.
• 24 V DC power supply and 4-pin PWM connector for precise control of RPM according to load.
• Noise level up to 41.3 dBA at maximum RPM, fully justified for a fan with such airflow and pressure.
• Sleek black design without RGB, suitable for serious builds and environments where aesthetics are not a priority.
• Long 72 months warranty, which shows confidence in the durability of the fan.

Who it is suitable for

It is suitable if you are aiming for serious cooling – whether for a dense radiator, a more loaded system, or an environment where the machine runs for long periods under load. It is more suitable for 24 V configurations and projects where there is a need for a combination of high CFM and high static pressure. If you are looking for a super quiet 12 V fan for a casual gaming build with RGB, this is not exactly your type of fan.

The strongest aspect here is the combination of high RPM range, serious airflow, and pressure, along with long life and stable bearing. This is a fan that is designed first for performance and reliability, and then for everything else.
