Fan Noctua 140mm NF-A14 ULN

The fan Noctua NF-A14 ULN is a 140 mm case cooler aimed at quiet and well-thought-out configurations – from home PCs to work machines where noise is critical. With very low RPMs of 650 – 800 RPM and a noise level of just 11.9 dBA, this is a fan that is practically inaudible in a normal environment. The size 140 x 140 x 25 mm gives you a good balance between airflow and low RPMs, and the SSO2 Bearing is designed for long and reliable life. Combined with a 3-pin connector and included accessories, installation is easy and flexible.

What you get is a case fan focused on silence without completely sacrificing airflow. With a flow rate of up to 46.97 CFM / 79.8 m3/h, NF-A14 ULN is a good option for quiet airflow configurations – for example, for front intake or quiet exhaust at the rear panel. Its low consumption of just 0.48 W at 0.04 A on 12 V means minimal load on the motherboard and power supply. The SSO2 Bearing and declared MTBF 150000 hours are a strong plus if you are building a system for long-term 24/7 operation. With the included anti-vibration mounts, extension cable, and adapter to 4-pin Molex, you can easily integrate it into older cases or more unconventional builds.

• 140 mm size (140 x 140 x 25 mm) provides good airflow at lower RPMs compared to smaller fans.
• RPM 650 – 800 for extremely quiet cooling, suitable for silent or media PC configurations.
• Airflow 46.97 CFM / 79.8 m3/h, sufficient for stable airflow in a well-ventilated case.
• Noise level 11.9 dBA, making it almost inaudible in a normal working environment.
• SSO2 Bearing bearing for long life and reliable operation with an MTBF of 150000 hours.
• 3-pin connector, compatible with standard fan headers on motherboards, plus 3:4-Pin adapter for direct connection to power supply.
• 4 anti-vibration mounts and 30 cm extension, which facilitate quiet installation and reaching more distant fan headers.
• Consumption of only 0.48 W at 0.04 A and 12 V, minimizing the load on the power supply and motherboard.
• 72 months warranty, ensuring long-term operation and peace of mind.

Who is this fan suitable for? For anyone looking for a maximally quiet system – office machines, home theater PC, music or studio PC, as well as for people who prioritize acoustics over aggressive airflow. It is not the best choice if you plan a heavily overclocked high-TDP build with limited airflow, where higher RPMs and more aggressive airflow are needed.

In summary, Noctua NF-A14 ULN impresses with the combination of very low RPMs, ridiculously low noise, and long life, backed by a 72 months warranty. If silence is a priority for you and you want to maintain stable airflow, this is a very sensible addition to your case.
