Arctic Server Fan 120x120x38 Dual Ball - S12038-4K - ACFAN00296A

This Arctic server fan with a size of 120 x 120 x 38 mm is designed for serious and reliable cooling in cases and server chassis, where airflow and pressure are critical. It operates in a wide range from 600 to 4000 RPM, giving you flexibility – from quieter mode to maximum performance. With an airflow of 106 CFM and maximum pressure of 11.45 mmH2O, it can push through dense radiators, filters, and tight grilles without issue. Completely black, without RGB, the focus here is entirely on functionality and durability, reinforced by Dual Ball Bearing bearings and a long warranty of 72 months.

What you get

This fan is designed for environments where machines run 24/7 and you cannot compromise on cooling. The range of 600-4000 RPM allows you to use it both as a quieter case fan and as an aggressive server fan when the thermal load spikes. 106 CFM airflow and 11.45 mmH2O pressure are particularly useful in deep rack cases with many components and limited airflow. Dual Ball Bearing with Brass Housing ensures stable operation for years, including when mounted in any orientation, and the operating temperature range of -10°C to 70°C makes it suitable for harsher conditions. Protections such as Reverse Polarity Protection, Over Voltage Protection, and Over Current Protection protect both the fan and the power circuit from connection errors or anomalies.

• Standard size 120 mm and thickness 38 mm, providing a more serious airflow compared to typical 25 mm fans.
• Wide range of 600-4000 RPM, allowing you to balance between quieter operation and maximum cooling according to system needs.
• Airflow of 106 CFM, suitable for server cases and dense configurations where you need quick removal of hot air.
• Maximum static pressure of 11.45 mmH2O, ideal for pushing through dense radiators, filters, and narrow ventilation openings.
• Dual Ball Bearing with Brass Housing for long life and reliable operation under 24/7 load and any mounting orientation.
• Electrical characteristics 12 V and 0.6 A with 4 PIN connector, allowing for more precise control through the motherboard or controller.
• Built-in protections – Reverse Polarity Protection, Over Voltage Protection, and Over Current Protection, which minimize risk in case of incorrect connection or unstable power supply.
• Operating temperature range of -10°C to 70°C, making it suitable for warmer rack environments and more unstable premises.
• Long life, backed by a 72 months warranty, so you don’t have to think about replacement soon.

Who it is suitable for

This fan is the most sensible choice for server cases, workstations, and other systems that run non-stop and require serious cooling in a limited volume. It is also suitable for more aggressive airflow builds in desktop cases if you need high CFM and pressure, and don’t care about RGB. If you are looking for a completely silent fan for a home office or HTPC, the range up to 4000 RPM will likely be excessive, and you may prefer a lower RPM model.

The combination of high airflow, serious static pressure, Dual Ball Bearing, and a rich set of protections makes this Arctic server fan a very solid option for reliable and long-term cooling of critical systems.
