Arctic Server Fan 120x120x38 Dual Ball - S12038-8K - ACFAN00294A

Arctic Server Fan 120x120x38 Dual Ball - S12038-8K is a serious server fan that can easily pass as a high-performance solution for cases with limited airflow or tightly packed hardware. With a size of 120 x 120 x 38 mm and a range of 800 to 8000 RPM, it is designed to move a huge amount of air under high pressure. The dual bearing 2 Ball Bearing with a brass housing is oriented towards 24/7 load and long life, not towards a “quiet gamer” aesthetic. There is no RGB, it is black, and it is designed to get the job done in server, industrial, or heavy enthusiast configurations.

What you get

The main weapon here is airflow – up to 220 CFM, combined with maximum pressure 37 mmH2O, which is exactly what you need for dense radiators, closed server chassis, or tight RAID arrays. The range of 800–8000 RPM gives you flexibility – from relatively quiet mode to “turbine” when the situation demands it. With a consumption of up to 3.2 A and a 4-pin connector, you need to ensure that the controller or motherboard can supply enough current, but in return, you get a fan that is not afraid of high static pressure and warm air. The operating temperature range of -10°C to 70°C and materials with a flammability class of UL 94: V-0 are clear indications that this model is designed for serious environments where reliability is more important than appearance.

• High-performance server fan with a size of 120 x 120 x 38 mm, suitable for cases and chassis where standard 25 mm thick fans do not fit.
• Range of 800 to 8000 RPM, which means wide control from a more peaceful airflow to extreme cooling when needed.
• Maximum airflow up to 220 CFM, providing aggressive expulsion of warm air from tightly packed server configurations.
• Static pressure up to 37 mmH2O, ideal for radiators, filters, and narrow air channels where many other fans “die”.
• Reliable 2 Ball Bearing bearing with brass housing (Dual Ball Bearing with Brass Housing), optimized for 24/7 operation and vertical/horizontal mounting.
• 4-pin connector and consumption of up to 3.2 A, which requires a stable fan header but allows for powerful operation and control.
• Integrated protections – Reverse Polarity Protection, Over Voltage Protection, Over Current Protection – for lower risk of damage in case of power supply issues.
• Operating temperature range of -10°C to 70°C and flammability class UL 94: V-0, suitable for server and industrial environments.
• Length of cable 300 mm and clean black design, without RGB, focused entirely on functionality and easy cabling.
• Long warranty of 72 months, indicating confidence in durability during long-term use.

Who is this suitable for

This fan is for server and workstation configurations, for racks, NAS cases, and industrial solutions where cooling is a priority over noise. It also works for enthusiasts with dense water radiators or hot GPU/CPU zones in more extreme builds. If you are looking for a quiet, “invisible” fan for a standard home office or light gaming, this is rather overkill and may be louder than you prefer.

The combination of thickness 38 mm, huge airflow, and high static pressure, along with the dual bearing and long warranty, makes Arctic Server Fan S12038-8K a very serious tool when you just need to keep the system cool under any conditions.
