ARCTIC S12038-4K 120mm High Static Pressure Cooling Fan

The ARCTIC S12038-4K is a high-performance 120mm industrial-grade cooling fan engineered for servers, rack systems, data centers, NAS enclosures, and high-density workstation builds. Designed to deliver strong airflow and high static pressure, it is ideal for environments where efficient heat dissipation is critical for system stability and long-term reliability.

Built with a robust 120mm × 38mm thick frame, the S12038-4K provides significantly higher air pressure compared to standard 25mm fans. This thicker design allows it to push air effectively through dense heatsinks, radiator stacks, and restrictive airflow pathways commonly found in server and enterprise systems.

The fan operates at speeds of up to 4000 RPM, delivering powerful and consistent cooling performance under demanding workloads. Its PWM control support enables dynamic speed adjustment based on system temperature, allowing users to balance maximum cooling efficiency with reduced noise during lower load conditions.

Equipped with a dual ball bearing system, the S12038-4K is designed for long service life and reliable 24/7 operation. This makes it especially suitable for mission-critical environments such as data centers and industrial systems where continuous uptime and thermal stability are essential.

With its high static pressure capability, the fan efficiently moves air through tightly packed components, ensuring optimal cooling for CPUs, GPUs, power supplies, and storage systems within constrained chassis designs. This helps maintain stable operating temperatures and improves overall system performance and lifespan.
