Arctic S12038-4K 120 mm 4k rpm Server Fan ( 3 Pack )

FEATURES

New Standards in Energy Efficiency

For the same cooling performance, the S12038 consumes up to 12% less power than leading competitors, helping improve overall server energy efficiency. This reduced power consumption is achieved through months of motor optimization by ARCTIC engineers to maximize IT hardware efficiency.

Wide Speed Range (600–4000 RPM)

The S12038-4K supports a broad 600 to 4000 RPM speed range with both PWM and voltage control for precise cooling adjustment. This flexibility ensures optimal cooling performance under varying server workloads. The standard 4-pin connector also supports 2-pin and 3-pin headers, while the 30 cm cable provides flexible installation options.

Active Cooling for Extended Motor Lifespan

Lowering motor temperature by 10°C can nearly double operational lifespan. The S12038-4K features a highly efficient motor with active cooling through an additional impeller integrated into the fan hub for improved durability. A protective hub sticker is also included for reliable long-term performance in dusty environments.

Optimized for Server Environments

High static pressure is essential in compact server systems to maintain proper airflow. The S12038-4K is designed for 3U server chassis and works perfectly as an upgrade or replacement for CPU cooling, radiator applications, and system ventilation.

Ideal for Industrial Applications

Beyond server cooling, the S12038-4K is also suitable for industrial systems, machine control, and automation environments. Its reliable and durable design ensures stable performance, efficient cooling, and reduced downtime across demanding hardware applications.

High Airflow & Static Pressure Performance

The S12038-4K delivers 11.45 mmH₂O static pressure, enabling efficient airflow through dense heatsinks and radiator fins. With maximum airflow up to 180 m³/h, it quickly dissipates heat from enclosures, making it ideal for servers, workstations, and industrial cooling systems.

Built for Continuous Operation

The S12038-4K uses dual high-quality Japanese ball bearings housed in a durable brass casing for enhanced stability, strength, and precision. This design minimizes sensitivity to heat and dust while reducing wear during high-speed continuous operation.

Reliable Quality & Long-Term Durability

ARCTIC conducts extensive long-term testing under extreme conditions, including 70°C ambient temperatures, heavy dust exposure, and varying humidity levels, to ensure outstanding durability and reliability. Some test fans have operated continuously for more than 15 years. Backed by proven manufacturing quality, the S12038-4K includes a 6-year manufacturer warranty for added peace of mind.
