Arctic S12038-8K 120 mm 8k rpm Server Fan
FEATURES
New Standards in Energy Efficiency
For the same cooling performance, the S12038 consumes up to 22% less power than competing models, helping improve overall server energy efficiency. This reduced power usage is the result of months of motor optimization by ARCTIC engineers to enhance IT hardware efficiency.
Wide Speed Range (800–8000 RPM)
The S12038-8K offers a broad 800 to 8000 RPM speed range with support for both PWM and voltage control. This flexibility allows precise fan tuning for different server workloads while maintaining efficient cooling performance. 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 Longer Motor Lifespan
Reducing motor temperature by 10°C can nearly double fan lifespan. The S12038-8K features a highly efficient motor with active cooling through an additional impeller integrated into the fan hub for enhanced durability. A protective hub sticker is also included to ensure long-lasting performance in dusty environments.
Optimized for Server Environments
High static pressure is essential for maintaining airflow in compact server systems. The S12038-8K is designed for 3U server chassis and serves as an excellent upgrade or replacement for CPU cooling, radiator setups, and system ventilation applications.
Ideal for Industrial Applications
In addition to server cooling, the S12038-8K is suitable for industrial systems, machine control, and automation environments. Its durable and reliable design ensures stable cooling performance, efficient operation, and minimized downtime across demanding hardware setups.
High Airflow & Static Pressure Performance
The S12038-8K delivers powerful cooling with 37 mmH₂O static pressure, allowing air to efficiently pass through dense heatsinks and radiator fins. With maximum airflow up to 370 m³/h, it rapidly dissipates heat from enclosures, making it ideal for servers, workstations, and industrial cooling applications.
Designed for Continuous Operation
The S12038-8K uses dual high-quality Japanese ball bearings housed in a durable brass casing for enhanced stability, strength, and precision. This robust design minimizes sensitivity to heat and dust while reducing wear during high-speed continuous operation.
Reliable Quality & Long-Term Durability
ARCTIC performs extensive long-term testing under extreme conditions, including 70°C ambient temperatures, heavy dust exposure, and varying humidity levels, to ensure exceptional durability and reliability. Some test fans have operated continuously for more than 15 years. Backed by proven manufacturing quality, the S12038-8K includes a 6-year manufacturer warranty for added confidence.
