## Long description

The ARCTIC S4028-6K is a 40 mm server and system fan engineered for efficient cooling in compact spaces. It offers a wide rotational speed range from 250 to 6000 RPM, delivers up to 12.06 m³/h airflow and generates a maximum static pressure of 4.2 mmH2O. The fan uses a Fluid Dynamic Bearing to increase longevity and reduce operational noise, and is finished in black to match typical system interiors.
Advantages
The Fluid Dynamic Bearing improves durability and maintains quieter operation compared with standard sleeve bearings. A broad RPM range allows balancing between low-noise operation and high-performance cooling as needed. Its compact 40 mm diameter makes it suitable for tight server racks, small form-factor PCs and other constrained installations.
Suitable for (tasks / use cases)
