Product information

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)

  • Cooling compact servers and network equipment
  • Small form-factor PCs and industrial controllers
  • Point-of-sale systems, embedded systems and chassis with limited fan clearance

How to use

Install the ARCTIC S4028-6K in the designated fan slot or bracket within the chassis, ensuring correct airflow direction for your cooling layout. Connect to a compatible fan header or power source matching the fan's voltage and control specifications. Secure the fan with screws or mounting hardware appropriate to the device. Configure fan speed control through the system BIOS, fan controller or software to take advantage of the 250–6000 RPM range.

Usage recommendations

Choose lower RPM settings for quieter background operation and increase RPM when higher cooling performance is required. Regularly inspect and clean the fan from dust to maintain airflow and prolong bearing life.
