Ventoinha ARCTIC S4028-15K 40 mm 1400-15000 rpm 19,23 CFM

The ARCTIC S4028-15K is a compact 40 mm server fan engineered for high-performance cooling in tight spaces. With a wide rotational speed range from 1,400 to 15,000 RPM and a maximum airflow of 19.23 CFM, this fan is intended for server and electronics applications that require strong, focused airflow while maintaining a small form factor. It uses a Fluid Dynamic Bearing to reduce noise and extend operational life.

Advantages

The fan delivers a high maximum airflow for its size and supports a broad RPM range to suit different thermal loads. Fluid Dynamic Bearing technology offers quieter operation and improved durability compared with sleeve bearings. Its 40 mm form factor allows installation in compact server chassis and other constrained electronic environments.

How to use

Install the ARCTIC S4028-15K in the designated fan slot of the server or electronic enclosure, observing correct airflow direction and secure mounting to minimize vibration. Connect the fan to the appropriate power header on the motherboard or fan controller, and configure fan speed controls or PWM settings if available to match required cooling performance and noise preferences. Verify that the fan receives adequate power and monitor temperatures after installation.

Recommendations

For reliable operation, keep intake and exhaust paths clear of dust and debris; consider periodic cleaning and, if used in dusty environments, schedule more frequent maintenance. Use appropriate fan speed control settings to balance cooling needs and noise, and ensure the power specifications of the enclosure or controller match the fan's requirements.
