Description
The SUNON 40281BX-Q000-S99 is a high-performance DC axial fan engineered specifically for high-density server environments and industrial applications requiring exceptional static pressure. Built upon a robust Dual Ball Bearing architecture, this unit ensures long-term reliability and structural rigidity even under continuous high-speed operation. The 12VDC motor is optimized for high-torque output, consuming 8.16W to drive the impeller at velocities necessary to overcome significant system impedance. Featuring a 4-wire interface with PWM speed control, it allows for precise thermal management, dynamically adjusting airflow based on system load to optimize the balance between cooling efficiency and power consumption. The aerodynamic blade design minimizes turbulence while maximizing air penetration in restricted chassis.
