Description
The NMB 3115RL-04W-B96-E5F is an extremely high-performance 12V DC axial cooling fan from NMB Technologies Corporation, measuring 80mm x 80mm x 38mm. This fan is specifically designed for demanding thermal management in servers, workstations, and high-density electronic equipment that requires maximum airflow and static pressure. Operating at a rated current of 3.00A (36W), it achieves an exceptionally high rotational speed of 8600 RPM, delivering a powerful 135 CFM of airflow. Due to its high performance, it has a corresponding noise level typically around 62.5 dBA. Equipped with double ball bearings, it offers an ultra-long operational life of 180,000 hours. The fan typically utilizes a 4-wire connector to support PWM automatic speed control and often includes a speed signal (tachometer) output, ensuring precise control and monitoring in critical applications.
