Description
The NMB 3115RL-04W-B76-E02 is an extremely powerful 12V DC axial cooling fan measuring 80mm x 80mm x 38mm. Operating at a rated current of 1.60A (19.2W), this fan is engineered for critical thermal management where maximum airflow and static pressure are paramount. It achieves a very high rotational speed of 6500 RPM, delivering approximately 116 CFM of airflow with a high static pressure (exact value not always specified for -E02, but typically very high for this current, often exceeding 1.0 inch-H2O). Its noise output is 57.0 dBA or higher, reflecting its immense performance. The fan is equipped with ball bearings for a long operational life, typically 180,000 hours. Connectivity is via 4-wire leads, which include a pulse sensor for speed monitoring and a PWM input for precise speed control. Integrated features also include auto-restart and polarity protection, ensuring robust and controlled performance in demanding cooling scenarios.
