4715VL-04W-B86-E53 NMB 12V 3.60A 120mm 12038 DC Axial Fan

Description

The NMB 4715VL-04W-B86-E53 is an ultra-high-performance DC axial fan, commonly referred to as a “12038” size, engineered for the most demanding thermal environments. This 120 x 120 x 38 mm unit features NMB’s signature precision dual ball bearing system and a specialized 5-blade high-torque impeller designed for maximum air displacement. Operating at 12 VDC with a heavy-duty current draw of 3.60 A (43.20 W), it delivers a super-high speed profile to produce an immense 200.30 CFM of airflow. The 4-wire interface provides both a Speed Sensor (FG) and Pulse Width Modulation (PWM) input, enabling intelligent, demand-based speed control. Built with a brushless DC motor and advanced electronic protection, this fan is a critical cooling component for enterprise-grade servers, high-power industrial inverters, and telecommunications infrastructure requiring extreme heat dissipation.
