Description
NMB 03828DA-12Q-BU-01 is a 12VDC 38x28mm Axial Fan optimized for high-density thermal management in space-constrained environments. This compact cooling solution utilizes a brushless DC motor integrated with a precision dual ball bearing architecture to ensure long-term reliability and reduced thermal impedance. The aerodynamic design of the UL94V-0 plastic impeller is engineered for structural rigidity, allowing the fan to overcome significant system resistance. Operating at a rated current of 0.75A with a power consumption of 9.0W, it features a 4-wire PWM interface for dynamic speed modulation, making it an ideal replacement fan for high-performance server nodes and power supply units requiring efficient heat dissipation.
