4028 highspeed axial cooling fan acts as a highquality dropin substitute for DBTB0428B2G. Measuring 40×40×28 mm and powered by DC 12V at 1A, this fan generates substantial airflow to remove excess heat from highheatoutput server cabinets and industrial machinery.
Builtin dual ball bearings minimize component wear and extend service life under sustained heavyduty conditions. The 4wire 4Pin PWM connector supports variable speed control, balancing cooling efficiency and operating noise as internal temperatures fluctuate. Reinforced fan housing strengthens vibration resistance during highspeed spinning. Please verify your original fan model, physical size, voltage and pinout prior to ordering to guarantee proper hardware compatibility.
