DBPU0428B2U high-performance axial cooling fan is a supercharged 4028 fan designed for 1U server power supplies, network devices and RC cooling projects. It runs on DC12V power input with 3.5A rated current and 42W power consumption, reaching extreme speed of 33000RPM to deliver massive static pressure and concentrated airflow. Adopting dual ball bearing construction, this fan maintains stable rotation under high-speed working conditions and extends service life. The 4-wire PWM interface allows host systems to dynamically adjust fan speed according to temperature. If your original fan cannot exhaust concentrated heat, produces abnormal noise or triggers fan stall warnings, this replacement fan protects your power modules and network hardware from thermal overheating damage.
