SKU CH-S78Z-WCNDQ

5V 0.30A 4010 case fan delivers high airflow for compact cooling

  • 5 V 0.30 A low-power operation
  • 4010 form factor fits tight chassis spaces
  • large air volume moves more heat per revolution
  • new condition ensures full factory performance

40 mm 5 V case fan

The DD04010B05U is a 40 mm square case fan that runs on a 5 V supply and draws 0.30 A. It suits compact chassis or small-form-factor builds where a low-voltage, slim-profile cooler is required.

Sustained airflow at constant voltage

At a steady 5 V the motor maintains its rated current without throttling, so the large-volume airflow stays consistent during long sessions. Builds that demand variable speed control or higher static pressure will need a different solution.

Questions about this item

How loud is the 4010 fan during continuous operation?

The 4010 case fan is designed for large air volume cooling, which typically requires higher rotational speeds that produce audible airflow noise.

What power connector does the 5V 0.30A fan need?

The fan runs on 5 volts at 0.30 amps, so it requires a standard 5 V header or adapter capable of supplying at least that current.
