40 mm 12 V 4-wire case fan

The ADDA AD0412XB-B5BDS is a 4028 form-factor fan that runs on 12 V and draws .80 A. Its four-wire connector supports PWM speed control for precise airflow management. It fits compact chassis and small-form-factor builds where space is limited.

Sustained load behaviour

At continuous operation the motor maintains its rated current without thermal throttling. The PWM circuit keeps speed stable under constant back-pressure from dense heatsinks or filters. Bearing noise stays consistent during extended duty cycles.

Questions about this item

How much current does the AD0412XB-B5BDS draw at 12 V when running continuously?

The fan is rated at 0.80 A on a 12 V supply, so sustained operation will draw that current.

What connector must my motherboard or fan controller provide for the four-wire lead?

A standard 4-pin PWM header is required to power and control the fan.
