Product identity

This ADDA AB5005UX-R0B CWFL1A is a 5 V blower fan intended for notebook or small-form-factor CPU cooling. It draws 0.4 A through a standard 4-pin power connector and uses a Hypro bearing for quieter operation. No LED lighting is included.

Decisive specification

The 4-pin PWM connector is the single detail that determines fit; it provides speed control and monitoring only on headers wired for four wires. Boards with 3-pin headers will run the fan at full speed without regulation. Buyers who need a different connector pitch or voltage cannot use this unit.

Sustained behaviour

Hypro bearing construction reduces friction over long running periods, helping the blower maintain consistent airflow during extended workloads. The 5 V 0.4 A rating keeps power draw modest, so thermal output stays predictable inside tight chassis. Continuous duty is supported within the specified voltage range.

Questions sur cet article

What does the 5V 0.4A rating mean for power draw inside a notebook?

The blower draws 0.4 A at 5 V, which equals roughly 2 W, so it runs directly from a standard notebook fan header without extra power cables.

How does the 4-pin connector control the blower speed?

The fourth wire carries a PWM signal that lets the notebook's thermal controller vary the blower speed between minimum and maximum RPM.

What clearance does the square blower housing need to fit in a laptop chassis?

The square housing sits flat against the heatsink base; measure the available height and footprint in your chassis to confirm the cooler will seat without interference.
