Server Laptop Fan 5V 4-Wire

The ADDA AB08505HB120B00 is a DC cooling fan rated at 5 volts and 0.50 amperes with a four-wire connector. It is designed for server or laptop chassis that require a compact axial fan with speed monitoring and PWM control.

Practical limits of the 5V four-wire interface

The fan operates only from a 5 V supply and draws up to 0.50 A, so the host header must provide that current. The fourth wire enables speed reporting and PWM duty-cycle control; systems without a matching four-pin header cannot use the monitoring function. Buyers needing a different voltage or a three-wire connector should select another model.

Questions about this item

Which voltage and current rating matches my server laptop?

This fan runs on DC 5 V and draws 0.50 A, so it fits systems that supply exactly those values on the fan header.

What does the 4‑wire connection do once installed?

The fourth wire carries a PWM signal, letting the motherboard adjust fan speed dynamically based on temperature.
