80 mm axial fan for 12 V systems

This 80 by 80 by 25 mm axial flow fan runs on 12 V DC and draws 5.40 W. It is built for chassis or equipment cooling where a compact square frame is required. The three-wire lead provides power, ground and a speed signal for monitoring.

Check 12 V header and mounting holes

Verify that your board or controller offers a 12 V fan header with three pins for the tachometer signal. Confirm the chassis has 80 mm mounting points with the standard screw spacing. Ensure the 25 mm thickness fits the available clearance in your enclosure.

Questions about this item

Does the FD8025B12W11-3R21 fan include mounting screws or a power adapter in the box?

The fan is supplied as a single 80x80x25mm axial unit with a three-wire lead; mounting hardware and any adapter cables are not included.

Should I choose the 12V 5.40W version or a lower-voltage model for a standard chassis fan header?

A 12V 5.40W rating matches typical motherboard chassis headers; select this model when your header supplies 12V and you need 80mm airflow.
