Compact server cooling fan

The Graviton 2106KL-04W-B59 is a 12 V DC axial fan built for computer enclosures and server chassis. It draws 0.18 A and fits the standard 50 mm square footprint with a 15 mm profile.

Compatibility check

Verify that your system provides a 12 V DC header or lead with a three-wire connector for speed monitoring. Confirm the mounting holes match a 50 mm square pattern and that 15 mm clearance exists between the fan frame and adjacent components.

Thermals and acoustics

The plastic frame and impeller keep weight low while moving air through tight server bays. Expect modest airflow suitable for localized component cooling rather than high-static-pressure radiator duty. Operational noise is typical for a small 12 V fan running at constant voltage.

Questions about this item

What comes in the box and what must I buy separately?

The fan unit is included in the package; a 12 V power source and mounting screws are not supplied.

Which version of the 2106KL-04W-B59 should I choose?

Only the 12 V 0.18 A model with three-wire lines is offered.

What does the 0.18 A rating mean once the fan is installed?

It draws 0.18 A at 12 V, so the system fan header must supply at least that current.
