Compact 80 mm axial fan for tight builds

This 80 mm square axial cooler fits standard 80 mm mounting points in small-form-factor cases or rack enclosures. It runs on a 12 V supply drawing 0.3 A through a two-pin connector. The non-LED black frame keeps the visual profile neutral for workstations or servers.

Airflow headroom for targeted component cooling

The DC motor with dual-ball bearings delivers steady airflow across heatsinks, VRM zones or drive bays where larger fans cannot fit. At 0.3 A the current draw is modest, leaving ample headroom on a typical 12 V rail. It is not suited for high-static-pressure radiators or full-case ventilation duties.

Dual-ball bearing reliability and simple wiring

The two-ball bearing design reduces friction wear compared with sleeve alternatives, extending service life in continuous operation. A two-wire, two-pin lead plugs directly into motherboard or controller headers without PWM control. The 25 mm thickness matches common slim-fan brackets for straightforward mounting.

Questions about this item

Will the 2-pin connector on the 3110KL-04W-B50 work with the 3-pin headers on my older motherboard?

The 2-pin plug fits a 3-pin header by leaving the sense pin empty; the fan will run at full 12 V speed without PWM control.

How can I confirm the 80 mm fan is spinning correctly after installation?

Power the system and visually check blade rotation through the case grille; the 2-ball bearing should run smoothly without rattling at 12 V.

Does the 3110KL-04W-B50 include mounting screws or must I supply my own?

The package contains only the 80×25 mm black axial cooler with 2-wire lead; 80 mm mounting screws are not included and must be sourced separately.
