80 mm case fan for compact builds

The STARTECH FANBOX2 is an 80 mm case fan designed to add targeted airflow inside compatible computer chassis. Its 25 mm thickness fits standard mounting points and the 3-pin power connector works with most motherboard headers or fan controllers. The single-fan package suits builders who need extra cooling in tight spaces.

Ball bearing thermals and acoustics

A ball bearing supports the 3000 RPM spindle speed, delivering 37.3 CFM of airflow at a rated 34 dBA noise level. The bearing choice aims to extend service life while maintaining consistent rotational stability. Power draw is handled through the 3-pin connector without a separate controller.

Sustained load behaviour

Under continuous operation the fan maintains its 3000 RPM rating and 37.3 CFM output, so airflow does not taper off during extended sessions. The 34 dBA acoustic figure reflects steady-state sound rather than a momentary peak. Builders who need variable speed control or larger diameter fans for lower noise at equivalent airflow should look elsewhere.

Questions about this item

How do I mount the 80mm fan using the 3-pin power connector?

Align the four screw holes on the 80 x 80 x 25mm frame with your case mounting points, secure with screws, then plug the 3-pin connector into a motherboard fan header or fan controller.

What maintenance does the ball bearing need over time?

The ball bearing is sealed and requires no lubrication; if noise rises above the rated 34 dBA or airflow drops below 37.3 CFM, replace the fan.

At what point does the 3000 RPM speed become the limiting factor?

Sustained operation at 3000 RPM is the design limit; the motor will reach its thermal and acoustic ceiling before any other component.
