Compact 80 mm chassis fan for tight builds

The SXDOOL U80R12MUA-57 is an 80 mm square frame fan designed for small-form-factor cases and legacy mounting points where larger fans will not fit. It runs on 12 V DC drawing 0.25 A through a two-pin connector with an 18 cm lead. The hydraulic bearing is rated for 50000 hours of operation.

2600 RPM speed with 30–35 CFM airflow

At a nominal 2600 RPM the fan moves between 30 and 35 CFM, a figure that decides whether the part can satisfy the thermal budget of a given heatsink or chassis layout. The speed tolerance of plus or minus five percent keeps output predictable across units.

25–30 dBA acoustic profile under continuous spin

Sustained operation at the rated speed produces a noise floor of 25 to 30 dBA, reflecting steady-state output rather than a brief startup spike. The fluid-dynamic bearing maintains consistent rotational stability throughout the 50000-hour design life without speed drift.

Questions about this item

How much air does the 30-35 CFM rating actually move inside a typical case?

At 2600 RPM the fan delivers 30-35 CFM, enough to push a steady stream of cool air through drive cages or a compact heatsink in an 80 mm mount.

What does the 2-pin connector limit compared with a 3- or 4-pin header?

The 2-pin plug supplies 12 V at 0.25 A with no PWM or tachometer signal, so the motherboard can only control speed by varying voltage.

Will the 80 mm x 10 mm frame and 18 cm leads fit my tight chassis?

The frame measures 80 mm square by 10 mm thick with 18 cm wires, matching standard 80 mm mounting holes and reaching most nearby headers.
