SXDOOL 80 mm axial case fan

The SXDOOL FD8025B12W11-3R21 is a 12 V DC axial flow fan measuring 80 by 80 by 25 mm. It draws 5.40 W and uses a three-wire connection for speed monitoring. The unit is supplied new and suits standard 80 mm mounting points in PC cases.

Three-wire speed signal constraint

The three-line interface provides a tachometer output but does not support PWM control. Fan speed is regulated by varying the supply voltage rather than a dedicated PWM signal. Builds requiring four-pin PWM headers cannot use automatic duty-cycle control with this model.

Questions about this item

Should I pick the 8025 model or a different size for my 80 mm mounting holes?

The FD8025B12W11-3R21 measures 80 × 80 × 25 mm, so it fits standard 80 mm case fan mounts. The 8025 designation confirms the 80 mm square footprint and 25 mm thickness.

What does the 5.40 W rating tell me about airflow and noise once the fan is running?

At 12 V the fan draws 5.40 W, which drives the axial flow motor to move air through the 80 mm frame; power draw at this level typically yields a balance of solid airflow and moderate noise for case cooling.
