SXDOOL EF50201S1-C000-G99 50×20 mm 12 V 1.02 W case fan

Compact Maglev Blower

The SXDOOL EF50201S1-C000-G99 is a 50 by 20 mm turbine blower designed for tight spaces such as small-form-factor PCs or projector chassis. It operates on 12 V DC and draws 1.02 W through a three-wire lead. The County Maglev bearing reduces friction for quiet, long-life operation in CPU, IC or power-supply cooling roles.

Steady Thermal Output

Because the impeller uses maglev suspension, rotational stability remains consistent during extended duty cycles rather than degrading as sleeve bearings can. The low 1.02 W power draw means heat contribution to the loop is minimal, so the fan sustains its airflow profile without adding measurable thermal load. Continuous 12 V operation keeps the blower at its rated curve for the duration of the workload.

Three-Wire Integration

The three-wire connector supplies power, ground and a tachometer signal, allowing the host system to monitor speed and adjust PWM control if the header supports it. At 50 mm square and 20 mm thick the unit fits cramped ducts where conventional axial fans cannot mount. Buyers needing a larger diameter, higher static pressure or a two-pin power-only interface should look elsewhere.
