Compact 80 mm 12 V case fan

The SXDOOL 3110KL-04W-B50 is an 80 mm square frame fan designed for 12 V DC systems. It draws 0.30 A for 3.6 W of power and spins at 3250 RPM. The unit suits servers or compact enclosures that need directed airflow in a small footprint.

Two-pin power and 25 mm depth

A 2-pin connector supplies power without speed reporting or PWM control. The frame measures 80 × 80 × 25 mm and weighs 95 g, fitting standard 8025 mounting holes. Operation is rated from -20 °C to 75 °C with a 50,000-hour life expectancy.

Fixed-speed airflow limits

At 3250 RPM the fan delivers 38.8 CFM (1.1 m³/min) at 37.2 Pa static pressure while producing 34 dBA noise. The constant speed cannot be lowered by the motherboard, so noise and airflow remain at peak levels whenever the fan is powered. Builders who need variable speed or quieter idle operation should choose a PWM model.
