Zyvpee DF1202512SEL 120mm 25mm 2-pin case fan

120 mm DC axial case fan

The Zyvpee DF1202512SEL is a 120 mm square DC axial fan designed for standard case ventilation. It suits builders who need a simple 12 V airflow device without lighting or speed signalling. The 2-pin connector provides power only, so the fan runs at a fixed voltage unless the motherboard or controller adjusts it externally.

Sleeve bearing and 2-pin power

A sleeve bearing keeps the rotor running with a thin oil film, which is quieter at low speed than some alternatives but may wear faster in horizontal orientations. The black frame measures 120 by 120 by 25 mm and carries two wires for 12 V DC input. No PWM or tachometer line is present, so the system cannot monitor or regulate speed automatically.

Fixed-speed 1.92 W limit

At 12 V the unit draws 0.16 A for 1.92 W, a modest figure that fits most fan headers but offers no headroom for higher static pressure. Without a third wire the fan cannot report RPM, and voltage control is the only way to lower noise. Buyers who need variable speed curves or RPM feedback should choose a 3-pin or 4-pin model instead.
