Compact 40 mm case fan

The 4015 model measures 40 by 40 by 15 mm and runs on 12 V at .26 A. Its four-wire connector supports PWM speed control and tachometer feedback for precise airflow management in tight chassis spaces.

Four-line connector benefit

The extra wires enable motherboard-controlled fan curves and real-time RPM monitoring. Builders needing three-pin voltage control or larger frame sizes will need a different fan.
