120 mm 3-wire server cooler

This 120 x 120 x 25 mm case fan runs on 12 V DC and draws 4.7 W. The three-wire connection provides power and speed reporting for basic monitoring. It fits standard 120 mm mounting points in server chassis or workstation cases.

Sustained-load behaviour

At continuous operation the fan maintains a steady airflow determined by its fixed 12 V supply. The 3-wire design lacks PWM control so speed does not scale with temperature. Acoustic output and bearing wear remain constant during extended duty cycles.
