San Ace 120 24V 3-wire case fan

The San Ace 120 109P1224H4D01 is a 120 mm case fan that runs on 24 V DC and draws 0.24 A. Its three-wire lead supplies power, ground and a tachometer signal so the motherboard or fan controller can monitor speed. The 25 mm frame depth fits standard 120 mm mounting points in server chassis, workstations and industrial enclosures. It is sold new and ready for continuous-duty cooling.

120×120×25 mm frame with three-wire monitoring

The square 120 mm frame uses four corner screw holes for secure mounting in any standard 120 mm fan cut-out. The three-wire connector enables real-time RPM feedback without PWM control, making it suitable for systems that rely on voltage regulation or simple speed reporting. Build quality follows San Ace industrial standards for long-life operation in 24 V environments. Buyers needing PWM speed control or a different voltage should look elsewhere.
