170 mm 24 V industrial case fan

The SXDOOL MADC24H7C-943 is a 170 mm square frame fan built for 24 V DC systems. It draws 1.05 A and delivers 25.2 W of continuous power. Dual ball bearings support a rated speed of 3800 RPM with a ten percent tolerance. The two-pin connector supplies power without speed reporting or PWM control.

Suits inverter and cabinet cooling.

This unit targets integrators cooling ABB inverters or similar 24 V enclosures where high static pressure and 280.1 CFM airflow are required. The fixed two-wire interface makes it unsuitable for motherboards that expect a third wire for tach feedback or a fourth for PWM duty-cycle control. Builders needing variable speed governed by a PC header should look elsewhere.

280.1 CFM at 55 dB(A) with 50 mm depth

At full rated voltage the fan moves 280.1 CFM while producing 55 dB(A) of acoustic noise. The 172 mm by 151 mm by 50 mm frame fits standard 170 mm mounting patterns but exceeds the depth of many slim chassis designs. Headroom is ample for dense heat-exchanger stacks; the limit appears in noise-sensitive or space-constrained installations where lower airflow or thinner profiles are preferred.

Questions about this item

What voltage power supply must I already have to run this 24 V fan?

The fan requires a 24 V DC source capable of delivering 1.05 A, so your power supply must provide a 24 V rail rated for at least 25.2 W.

Can I connect this 2-pin fan to an older 3-pin or 4-pin motherboard header?

The fan uses a 2-pin connector; it will physically fit a 3-pin or 4-pin header if the keying matches, but speed reporting and PWM control will not be available.

How do I confirm the fan is spinning at its rated 3800 RPM after installation?

With only two wires the fan cannot report speed; you must verify operation by measuring airflow of roughly 280.1 CFM or by listening for the 55 dB(A) acoustic level at full voltage.
