70 mm 24 V dual-ball case fan

This SXDOOL AFB0724HH is a 70 mm DC case fan built for 24 V systems. It spins at 3500 RPM and moves between 55 and 60 CFM while producing 35 to 40 dBA. The two-pin connector supplies power without PWM control. Dual ball bearings support continuous operation in industrial cabinets or inverter enclosures.

Suited for 24 V cabinets needing steady airflow

Installers fitting inverter power cabinets or similar 24 V equipment will match the voltage and current draw directly. The fixed 3500 RPM speed and two-pin wiring suit always-on cooling where variable control is not required. Builds that need PWM regulation, lower noise floors or a different supply voltage should choose another model.

24 V 0.22 A two-pin power requirement

The fan draws 0.22 A at 24 V DC through a two-pin connector, consuming about 5.28 W. This single electrical spec decides whether the unit fits the target power rail and header. Verify the system provides a 24 V two-pin source before ordering.

Questions about this item

What does the 2-pin power connector limit for the afb0724hh?

The 2-pin connector supplies 24 V DC at 0.22 A without a tachometer or PWM signal, so speed reporting and motherboard fan-curve control are not possible.

What clearance does the 70 × 70 × 25 mm frame need to mount?

It requires a 70 mm square cut-out with 25 mm depth behind the panel, plus room for the two-wire lead to exit without sharp bends.

How is the afb0724hh wired in, and what mistake do installers make?

Connect the two leads to a 24 V DC source observing polarity; the common error is reversing the wires, which prevents the fan from spinning.
