24V DC Inverter Case Fan

The SunnyStar Co., Ltd MMF-12C24DH-RA4 is a 120mm square frame fan built for 24 volt DC systems. It draws 0.27A and uses a three-wire power connector. The unit targets industrial equipment or server chassis that require a 38mm thick cooling solution.

Verify Voltage and Connector

Confirm your power source delivers 24V DC before installation. The three-pin lead provides power and tachometer signal only; it does not support PWM speed control. Ensure the mounting holes match a standard 120mm pattern and that the 38mm depth clears adjacent components.

Ball Bearing 38mm Build

A ball bearing motor supports continuous operation in demanding environments. The black plastic frame measures 120mm by 120mm by 38mm and carries no LED lighting. The three-wire cable exits the frame for direct connection to a compatible header or terminal block.

Questions about this item

Does the MMF-12C24DH-RA4 come with mounting screws or a fan grille, or do I need to supply them?

The package contains the 120 mm by 120 mm by 38 mm fan with its attached 3-pin power lead; mounting hardware and any grille are not included and must be sourced separately.

How do I decide between the 24 V 0.27 A MMF-12C24DH-RA4 and a 12 V alternative for the same 12038 frame?

Choose the 24 V model only if your system provides a 24 V fan header or an inverter rail; a 12 V version will not run correctly on 24 V and vice versa.

What does the 0.27 A rating mean once the fan is installed in a 24 V chassis?

At 24 V the fan draws 0.27 A, giving a steady power draw that the motherboard or controller must be able to supply continuously on the 3-pin header.
