24V DC 120mm Cooling Fan — Efficient cooling for inverters and electrical enclosures
Ever wondered what a welding inverter or electrical panel looks like after running at full load for hours? It heats up, efficiency drops, and in extreme cases, it fails completely. A quality 24V DC fan isn’t just an optional accessory — it’s what keeps your equipment alive.
The 12038 model running at 24V and 0.30A delivers exactly what you need: high airflow, stable performance at 3000 RPM, and a noise level that won’t drive you crazy in the workshop.
Why choose this model? (Key benefits):
- Universal 120x120x38mm format — The standard size for welding inverters, battery chargers, and electrical panels. Installs directly without any modifications.
- Constant 3000 RPM speed — Sufficient airflow to keep temperatures under control even during continuous operation, not just at startup.
- Low power consumption: 0.30A / 7.2W — Places no significant load on your existing 24V power supply.
- Quiet operation — Quality bearings that reduce vibrations. You won’t have to put up with an annoying background hum while you work.
- 24V DC voltage — Directly compatible with standard power sources in industrial inverters, UPS units, and distribution boards.
Details and Performance
The 24V DC motor ensures a quick startup and stable rotational speed regardless of the ambient temperature. The 120mm diameter blades are engineered for maximum axial flow — air is pushed straight through the equipment’s cooling channels rather than being scattered sideways. The 38mm depth allows for mounting in tight spaces without compromising on airflow.

Frequently Asked Questions
Is it compatible with my welding inverter?
If your inverter uses a 120x120x38mm fan powered at 24V DC, yes — it drops right in as a direct replacement for the original. Just check your mounting hole dimensions (standard 105mm screw spacing).
Can I power it from a 12V source instead of 24V? — Places no significant load on your existing 24V power supply.
No. The motor is designed exclusively for 24V DC. At a lower voltage, it either won’t start or will run too slowly to provide effective cooling.
How quiet is it in practice?
At 3000 RPM, it produces a discrete background sound similar to a desktop PC running normally. It isn’t completely silent, but it won’t interfere with your work in the workshop.
What should I do if the fan vibrates after installation?
Check that the mounting screws are tightened evenly and that nothing is obstructing the blades. A slight vibration right at startup is completely normal and disappears after a few seconds.
