12V 40x40x10mm Axial Cooling Fan Brushless motor sleeve bearing For 3D Printer Robotics CPU Cooler Radiator Fan

This 40mm 12V DC Fan is a tiny, compact fan designed for very small parts like Extruders or drills in CNC-based machines like 3D Printers. These parts often require cooling, but are so small that a typical fan would be impractical – either taking up too much space in a compact area or providing too much cooling for the surrounding components. In such scenarios, these compact 40mm fans are the ideal size to provide sufficient, controlled cooling to small parts.
