This 40mm 12V DC Fan is a tiny, compact fan designed for very small parts like Extruders or drills in 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.

For extra protection, we also sell the 40x40mm Fan Guard, which protects the blades from foreign objects like wires or fingers, and also protects those foreign objects from the blades.

Typical Applications for 40mm 12V DC Fans:

These 40mm 12V DC Fans are primarily used in machines in which small, specific parts need to be cooled, whilst the rest of the machine or enclosure needs to stay warm – just like within 3D Printers. Their 3 pin power connection also allows for an optional S pin, providing complete control over the speed of the fan as well. This can help you maintain the perfect temperature for your parts, which often translates to great results in 3D printing and similar machines.
