Design and Construction

The 40×40mm 5V DC Cooling Fan features a compact housing designed for installation in electronic equipment and confined spaces. Its small form factor allows it to be incorporated into systems where larger cooling fans may not be suitable.

The simple 2-wire connection reduces wiring complexity and makes the fan convenient for basic DC-powered cooling applications. Its lightweight construction is suitable for DIY assemblies and portable or embedded electronic systems.

The compact design allows the fan to be installed in custom enclosures, control panels, robotics projects, computer systems, and other equipment requiring additional airflow.

Working Principle

The cooling fan converts electrical energy from a 5V DC power supply into mechanical rotation. When the appropriate voltage is applied through the two-wire connection, the internal motor rotates the fan blades.

The rotating blades move air through the fan housing, creating airflow around nearby components. This airflow helps remove heat from electronic components and improves air circulation inside enclosed systems.

The fan is designed for basic power-controlled operation through its two-wire connection and does not provide separate speed-control or tachometer feedback wires.
