12V DC Small Cooling Fan for Electronics Projects

The 12V DC Small Cooling Fan provides airflow for compact electronics assemblies. With a nominal 40mm frame size and 10mm thickness, it is useful for projects that need ventilation without a large fan.

This fan operates from a suitable 12V DC power supply and has a rated current of 0.16A. It can help circulate air inside an enclosure or move warm air through a ventilation opening. Cooling performance depends on the enclosure design, airflow path and heat produced by the components.

Compact 40 × 10mm Size

Small enclosures often have limited room for cooling accessories. This fan’s compact dimensions make it a practical option for compatible project boxes, control assemblies and custom electronics housings.

Before installation, check the available space and mounting-hole positions. Leave enough clearance around the fan so that its blades can rotate freely and air can pass through the opening.

Applications

The 12V DC Small Cooling Fan can be used in:

• DIY electronics enclosures
• Small control-panel assemblies
• Compatible power-supply housings
• Robotics and automation projects
• Custom ventilation systems
• Student electronics prototypes

Select the fan according to your project’s cooling requirements. For components that generate significant heat, suitable heatsinks and additional airflow may also be necessary.

Technical Specifications

Power and Installation Guidance

Use a regulated 12V DC supply with enough current capacity for the fan and any other connected devices. Check the fan’s polarity markings before connecting power.

For Arduino or ESP32 projects, use a suitable transistor or MOSFET driver circuit to switch the fan. Do not power it directly from a microcontroller GPIO pin.

Position the fan to create a clear airflow path through the enclosure. Secure it using suitable mounting hardware and keep loose wires away from the rotating blades. If airflow-direction arrows are present on the housing, use them to guide installation.
