The 2-Inch Cooling Fan with Heatsink is a compact and effective active cooling solution designed for heat-sensitive components such as microcontrollers, voltage regulators, motor drivers, and small embedded systems. This combo unit integrates a small yet powerful 5V or 12V fan (depending on model) with an aluminum heatsink to significantly enhance heat dissipation and maintain stable performance under load.

Perfect for use in Arduino, Raspberry Pi, ESP32, and custom PCB projects, this cooling module helps extend the lifespan and reliability of your electronic components by keeping them within safe operating temperatures.

How It Works:
The heatsink absorbs heat from the component it's attached to, while the fan actively pushes air across the aluminum fins to accelerate cooling through convection. The combination of passive and active cooling makes this unit ideal for situations where passive heatsinks alone are insufficient.

Specifications:

• Fan Size: 2 inches (approx. 50mm x 50mm)

• Power Supply: 5V or 12V DC (depending on model)

• Fan Connector: 2-pin or 3-pin (varies)

• Heatsink Material: Anodized Aluminum

• Mounting: Pre-applied thermal adhesive pad or mounting holes (based on model)

• Fan Speed: 3000 – 6000 RPM (typical)

• Airflow: Approx. 5–10 CFM

• Noise Level: Low-noise operation (~20–30 dBA)

Applications:

• Microcontroller cooling (Arduino, ESP32, STM32, etc.)

• Raspberry Pi or SBC heat management

• Power transistors, MOSFETs, and voltage regulators

• Compact PCBs and robotics systems

Limitations:

• Requires a DC power supply to operate the fan.

• Not waterproof—indoor use only or in enclosures with proper protection.

• Fan orientation matters—ensure proper airflow direction for effective cooling.

• Adhesive-based mounting may not be suitable for high-vibration environments (use screws if available).
