Cooling Fans Price in BD (Bangladesh) 2026

Cooling Fans for Science Projects, Robotics, and DIY Electronics

Whether you are building a school science model, an automated Arduino system, or a high-performance DIY electronics project, reliable heat dissipation is essential. Excessive heat can impair sensitive microcontrollers, burn out motor drivers, and reduce the overall lifespan of electronic circuits. At Biggan Project, we offer a comprehensive selection of cooling fans tailored specifically for students, young innovators, hobbyists, and robotics enthusiasts across Bangladesh.

From mini 5V DC micro-fans for compact enclosures to powerful 12V high-CFM brushless fans for heavy-duty setups, finding the right component for your prototype is now fast and affordable.

Choosing the Right Cooling Fan for Your DIY Circuit

Not all thermal management solutions fit every setup. Depending on your power source and system requirements, you can select from several popular variations available at বিজ্ঞান প্রজেক্ট:

• 5V DC Cooling Fans: Ideal for microcontrollers like Arduino Uno, NodeMCU ESP8266, ESP32, and Raspberry Pi boards. These can easily be powered directly via USB ports or 5V power supply rails.
• 12V DC Brushless Fans: Perfect for 3D printer hotends, custom power supply enclosures, audio amplifiers, and motor driver heat sinks that require higher airflow.
• 24V & AC Cooling Fans: Designed for industrial automation models, heavy-duty relay units, and large-scale DIY electronics rigs.
• Blower / Radial Fans: Excellent for focused air delivery in narrow channels, such as 3D printer nozzle cooling and concentrated heat sink vents.

Frequently Asked Questions (FAQ)

How do I power a 5V cooling fan using an Arduino?

You can connect the positive wire (red) of a 5V DC fan to the 5V pin on the Arduino and the negative wire (black) to the GND pin. For automated control based on temperature sensors like the DHT11 or LM35, connect the fan through a transistor (like NPN TIP120 or BC547) or a 5V relay module.

Can I run a 12V fan with a 9V battery for a school project?

Yes, a 12V DC fan will run on a 9V battery, but it will spin at a slightly lower speed and move less air. For optimal performance in science competitions, using a 12V DC power adapter or a 12V Li-ion battery pack is recommended.

What is the difference between an axial fan and a blower fan?

An axial fan blows air straight out along its axis, making it ideal for general ventilation inside an enclosure. A blower fan draws air in from the center and forces it out through a narrow nozzle at a right angle, making it superior for targeted spot cooling.
