Concentrated Cooling for Micro Electronics
This 20x20x6mm Blower Fan delivers highly targeted airflow to cool overheating components inside extremely confined DIY project enclosures. Unlike standard axial fans that blow air straight through, this centrifugal blower pulls air in from the top and forces it out through a narrow side exhaust at 12000 RPM. This 90-degree airflow redirection makes it the perfect thermal management tool for cooling specific microchips, 3D printer hotends, or compact VR headset internals.
Durable PBT Construction and Low Power Draw
The frame and fan blades are constructed from premium PBT plastic reinforced with 30% glass fiber (PBT+30%GF), ensuring excellent heat resistance and long-term durability. Despite its high-speed performance, the 5V motor is incredibly energy-efficient, drawing a mere 0.04A of current. This low power consumption allows you to run the fan directly from standard microcontroller pins or USB power banks without overloading your circuit.
Pro Tip from Our Technicians
To ensure maximum cooling efficiency, our Sham Shui Po technical team advises leaving at least a 3mm clearance above the fan's circular air intake to prevent suffocating the motor. The included red (positive) and black (negative) wires are ready to be soldered or crimped to your 5V power source. While the manufacturer's spec sheet lists FG, RD, and PWM capabilities for the DC2006 series, please note that this specific 2-wire version operates at a fixed maximum speed when supplied with 5V DC.

FAQ Section
FAQ Section
- Can I power this 5V blower fan directly from a Raspberry Pi?Yes, you can power this 5V blower fan directly from the 5V GPIO pins on a Raspberry Pi. It only draws 0.04A of current, which is well within the safe power limits of standard microcontrollers and single-board computers.
- What is the difference between a blower fan and a regular axial fan?A blower (centrifugal) fan pulls air in through the center and pushes it out through a narrow side exhaust at a 90-degree angle, creating higher pressure. A regular axial fan blows air straight through the frame, which is better for general case ventilation rather than targeted spot cooling.
- Can I control the speed of this 2-wire fan?You cannot control the speed using a dedicated PWM signal wire because this is a 2-wire model. However, you can adjust its speed by varying the input voltage using an external DC motor speed controller or a step-down buck converter.
- Is this fan suitable for cooling a 3D printer hotend?Yes, this ultra-compact 20x20x6mm blower is excellent for cooling small 3D printer hotends or part cooling ducts. Its concentrated side-exhaust is perfect for directing air precisely onto the extruded filament.
- Can I buy this micro blower fan in bulk at your Hong Kong store?Yes, you can purchase this 5V micro blower fan in bulk at Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our store caters to DIY makers and 3D printing enthusiasts, and we can advise you on the best wiring methods for your setup.
