The DC 5V 2006 Blower Fan is a compact, low-voltage cooling solution engineered for applications requiring targeted heat dissipation in space-constrained environments, such as consumer electronics, medical devices, and small industrial control systems. Its “2006” designation follows the industry-standard form factor, measuring 20mm in width, 20mm in height, and 6mm in depth—making it one of the slimmest blower fans available, ideal for integration into devices like IoT sensors, wearable tech, or miniaturized power supplies.

Cooling power, a key metric defining its heat dissipation capability, is determined by airflow, static pressure, and heat transfer efficiency—all optimized for the fan’s 5V operating voltage. At 5V, the fan typically operates at 6,000 to 8,000 RPM, delivering airflow ranging from 2.5 to 4.0 cubic feet per minute (CFM). While this airflow volume is lower than larger server fans, it is highly directional: unlike axial fans that spread air broadly, blowers use a centrifugal design to focus airflow into a narrow stream (often with a 90-degree airflow direction change), making them effective for cooling specific components like voltage regulators (VRMs) or small heat sinks in tight spaces. Static pressure is another strength, averaging 15 to 25 Pascals (Pa)—sufficient to overcome airflow resistance in enclosed enclosures (e.g., a compact LED driver housing) where air circulation is limited.

The fan’s cooling power is further enhanced by its brushless DC (BLDC) motor, which operates efficiently at 5V with a current draw of just 0.15 to 0.3A—minimizing power consumption, a critical factor for battery-powered devices (e.g., portable medical monitors) or low-power IoT nodes. Heat transfer efficiency is optimized by the blower’s impeller design: most 2006 models feature curved, backward-inclined blades that reduce turbulence and maximize air velocity, ensuring that cool air directly contacts heat-generating components rather than dissipating into the surrounding space.

Real-world cooling performance tests confirm its efficacy: in a 5V IoT gateway with a 1GHz ARM processor and a small aluminum heat sink, the 2006 blower maintained processor temperatures at 45–55°C under continuous operation (vs. 65–75°C without active cooling), preventing thermal throttling and extending the device’s operational lifespan. Additionally, the fan’s low noise level (20–28 decibels (dB)) makes it suitable for noise-sensitive applications like bedroom air quality monitors or office-based mini-servers.
