"Tiny Cooling Fan" is the life of the product refers to the radiator working time between failures, high-quality products can reach tens of thousands of hours of life in general. In price and performance similar circumstances, to choose long-life product is clearly better protect our investment. "Tiny Cooling Fan" of life by: motor life, environment, power supply and other factors of the composition. Radiator heat conduction in itself there is a very important factor: the gas flow. The figure above, the gap between the bar and the cylindrical fin fin lies in the different process gas flows. In the cylindrical fin around "Tiny Cooling Fan", because the airflow encountered less resistance, flow more easily be able to take more calories around the cylinder fins, enhanced convection effect. Therefore, in the same heat sink area, the cylindrical cooling effect will be better than the bar.
