DC Fans have been the go-to solution in a designer’s thermal management toolbox for years, providing efficient cooling for products requiring the removal of heat from a few watts to several hundred watts. To ensure that the appropriate fan is selected, it is important to align the system’s cooling needs with the fan’s airflow characteristics.

With knowledge of the required airflow and pressure, the proper fan (or fans) can be selected to provide adequate cooling. Operating fans in parallel or in series provides designers with additional options to meet the thermal requirements of their application when a single fan may not be sufficient. CUI’s line of dc axial fans features a variety of performance ratings, allowing designers flexibility when choosing between fan size, power consumed, audible noise produced, and more.

In the latest CUI Insights blog, Bruce Rose covers the basics, including proper calculation of airflow and air pressure parameters, aligning airflow requirements with a fan’s operating curve, the implications of running fans in parallel or series, and the effects of fan speed.
