In most systems, particularly those that employ an enclosure, some form of forced air cooling will be required to optimize the basic cooling methods available and, ultimately, remove heat from the system. Invariably, this will involve a fan of some kind and there are now many options from which to choose-with each significantly impacting the overall efficiency, effectiveness and lifespan of a system. CUI’s Important Considerations When Selecting a Fan for Forced Air Cooling paper takes a closer look at understanding your design’s needs and requirements, fan performance, and the different fan designs and features to consider for your next project.
