Cooler Master Excalibur Case Fan Review
 

Fans come in all different shapes and sizes, and what started as a pretty common design quickly transformed into a technical art used to create specialized fans for special purposes. Some fans are designed to cool heatsinks and direct airflow over a certain area, while others might be simple case fans designed to move massive amounts of air. http://www.ninjalane.com/reviews/cooling/cm_excalibur/
