After careful consideration I have decided to transfer all hardware review activities to a new domain. I purchased Hardwareasylum.com in 2012 and have been working hard to build a new and improved Ninjalane on that domain. If you are reading this you have reached one of the archived articles, news, projects and/or reviews that were left behind during the site migration.
Please update your bookmarks and be sure to visit the new and improved Ninjalane at Hardwareasylum.com
In this review we will be looking at a very special fan from Cooler Master called the Excalibur. The CM Excalibur is a moderately powerful fan designed to provide high air pressure and still remain quiet under normal operation. The fan does this with a combination of the 9 "sword like" triangle shaped fan blades, unique honeycomb venting, PWM fan control, and a special barometric ball bearing on the fan motor.
High pressure fans can be used for a variety of things from positive air pressure casemods to cooling densely packed or high volume watercooling radiators.
