The Zalman fan controller offers style and flexibility along with easy control features. Although the controller only offers 7watt power for the 3pin connectors, which could hold back some higher CFM fans. The only set back I really encountered would be the installation. It works nicely unless you have a case with the easy in and out slides on it, which in my installation I ended up having to drill a couple of holes in order to mount it because there was no way to attach the slides to the fan controller.
