Two or three years ago, controlling the speed of your fans was almost unheard of. All your fans (of which you didn't have many anyway) ran at 12V and if you were lucky you PSU had a thermal sensing fan that adjusted its own speed. Fast forward to now and no enthusiast's PC is complete without fan speed controlling. Even consumer PCs have speed control in some automated form. mCubed's T-Balancer is a product which provdes an extremly high level of control through some clever software. A True Review have a detailed look at it.
After physically setting up the T-Balancer, comes the most unique part, the configuration. What makes the T-Balancer different from other fan controllers with temperature probes is that T-Balancer is highly customizable. On the included CD is a program called T-Balancer Cockpit. In its main screen, the four fan speeds (by percentage, not RPM) are displayed with the temperature of the four temperature sensors. There is also an array of buttons, one of which is the labeled Configuration. Clicking it starts the Configuration Assistant which will take you through 6 steps to setup the T-Balancer. Each step has its own individual buttons that allow you to go directly to the preferred step.
