The Sunbeam Theta TP-101 fan controller is a little different than you might expect.  It’s a PCI card, with a satndard molex power connector and 8 fan connectors.  All the fans in your system connect to it, and are controlled via installed software.  Read the full review at Big Bruin.
“Sunbeamtech has offered the typical fan controller (rheobus) in a variety of styles in the past, but the software based Theta TP-101 is much different. Instead of using knobs to mechanically vary resistance, a Windows interface is used to automate this through software, while providing on screen information for up to eight fans and eight thermal probes.”
