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. - The Review

I purchased this TP-101 controller for myself, but I do have a problem. Maybe someone encountered it or has a suggestion.

When I set my fans to 50%, the speeds only drop by about 25-33%. I was expecting a 50% drop at least, maybe as low as 66% drop. I remember this article saying that a 50% voltage drop would drop fan speeds to 1/3 their rating.

I'm not an electrical expert, so I don't really know what's going on here. Does it have something to do with the little blue variable resistors? I don't see the point of dropping a fan speed by 25%, you know what I mean?

Anyway, thanks for the review of this product. Other than the one glitch, I like it a lot.
