Within the PC market fan controllers are a very niche product, and certainly the majority of users will never need them. Yet there is still a very strong demand for high quality fan controllers among the PC enthusiast community, particular those who have a lot of fans, who often also engage in water cooling. As a result of fan controllers being a niche market there aren't many companies that sell fan controllers as their specialty. Indeed case manufacturers like BitFenix and Fractal design produce some fan controllers because they are accessories to their main products, PC cases. And recently we have started seeing some case manufacturers integrated quite basic and primitive fan controllers into the design of the case with "low/medium/high" switches or dials for up to 5 or 6 case fans. Yet if you are "serious" about your system, fans and cooling, those are very often not good enough.
