I use a Harcano 12 fan controller. I hate it, looks nice, but the fans never run at full speeds, and every time you turn off your system, it doesn't keep your settings.
I have heard very good things about the vantec fan controller, and it isn't that expensive. Personally, I don't think you need one. The first thing I would do is to get a good heatsink and fan combo, a thermalright and a panaflo would probably be as good as any. You can run the panaflo off your mobo. I don't think the noise would be too noticeable if you leave the case cover on. I also think that if you are worried about air flow, try one of the ducting mods i linked to, that will keep you from cutting your case and will bring cool air onto your CPU. This total should cost you around $50, maybe a bit more with shipping.
