Ah ok, thanks Shumway. I found that I can get a 3 pin fan extension cable, but I can't find any cold cathode ones, and I don't really want to bother getting one from the US. I think I may just mod my case a little. I have a free 5.25" drive bay, and I might cut some little holes in it and stick the cathode switches in them there, and stich the inverters in the bay. Seeing as I wil have 3 inverters soon, it will probably be a better idea than having them all at the back.
Another couple questions for you though, if you lower the speed of a 120mm led fan with a fan controller, will that also dim the fan? And, if I have x2 blue CCs, and put x2 UV CCs in my case for my soon to be UV sleeved cables, will my cables still glow? Or will the blue light erase the effect of the UV? Or is the UV light quite strong?
