AND_YOU_ARE - In response to your question yes I did use splitters. The 80mms in the front were all 3pin connectors and my fan controller has 3pin connecters as it's power source. You plug 1 4pin molex connector into the Fan Controller and it powers the rest through the 3pin. You can get any kind of splitter, extensions or convertors at www.svc.com
to connect 3 3pin fans together requires using 2 3pin Y-Splitters. Hook two fans up on one 3pin Y-Splitter..then hook the two fans on one pin of the 2nd y-splitter and the 3rd fan on the 2nd pin on the y-splitter followed by a 3pin extension and you have 3 fans all controlled by one line! In the case of my rear stacked fans I simply spliced the wires together so they run off the same power line...I only did this because the 2nd fan I used to stack on had a 2pin connection from an old Intel machine.
My Fan Controller is rated at 20watts per channel while most say 15-18 and I don't like the idea of 15 OR 18...I'd rather take my chances with a company that says 'YEAH 20 watts per channel straight up!' so thats why i went with them and knew it could handle the Tornado and multiple fans hooked to it.
