Soldato
The 3 fans have 3 pins M/B heads, but you get a molex adaptor for all 3 (which is what I used). And they are directly wired into the High / low switches.
As for the 2 PCi-E cables being routed behide the M/B. a) There is not a lot of space round the back for cables. b) i think it will block (not a lot) the fan air flow.
