very true bobby, a 40mm fan shouldnt hurt it, but once you get into case fans its just not worth it. i dont like to risk it at all and i have enough connections on my fan controller so i just use it. on channel 1 i have the cpu fan and NB fan, channel 2 has my 3 intakes, channel 3 has my exhaustes and 4 will have my PSU fans (antec true series lower the voltage on the fans so they run quiet, i want cool not quiet so im gona run the fan wires out with all the other fans and wire them to my fan controller.
