Manual Mode uses levels going from Level 1 to Level 10 max for the CPU headers. It should be no problem running the pump from the motherboard alone, I still wanted to get the controller to slow down the 4 fans on the rad, I could only slow down 2 of them, the other 2 were a problem. And besides, them running at 100% 24/7 is kind of annoying along with the pump.
But seeing as I know the board for sure can handle the pump, if I can have variable software control, I'd feel safer knowing that I'm not going to burn out an expensive fan controller. I've already had it happen to me with a 48w Delta fan and my poor Zalman has a burnt header, don't wanna do that again, lol.
