My pump is wired in the cpu fan header and the radiator fans are connected to NZXT smart device..
I did close everything on background including CPUz, CAM and temps are down to 38c, but voltage is still in 1.4v.
Not sure if nVidia geforce xp and control panel has a effect here.
ftr, I haven't applied any overclocks yet, this is all outside the box configs.
Will give this a try later.
