To Martin and the other folks,

Thanks Martin for the excellent work and efforts. I just could not find in the stickies or in this thread anything about the difference between using 120X25 and 120X 38 on radiators. As I am about to build my system, and thanks to your charts I narrowed down my choice, but I don't know which to use, 25mm or 38mm fans?and what effect would each have on the flow? I am probably going for a Feser monsta, to cool 2 blocks ( cpu+gpu) and another seperate loop for nb, sb and other chips.
