yeah, i gotta admit it is a bit quieter, but without the second fan, my cpu temp is about 5 degrees higher. and you're not getting the extra 55 watts the 330 gives you. IMHO, stick with a good enermax. If noise is a concern, you're better off using the best supply and sticking your comp in a closet or better yet another enclosure like a cardboard box. No joke, i use one and love it. I mostly do harddisk recording and editing so it's a godsend. good luck.
