The duct on the 3000b is excellent, the only thing I dont care for is that it is non-moveable. If you could position the duct directly over the CPU center for all mb's, I can't think of a case that would cool better. The duct lined up pretty well with my IC7 mb, but not great with my new DFI Ultra-D. I am going to do some modding to get the duct positioned dead center. When the duct was extended down to my Zalman 7000 on the IC7, the CPU temp was drastically reduced, and it only makes common sense that it would be....
