I'm not certain that 2 way fans is really a plus because from my experience it increased the noise by a fair margin but not really lowers temps but it may depend on the cooler. And I think that "caged" fan containment around the actual cooler will hinder airflow and thus decrase cooling performace.

It's all about airflow and keeping the air moving over the fins of the heatsink. If air isn't moving, heat transfer is occurring at a slower pace, which could limit performance. (hah, maybe a couple degrees difference, but whatever)
