a plain HP-HSF, would proly be more effective, less complex, and would probably move more heat too... at the end of the day it is still about surface area... big heater-cores are here to stay... and the bigger the better...
they have nice sounding technology, but their graphs are not keeping true to their technology... with nice shit like that, I want them to at least be on par with what I'm getting with my Shade-tree technology.
None the less, they look good... and in today's MHz=everything world, looks will move 90% of all that is going get moved. it is only that 10% that truly do their homework, before they buy, that are going to be reaping the benefits.
