i think that even tho the copper heatsinks are not as good at convection as aluminum fins, they seem to make up for it with the high conducive qualities. logically they souldent be as good as something aluminum with a copper inlay, and ive been skeptical about the all copper heatsinks (as ive been skeptical with this orb craze). but ive heard lots of good regarding the copper heatsinks.. i guess we should wait for some more reviews to pop up, but like ive said.. ive heard good, so maby the tradeoff between good conduction\not as good convection isint as bad as you\I think.

(hope i got the conduction and convection terms right, heh)
[edit] after reading that review, that thing sounds real crappy, guess what ive heard dosent mean jack =P[/edit]
