oh the endless debate on the best air cooler will rage on forever it seems. is this a viable solution for everyone, considering its size? of course not. Is the copper true realistic for everyone considering its size? of course not.
but no one is asking which is realistic for every user out there under the sun. YMMV.
the question is which is BEST.
I believe poparamiro's numbers, he is a established HS tester and has great methodology. and his numbers say this is the best out there. He did a writeup recently testing a VAST number of heatsinks. others testers are already agreeing with it as well.
maybe there needs to be size classes for the heatsinks? like heavy weights and lightweights? like boxing so people dont always have that "yeah, BUT...." to whine about.
