Plagiarism? ARKUA 6228 And 7528
If you didn't know better, you wouldn't be able to tell the aluminum profiles of the two Arkuas from Thermosonic's V60-4210. But that's no surprise, because Arkua has become the exclusive distributor for Thermosonic's cooler.
If you think the Arkua 6228 is just a rewired Thermosonic V60-4210, you've got another think coming. The aluminum profile may be identical, but the 6628 has a copper core and a much more powerful (and louder) fan. Both of these differences help jack up its cooling capacity enormously.
Its cooling capabilities would certainly be better if the copper core weren't smack dab in the middle: it only covers part of the die.
The Arcura 6228 is an ideal overclocking machine, unlike its blood relative. Even an Athlon XP 2200+ feels nice and breezy under this cooler.
