When you type direct Cu II you can't capitalize the u because then it goes from being copper to carbon uranium II cooler and an ion can't be multivalent so the II doesn't make sense. And I doubt that asus uses exclusively copper II for their coolers. This post may seen anal but IUPAC disagrees and standard nomenclature is important.
