It wouldn't surprise me if the 2.8Ghz CPU has to have the fans ramped up a bit more, REGARDLESS of which 2.53GHz chip is in it by default.
Though power management stuff may negate that to a large extent. IMO the upgrade isn't worth the price really, although it's not a total rip off either (more just that Intel charges a lot for the very top bin CPUs).
