According to this chart: http://www.frostytech.com/articleview.cfm?articleid=2655&page=4 CM Hyper 212 evo is 6.4 degrees cooler than Noctua NH-C12P (with high fan speed). So here's the question... Noctua costs twice as much as Hyper 212 and is to my understanding considered to be a superior heatsink; is there any reason that I am not aware of why I should spend more and get less?
