well i have a X6800 not OC and the stock fan cant keep it cool, idles at 40c with all fans at 100%, but skyrockets into the 60c when under 25% load :/ i was wondering which of these coolers would keep it cool, OCED or not. and also whats a safe DIE TEMP for my cpu to reach b4 i should get worried? my core temps stay in the 40s but my die temp is high.....? Thanks.
