first, its the 2.53 model with, previous line. 1. temp , can reach even 80c while in idle! 2. temp is about 60c while fans in max (about 6200rpm) and while idle. 3. can reach easily to 90c while working hard (sometimes even more then 100c) I'm looking to buy new fans, but I don't want the stock, but perhaps something better with lower power needs but with better cooling. If i must, i'll but the stock... but they really made problems from the first day. so...where to buy?
