hm..i'm not really up to what is with the good idle temp. But that sounds kinda hot to me. You need more fans for sure tho. And are you sure your mobo is unlocked? Dude are you saying from a 3 ghz to 4-7? maybe if kept your comp in a freezer. But not otherwise. i doubt it will even run stable over 3.4
I was replying to you to say that 55C isn't that hot. the only way to get 100Cis when you misinstall the heatsink and fan or without installiing one at all
