Then I appologise fully and concur, to some extent. The stock speed isnt 3.9, it will boost to that if only one or two cores are in use (If there is thermal headroom). The poster wasnt clear , he said he was running at 3.9. My misunderstanding. I do, however, stand by what I said. Intel are no longer specking there chips to last 10 years, as the redundancy factor of more demanding software has ended for now. So pc's lasting ten years is bad news.Intel will only warrent that chip for 3 yrs. The statement ' Good for Ivy Bridge' says quite a lot about sales psychi. They say its good for 105, so you say thats fine then.
I dont know of any standard electronics component that is rated at that temp for long term use. Poster also said he had a freezer i3 cooler, can only assume thats aftermarket, not an i3 cooler, which is probably the same as the quads. In short, believe the hype if you want, but I think mid 60's is hot enough for a 300$ electronics component..
