Start with Arrhenius.. 10degree rise halves the life.

Actually, there's a huge amount of information out there on semiconductor failure and life effects.  It's just not distilled down to a "for part #, here's what happens", because it depends on a lot of things.

Issue is not the temp spec of current cpus, problem is that it is hard to get relevant information. I haven't found any that states that the failure rate in year 5 should be significantly higher if you operate the cpu at 65 C instead of 55 C. I'm just saying this kind of information would be valuable (and I would be glad to find it).
