There is no question unclewebbs E6400 tjmax is 90C based on 85C IHS at DTS=0. Randomizer, I wonder if your cpu runs that hot, or if it is proof that intel has used different tjmaxes. Would be interesting to IR that one. If your tjmax is lower, that would explain intel's 65nm tjmax releases (the one before unclewebb and coolest complained and the one after) and perhaps explain why some quads have significantly different temps even at high range.
