all things being equal (same HSF and case, same fan speeds, probably quite cramped with the same mobo, gpu, etc, etc.)
Would an e4300 be likely to run cooler/as-hot/hotter when compared to, say, an e6600, or an e2160, assuming both chips are running at the same GHz? Perhaps if someone's spotted the temperature stats in a review somewhere?
I'm leaning towards a uATX build and fancy keeping the noise down as much as is possible. With the coming price cuts and new 6x50 cpus the price : performance advantage (assuming an overclock) of the lower end C2D chips will decreasing a bit, so if it'd mean a significantly cooler-running cpu I'd rather go for the better-at-stock processors...
