Thanks Jonnie. I'm not totally convinced that TIM paste will be a permanent feature really... One might actually suspect that retail units will be soldered, and what we've found and explained in this article is more meaningful for the preliminary results we're seeing in most of the reviews and forums about Ivy getting hot when overclocked.
There are some exceptions, despite most people raising questions about the heat when overclocked, like the computershopper overclocking results:

They didn't perceive the temperature issues reported in most articles with their sample. Their test was rather quick at 10 minutes then a temp reading, but I suppose it could be an indication that not all these chips are hot. Anxious also to see if Intel can add better insight than what we have to work off of currently.
