The problem with IB is that the small amount of heat that the chip produces (compared to something like nehalem, gulftown, SB-E or even SB) has to be dissipated from a die much smaller than usual (also 3d transistors might have something to do with this as well) and as such it's harder to do. This is why the temps are higher and why just adding say more radiators with a watercooling loop doesn't help with IB.
What IB wants is sub ambient cooling. Phase for example should make IB shine. Haven't really seen any tests though.
Yeah I kind of see what you were getting at. I'm a chemical engineer so tend to take these things very literally, expecially with regards to heat transfer!
Although the IB die may be smaller, you are assuming that the heat transfer resistance due to the thermal conductivity of the metals used has a significant effect of the rate of heat transfer.
This would not be the case at all, the heat duty of your pc cooling hardware is always mostly limited by the aircooling part of the heat transfer process, whether that be on a watercooling radiator or on a traditional air cooling set up.
I expect that a decent watercooling set up would have little trouble keeping the temps down on IB.
Although I'm going to wait for a revision...
