What cooler do you have now for the i7 950?
As far as temperatures go:
1. Thermal tolerances are different from one microarchitecture to another. 80C may be too hot for one architecture but normal for another. Generally newer architectures like Haswell are designed to run a bit hotter.
2. You should focus more on thermal emission and dissipation than temperature. As temperature will be determined by both how much cooling you have and how high you decide to OC the chip. As well as a number of other more minor factors.
3. Haswell is a bit less efficient at dissipating heat because of the use of TIM instead of fluxless solder between the IHS and die. However its stock TDP is MUCH lower (83 W vs. 130 W) and that's at a higher clock rate (3.5 GHz vs. 3.0 GHz). So 83 watts at 3.5GHz vs. 130 watts at 3.0 GHz......yeah. And keep in mind to reach a 4.2GHz OC is a 40% OC on the i7 950 but only a 20% OC on the i7 4770K. The former will require a significant voltage increase while the latter will not. The result? Haswell should run much cooler with the same 4.2GHz overclock even with the TIM.
