Whilst at first glance it would appear things can only get cooler, multiple cores means things are only going to get hotter under the collar for CPU manufacturers.
Adding cores doesn't change the amount of heat over a given area. More cores may mean more heat, but it also means more area.

Agreed TDP will go up if you simply throw more cores on there, but my argument I was responding too was heat over a given area, not TDP. TDP is fine to go up, as long as size it going up was well. More size means a larger heatsink. If a cpu were 1 meter by 1 meter in size, the heatsink could be 5 meters x 5 meters in size, it still would not likely have a problem cooling the CPU (although it would need a massive fan) .

Except that the IHS remains the same size, so it's still the same area.

If anything the temperature is staying the same

Speed increases whilst voltage and NM decreases, resulting in an overall similar temperature whilst giving increased performance
