TDP went up. TECs are extremely inefficient, and have limits on how much heat they can pump in a given area anyway. a 10W chip, you can maybe get away with, and it might be a meaningful improvement compared to the other cooling tech available at the time, if you don't mind the power usage. with a 100W chip, you have no chance. (You can see a demo here where LTT try it, and they, after dumping 500W into the cooler, can get the CPU to a vaguely reasonable temperature, until they actually load it up: https://www.youtube.com/watch?v=sWrqyQWfhrs https://www.youtube.com/watch?v=sWrqyQWfhrs)
