I'm curious how they claimed that the cooling solution is over-designed because they were only able to achieve 80% of the spec'd power target (most likely TDP since people stopped using max power in the 00's). There are a number of factors that go into spec'ing this value, typically quite a few test vectors to determine typical workloads and high-power targeted workloads. A mistake in power budget of 20% is gigantic and would have significant impact on sorting die. Now maybe Apple doesn't care about this because they aren't a silicon vendor, but that budget comes out of battery life and cooling solution space. My point is, I find it highly unlikely Apple overstated their power target by 20% given how much money it would have saved them. But maybe they did?
