It's electronics and thermodynamics actually. People tend to anthropomorphize electronics, but Tcase of up to about 72C is not an issue at all for a CPU (official Tjunction max is 100-105C - that's the temperature of the chip inside the case). The spec states that the CPU will work fine as long as this temperature is not exceeded. In electronics the spec is the word of god, and if it says so, the chip is safe to operate at that temperature for its rated lifetime. Consider as well that cooling systems require temperature gradient in order to work, the higher the temperature gradient, the less air you need to move to dissipate the heat. Apple has been doing very careful thermal management for well over a decade and a half now. They don't excessively cool their hardware. This is made possible by vertical integration: they can rely on the readings of their temperature sensors (unlike say a PC enthusiast, where those readings can be wildly off).
