Heat is a huge problem?

Heat radiation elements must be designed as part of the structure?

Sophie Wilson has famously said how easy it is for active silicon to get hotter than a nuclear reactor.

The center of a fuel rod in a PWR reaches more than 1000 C.

Perhaps Wilson was talking about the thermal power/area of chips vs. the surface of fuel rods. I believe the former can exceed the latter.

Poorly designed or managed chips can reach the point that hot spots in the silicon literally melt, which happens at ~1400C. Thermodynamics sitting on an insulator (relative to the metal portions of the chip at least) on very small scales is very weird and can reach wild spot temps.

That's why chip thermals is its own whole subfield of physical design.
