Oxide's blogs talk about cooling _a lot_, apparently their stack runs very cool b/c they've reorganized the whole thing around efficiency, and written all the firmware to support that goal.
Skeptical of that. There's only so much you can do against the physics of moving electrons around at high speeds... "Bigger Fans" and "compute density" doesn't change that
you're right that there are efficiency limits, but not once in my career have I ever seen anyone even attempt to write their code so that it is efficient to run, outside of gaming.
