Interested to see the numbers they get.
FWIW, It's also not just a matter of the surface area of the part being cooled. Things like load, thermal capacity and thermal conductivity are also critical components, so it's difficult to make an apples to apples comparison between two different systems. For example, the CPU die/heatsink being discussed above is certainly much smaller than a compressor head, but it also has the ability to reach critically hot temperatures almost instantly during operation, whereas this is not the case for a compressor head; the ramp-up time for a compressor head to reach a critical temperature would take much longer in normal operation, giving the cooling system an advantage. Similarly, cooling a CPU die is arguably less efficient than cooling a compressor head made entirely of metal, even with the fancy heat spreaders that CPUs have these days, again giving the cooling system an advantage on the compressor head.
