I wrote it just now, that we have of course measured both PS5 also before disassembling. The non-contact infrared measurement of the outer surfaces is of course the best solution. The respective measuring points were configured with the correct emissivity, since they are different surfaces. What we see in the images that follow now is a slightly different heat signature, though the differences of hotter or cooler roughly balance each other out.
Of course, these thermal images are only one small facet, because the surface temperature still says nothing about the true temperatures inside and the accompanying phenomena such as fan speed and operating noise. We will also determine the underlying power consumption as the basis for the heat development in a moment. But it is already apparent here after the first weighting of the measured values that one cannot speak sweepingly of “5 degrees more” for the new PS5. On the left as usual the new PS5, on the right the old one:
