  More than just your cpu, gpu, and psu generate heat in a desktop, but they’re the only units that normally have giant heat sinks with dedicated fans for cooling them.

  If there was a hole in the center, but the main producer of heat was still covered, that’d be a pretty bad design for heat dissipation.

    a desktop isn’t a flat phone with no airflow… the whole phone is the heatsink.

      I don’t think we’re really getting anywhere with this, but that’s kinda my point.

      Take a large pan and set it off-center on the smallest burner on your stove top. The entire pan will get warm, yes, but the part directly over the flame is going to get the hottest.

      The cpu is the flame, the pan is the phone. If you have to wrap the pan in some sort of protective coat, but want to effectively dissipate heat with the smallest hole possible, the smartest design would be to place the opening over the source of the heat, not the center of heat sink.

      If the cpu is in the top corner of the phone, the top corner of the phone is going to get significantly warmer than the rest of the phone (in terms of thermal dissipation). Putting a vent hole in the center where there’s less heat while having the warm part covered makes no sense.

        if you heat up a pan does the whole pan get hot? or just right under the spot with the flame?
        is the cpu the only part of the phone generating heat? or does the battery and everything else get hot?
        here’s a thermal image:

        you’re right, we’re not getting anywhere just imagining how it should work… a thermal image does get us somewhere though
