    Yes it is, the seonsors on AMD indicate a 15-20C lower temperature than it is.
    Have you seen an Thuban working at 75-80C? No because than it already entered in throttle.
    It is the reverse.

    A big surface has an easier time transmitting all the energy and thus being cooler.
    Well BD at same surface at Thuban will have much more tranzistors in it.
    What you say works in a closed case for a short time, but in a long time the air inside is getting hotter.
    What i'm saying is that BD will need a strong cooler like Noctua DH-14.
