    Insufficient static dissipation

    The dissipation in passive mode is clearly insufficient, with a AMD Ryzen 5 5600 processor (TDP 65w, i.e. half the specs of the A46) limited to 2.4Ghz and loaded at 15/20% in parmanence the cpu does not reach a temperature stability point, I stopped at 85°C and it continued to rise.
    Looking for the reason ... when you look at the specs of the A46 there are curves of Rth / CFM / Stress which means that it is not designed to operate passively. Too bad ........
