... about the poor efficiency of the cooling system on N2 (costs do not meet the requirements of the result), referring to the fact that at that time I had no sample of N2 (by the way, actual tests have confirmed the correctness of my calculations)....
I must correct you (as others did many times) ... I'm no fanboy but rather manufacturer & SOC agnostic; always looking for the hardware which suits my needs best. So: just an ordinary user and I still have to say that the N2 cooling / temperature curve is superior to anything else I saw ...
Comparison; both more or less in some sort of idle mode:
LibreELEC (official): 8.90.015 (RK3399.arm)
21:31:56 up 30 min, load average: 1.34, 1.57, 1.41
CoreELEC (official): nightly_20190607 (Amlogic-ng.arm)
21:41:50 up 29 min, load average: 2.28, 2.04, 1.73
that's all I have to say
