CPU temp: 54°C CPU temp: 54°C
Without heatsink it is normal, I think, but with previous configuration I never come over 50° so I try to reach this.
What range of temperature do you have ? If I use a closed enclosure, temperature increases to 80° and I stop the board.
With h3consumption and a 3.4.113-sun8i I can keep under 50° reducing number of cpu and ddr freq, if I use a closed enclosure, so that's what I try to have.
