Banana Pi M3 running 8 threads cpuburn-a7 outside of an enclosure with a $0.5 heatsink applied. Due to thermal throttling settings in Allwinner's 3.4.39 kernel (same behaviour like on the H3) tempterature stays a bit above 80° while cpufreq jumps between 1008 and 1200 MHz and due to dvfs settings therefore adjusting the Vcore voltage between 840mV and 920mV.
