I used a slightly lowered value from the BSP code. 110 seemed like a lot for the critical temp. So I rounded it off to 100°C.
https://megous.com/git/linux/tree/drivers/thermal/sunxi-temperature.c?h=a83t-3.4-bsp-tbs-a711#n1139
H3 lists the same recommended ambient temperature range as A83T. -20 to 70 °C.
regards, o.
