mine (Friendlyarm/allwinner/a64)is too cold to believe:

dev.aw_thermal.0.gpu2: 17C
dev.aw_thermal.0.gpu1: 17C
dev.aw_thermal.0.cpu: 15C
dev.aw_thermal.0.%parent: simplebus0
dev.aw_thermal.0.%pnpinfo: name=thermal_sensor at 1c25000 compat=allwinner,sun50i-a64-ths
dev.aw_thermal.0.%location: 
dev.aw_thermal.0.%driver: aw_thermal
dev.aw_thermal.0.%desc: Allwinner Thermal Sensor Controller
dev.aw_thermal.%parent:

and it’s summer here.
