Спасибо что откликнулись. каталог /sys/class/drm/card0/device/hwmon у меня отсутствует всё делал как описано в статье. температуру меряю по показателям процессора, он у меня на одной медной шине с видеокартой. при включении echo "battery" > /sys/class/drm/card0/device/power_dpm_state температура падает на 1 градус.
