Thank you. Might do that. Now when not utilizing the box it goes to sleep / shuts off. I am able to turn it on and via CEC it turns on the TV which works for me.
Last time I checked after a few hours saw this:
CoreELEC:~ # sensors
soc_thermal-virtual-0
Adapter: Virtual device
temp1: +69.4°C (crit = +105.0°C)
ddr_thermal-virtual-0
Adapter: Virtual device
temp1: +71.9°C (crit = +105.0°C)
around 10 °C of passive cooling would suit me fine. Did you just put a heat sink on the CPU? Do you have any pictures? I have a second one not utilized yet and can take this second one apart before putting it in to production.
