Will have a look at it again, ran into a wall last time, but I also am not a fan of thermal limits and pushing the odroid further and further these days.
Well, I switched to a minipc so the odroid goes on sale. It was a fun ride.
It would be really interesting to know if someone has a solution to this problem. At the moment my fan is always on even if the Processor temperature is at 22C (degrees Celsius) = 71.6F.
