You mean the warnings on clocks (starting from runtime PM and FIMC)? I hit them also on Trats2.

No fan so cooling is done only through CPU frequencies. The fan probably works on default setting from bootloader or default register values. The stock Odroid U3 has only passive cooler. Probably support for fan could be added... If you would like to take care of it, go for it! :) Best regards, Krzysztof
