Hello,
It gets hot. The processor is an automotive processor (supposedly). Anyway, I suggest a fan or fans (plural).
I know it is a big deal w/ this being a new board but I think all the kinks have not been addressed by the .org for now. Anyway, to stay on the safe side of things, fans.

P.S. W/ a tiny USB fan, my sink and board are now cool. I feel your warranted call. I was afraid at first for the processor b/c of its heat dissipation or lack thereof. Fans.
