Yes, for a mainboard those temps are not normal. Well at least not good. Mine go never above 50. The highest I have seen was 40-42°C with overclock and a discrete GPU. But of course my case is ventilated not too bad.
You might want to check your case and your fan positions. Too many or too less fans and wrong directions are bad for cool temps. Also a tidy and organized case can get you some benefit.
I recently put my cooler on again, cleaned my case and did some pretty good cable management. My temps improved quite a bit.
