Temperatures on AMD 720 BE

I unpacked my desktop after a couple of weeks trip. It fired up normally but crashed after 10 minutes or so. Since I had a laptop that was overheating, I thought maybe this desktop had heat problems also. All of the temperature sensing programs show that the CPU is running at 60-80 degrees C, and this with just Rome Total War running. All of the fans seem to be working normally. I've removed the side panels of my case and directed a house fan at the CPU and it was still running 60-70C.

Is this running too hot and if so what should I do to troubleshoot the situation?
