You are in the gray zone....
It is a bit hot, but not so hot that you can say that there is an issue for certain.
I like to see the CPU <70 under max load.
I would check your chassis fans (since the screen shot is not showing any)
Try running a test with the case open and see if things are cooler. If so , you need a fan to get the heat out of the chassis
Check the CPU heatsink instillation. Make sure all 4 pins are snapped into the mother board
Make sure nothing like cables is blocking the air flow.
Last resort might be a after market heatsink (parsec has a number of postings listing some good ones.)
I would try to get the temp down if you can since if your hitting the thermal max, the CPU will throttle and you loose performance.
