Looking at your SS your package temp hit a high of 66c. We generally want to keep that under 62c. If it were mine I'd say that's a good overclock for 24/7 use. If you wanted to keep playing you could start dropping your CPUv 1 bump at a time and re-run prime to see if it will pass. If you can get the same OC at lower volts you might extend the life of that CPU a little and lower the temps at the same time.
