Those Temps are normal if you are using the stock cooler on it. Also you should take in consideration the ambient temperature zone where you live. An ex. My CPU is a corei7 920 overclocked @3.6Ghz, cooled by an Hyper 212+. And temps raises up to 79C° running prime95 and the ambient temp in sommer where I do live are at 29°C sometimes 30°, and when ambient temps go down to 19° my cpu @ full load with same frequencies goes up to 68°. so as I saw this I can tell you, you are fine.
