Yeah well, you need to do stress test for recommended 30 minutes, I usually do like 5-6hours to check for highest temp, crashes etc. So if you overclock to 5ghz at 1.39v and no crashes at 40C that is pretty good actually, to high cpu voltage I might say, try decreases it a bit. Again 4.7-4.8ghz is good enough, no reason to overstress it.
