The H60 is perfect for more than just "stock or near stock" cooling. Clearly as per the OP's situation, it's fine for 1.39v and 4.7ghz. Temps are perfectly fine. Still, if it were me, i would drop back to 4.5 or 4.6 and get that voltage down below 1.35v for safety, and because those speeds are beyond all that's necessary and very strong gaming performance.
