That's great.
I'm running 4.6GHz at 1.45v +/- with a thermal margin of 20C, UNB at 2500MHz-1.25v, with some GSkill 2400MHz Cas10. Occasionally, the margin will drop to 18-19C.
Trinity/Richland chips are "volt-leaky" and love the juice. Even more so with the CUs disabled. If you think you have a temp issue, simply place your finger on the sink. If you pull back a smoking nub, you might have a problem
I'll bet you don't, especially if you are running stock.
The "volts & heat" from the chips come from the on-board graphics engine. The CPU cores only take up 130mm2 or so on a 256mm2 chip and are quite efficient. If the graphics engine on the die is not under load they become even more so.
If LTF is using a discreet card, that's why his thermal margin never drops below 30C because the CUs never max their volt load.
