Temps and voltage are fine. If everything is stable, no worries. Generally 80C long term for CPUs is about the max you would want to be. All modern CPUs will throttle if things get to hot. Voltage looks great. 1.35v is generally the highest recommended for long term CPU health, though nobody can say 100%. AMD themselves mention this number though. I'm running my 1700 @ 3.85 using 1.38v under load using a DMM. Your LLC should be fine. I'm using my Crosshair VI Hero on AUTO for LLC. It keeps the voltage at about .01v above my 1.37v setting under load.
