Like I said before I'd go by the bios setting.
Downoad OCCT, you can configue voltages and temps in that as well. Open up some of your other temp progs and run OCCT, if your temps aren't flying up over 70C then your ok, under 60C would be nice. OCCT 1 hr test is also good for testing OC's.
Hope this helps.
