Sydo, just ignore idle temperatures, the temperature sensors on these AMD chips are not accurate below 40c when not under load. What is important is your temps under load. When you overclocked in the screen shot above did you stress test it with prime 95?
EDIT: your temps are fine, recommended temps are below 70 on the cpu and 62 on the package. You can keep pushing further, just raise the multiplier and test, if it fails ie loses a worker, bsod or freeze, add voltage.
