I have a 3930K on an Asus P9X79 PRO, under a Corsair H80, and it is 100% stable at 4.8Ghz. It get's pretty hot (high 80's to low 90's c) but that is in spec. I fold on it 24/7 in the winter when electricity is cheaper, and it is very stable and very fast. You do have to get the voltages into the 1.4v arena though. The CPU could probably do 5Ghz if I had better cooling. That CPU is just a BEAST!
The temps may be within specs but I can pretty much guarantee your chip will degrade a lot faster running 24/7 at those temps. JMHO
