Run a load on your rig at default freqs and voltages and watch your temps. I would recommend something like Prime95 to stress your CPU and furmark to stress your GPU(s). Pay close attention to your NB temps with this motherboard to make sure that you have good contact between it and the heat sink....if it gets too hot then you should remove the heatsink and replace the TIM. Do a couple of test fits to make sure you are getting proper contact. Some had to take further action still and shave the stand-offs down a bit to get the proper contact.
Bottom line.....on air don't go above 55C in your stress testing and try not to go above 1.5v for a 24/7 OC on your CPU.
