Temperature Margins

Total noob here. AMD A10 6800k APU. Stock clock.

Whilst rendering, I had a look at my temps on AMD's Overdrive software. My CPU usage is nearly 100% as I'm rendering and I have a temperature margin of around 12 degrees C.

Talk to me. Is this bad/good/terrible? Is there room for OC? Is it finally time for me to order a 212 Evo?

While i'm no sure what you mean by margin of 12 degrees C. do you mean that the temperature of your CPU goes up by twelve degrees? 

My question would be while rendering what is the max temperature that your CPU reaches? and what is the idle temp?

 wtf margins? how bout you tell us the god damn temp
