Sorry for the slew of n00b questions lately, I'm kinda getting back into this whole overclocking/cooling lark after years of just using my PC as, well, a PC 
I notice programs such as speedfan show up a "CPU" temp (which correlates with the BIOS CPU temp) as well as the two core temps. Which ones should I concentrate on more? The two core temps?
Also, what's the max safe temp (of whichever reading above I should pay attention to) of my C2D E6420 I should be watching out for, before it starts to melt?
Cheers
