You can monitor in bios, or use Everest/CPU-Z/any number of system monitoring tools in Windows. I'd say 40c is max at stock for your processor, probably even less. If things aren't seated properly you'll see it rise to 70c+...it can take that heat, but not for too long. Be careful when attaching the board to the backplate, too much pressure on the wrong areas can crack it. Try to make your wiring as tidy as possible, especially around the cpu fan. You shouldn't have to touch the bios in the beginning unless you have trouble booting up or something isn't installed correctly. But those things are pretty foolproof these days...if you screw something up it'll just reset.
