the temps in asus probe and other programs that base temps off the bios are ridiculously high, for example i thought my cpu was running at 65 degrees on load, which is above amd specification. I downloaded core temp which shows you the actual temps, and now i idle @ 42 and under load is in the low 50s, that is after OC to 3.7.... seems like I have 12 more degrees to mess with, so it is likely possible on stock cooler especially if you have automatic voltage in ur bios.
