Ok guys so I purchsed a Phenom II x3 720. I unlocked the 4th core and it runs stable(running prime95). Since I'm using the stock cooler I tried a simple overclock to 3.0 ghz with a 1.4 vcore. I run prime95 and after 30 seconds to a minute my computer turns off. Does this mean its getting too hot? Also since AAC is on my temp reads 0 C but I touch the heatsink and its not hot at all.
