Unlocked 4th core, coretemp readings are normal?

[quicksilvr]

Hey everyone,
I recently unlocked the 4th core on my AMD athlon II x3 450. After unlocking it, i booted in and everything seems to be working fine. I'm going to run a stress test on it later, but my question is with coretemp. After running the program, it seems that the unlocking of the core only increased the heat output by a little bit. After doing some research, i found out that this might be inaccurate. Is there a better way of checking the cores' temperatures?

Thanks!

You can check it against HWMonitor.
