Well, since it is the first time you're running it, it may be possible that the core temps are being displayed on differently labeled diodes. For example, I run a Pentium D 2.8Ghz dual core processor (overclocked to 3.4 Ghz), the processor temps on the diode are incorrect, both reading 0 degrees, this is because my temps for the processor is located under the diode named remote and temp 1.
