The reported temperature (Tctl) is "on its own scale aligned to the processors cooling requirements. Therefore Tctl does not represent a temperature which could be measured on the die or the case of the processor. Instead, it specifies the processor temperature relative to the maximum operating temperature, Tctl_max." (Quoted from the AMD Family 12h Processor BKDG.) You have a FM1 socket processor. Tctl_max is 70 in your case. So the reported temperature of 9.8 is far below that maximum operating temperature.
