The readings on this motherboard is iconrrect. 
My cores real temperatura was 50°C and the voltages are totally incorrect. 
For example, the current Vcore is 1.35v and not 2.17v 
Also... The motherboard is shown as unknown and sometimes e get everything 0°C on the CPU cores. (when i don't use PC Probe II)
