ASUS use some compensation to more accurately reflect the chip temp while no temp sensor can give you the true estimate anyway. I have a A7V133 too, i think whatever soft you use, it will just read the value from the BIOS which is already compensated. Some softs do enable a manual offset value(you can minus as many degrees as you want) but so what?
Bottomline, if PC probe gives you under 57 celsius, your CPU should be fine,
