You cant' do this for several reasons:
You need ambient temp, cpu cooling, "temp reading" software, Motherboard, MOtherboard Bios, etc...
Another reason socket-a Temps are screwy. A lot of MSI boards read a lot lower than actual core temp. A7V class boards read a lot higher than MSI boards, and you often get posts about why their temps are sooo much hihger than the 30C range temps they are seeing. A thread of this nature merely adds to that confusion.
