How to read Tcontrol from Yorkfield

[cmm-rd-bios2]

Now ,i can read Tcontrol by Maximum Power Program ,Tcontrol = -22 degree.But I don't how to read it in my tool?

If read CPU temperature by die, we can get Tcontrol as follow:

MOV ECX, 0x1A2

RDMSR

then read AH,Tcontrol = AH + 0x32

But now CPU support PECI , how to read Tcontrol ?
