These are all PC Health informations I could find in the BIOS:

CPU Temp = 49°C
CPUFAN = 1692 RPM
Vcore = 1.232V
3VCC = 3.360V
VTT 1.1V = 1.120V
PCH Voltage = 1.096V
IGD Voltage = toggles between 1.176V and 1.184V
VSB = 3.280V
VBAT = 3.344V

The voltages are rather hard to match aren't they?

Hope this helps.

Tobias
