[lm-sensors] w83627dhg and coretemp temperature mismatch?

Hello everybody,
I have a Asus P5B-VM and after some fiddling and upgrading to 2.6.22, I
now have all thermal sensors (w83627dhg and coretemp) up and running.
However, I noticed that the readings from coretemp are always
significantly lower than those from the Winbond chip - an example:
w83627dhg-isa-0290
Adapter: ISA adapter
Vcore: +1.29 V (min = +0.85 V, max = +1.60 V)
+12V: +12.30 V (min = +10.19 V, max = +13.46 V)
+3.3V: +3.23 V (min = +2.98 V, max = +3.63 V)
+5.0V: +4.99 V (min = +4.51 V, max = +5.50 V)
Sys Temp: +51°C (high = +16°C, hyst = +90°C)
CPU Temp: +50.0°C (high = +80.0°C, hyst = +75.0°C)
coretemp-isa-0000
Adapter: ISA adapter
temp1: +43°C (high = +85°C)
coretemp-isa-0001
Adapter: ISA adapter
temp1: +42°C (high = +85°C)
As I have a passively-cooled CPU, I am a bit nervous about temperatures,
so I'm curious if somebody can explain the difference (and which one is
closer to reality ;-).
Thanks, Yours, Florian
