Hi Jean---

Unloaded both. Dump for isadump 0x295 0x296:

Interesting about i2cdump 1 0x2d b:

dean at linux:~/Desktop$ sudo i2cdump 1 0x2d b
sudo: i2cdump: command not found


I got from BIOS:
CPU temp=40c
board temp=35c

So I don't know where the 98c is coming from....
After reloading the w83627ehf I get:

AUX Temp:    +34.5°C  (high = +127.0°C, hyst =  +0.0°C)  sensor = thermistor


Sensors is not reading a critical fan speed--nForce northbridge.
Sensors-detect requested that both the lm78 & w83627ehf get
loaded..running the latest Ubuntu kernel 2.6.27-2-generic

Thanks!!
