Interesting. I exited my X and back to bash/console, and GeForce 8800
GT's sensors results are different now.

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +21.8°C  (crit = +96.8°C)

k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:  +34.0°C
Core1 Temp:  +21.0°C

adt7473-i2c-4-2e
Adapter: NVIDIA i2c adapter
in1:         +2.94 V  (min =  +2.94 V, max =  +2.94 V)   ALARM
+3.3V:       +4.31 V  (min =  +4.31 V, max =  +4.31 V)
fan1:         82 RPM  (min =   82 RPM)  ALARM
fan2:         82 RPM  (min =   82 RPM)  ALARM
fan3:         82 RPM  (min =   82 RPM)  ALARM
fan4:         82 RPM  (min =   82 RPM)  ALARM
temp1:        -5.0°C  (low  =  -5.0°C, high =  -5.0°C)  ALARM
Board Temp:   -5.0°C  (low  =  -5.0°C, high =  -5.0°C)  ALARM
temp3:        -5.0°C  (low  =  -5.0°C, high =  -5.0°C)  ALARM

Is that normal especially for the temperature readings?
