Thanks for your reply Matt. I ran sensors and it reported the following:

smsc47m192-i2c-0-2d
Adapter: SMBus I801 adapter at 2000
+2.5V:       +2.55 V  (min =  +0.00 V, max =  +3.32 V)   
VCore:       +1.20 V  (min =  +0.00 V, max =  +2.99 V)   
+3.3V:       +3.28 V  (min =  +0.00 V, max =  +4.38 V)   
+5V:         +4.97 V  (min =  +0.00 V, max =  +6.64 V)   
+12V:       +12.25 V  (min =  +0.00 V, max = +15.94 V)   
VCC:         +3.32 V  (min =  +0.00 V, max =  +4.38 V)   
+1.5V:       +1.58 V  (min =  +0.00 V, max =  +1.99 V)   
+1.8V:       +1.78 V  (min =  +0.00 V, max =  +2.39 V)   
Chip Temp:   +31.0°C  (low  = -127.0°C, high = +127.0°C)  
CPU Temp:    +50.0°C  (low  = +40.0°C, high = +70.0°C)  
Sys Temp:    +40.0°C  (low  = -127.0°C, high = +127.0°C)  
cpu0_vid:   +2.050 V

smsc47m1-isa-0680
Adapter: ISA adapter
fan1:       4818 RPM  (min = 1280 RPM, div = 4)
fan2:       7021 RPM  (min = 1280 RPM, div = 4)

And then checked the version:

sensors version 3.0.2 with libsensors version 3.0.2

You do know your stuff! Thank you much. Any ideas as to the code in the snippet
in the other message? I'm running LCD4Linux to access the LCD.
