Kubuntu causing computer to overheat. (I think)

OK, so if lm-sensors is installed that explains where you're getting 
temperature readings, but it doesn't explain why you're getting outer space 
readings for your temperatures.  Have you checked /etc/sensors.conf for your 
sensors and motherboard?  It already has many of the known troublesome boards 
and chips documented, along with the correct lines to make them function.  
The full documentation and forums are at http://lm-sensors.org/ and could be 
of help.

Also, are there really current motherboards out there that don't have at least 
rudimentary temperature reporting in the BIOS?  I know that it's been common 
on even cheap boards since around 2000/2001, so I would be surprised if your 
board doesn't have it.  If you have sensors to dectect at all, then it would 
be surprising if you don't have a report in the BIOS configuration somewhere, 
otherwise there would be no purpose in having the sensors.
