When I try to do something computationally intensive (such as lame

is producing high readings. Even when the system is 100% idle, the CPU
temperature is 61°C according to lm_sensors. The "high" value is 80°C,
and I believe the system shuts down if the CPU utilization goes too
high, even if the real temperature is much lower.
Can this be fixed by editing a configuration file or turning off the
broken thermistor?

You might be able to disable shutdown in the BIOS but I wouldn't do that
if I were you. It's entirely possible that the temps are real.
The first think you should do is see if your heatsink is covered with
dust, if it is you should clean it off. The second thing you should try
is to replace the thermal compound with something like Artic Silver or
Zalman. Remove the heatsink, clean off the bottom of the heat sink and
the top of the chip with a solvent (alcohol works fine for this) and then
put on a small amount of a good thermal paste on the CPU and replace the
heatsink. Chances are you will see a 5-10 degree drop in temperatures
which might be enough to fix your problem. If that doesn't do it then you
might want to invest in a better cooler.
