One major cause of excessive heat is excessive dust on the heat sink, cpu fan and power supply.<br>Is the heat sink making proper contact with cpu? Try applying some thermal grease. Also,you may install a case fan.<br><br>

</div>Thanks. The machine has shown mild signs of flakiness in the past when called<br>
upon for CPU-intensive tasks (say compiling gcc) -- random segfaults that would<br>
go away if I let it cool down a bit. Now it glitches on compiling gimp or some<br>
qt libraries. Mind you, it has been a hot summer, and the ambient temperature<br>
in the room in which it is located is about 26C. But lm-sensors doesn't show<br>
an abnormally high core temperature.<br>
<br>
I'll try to cool it down to see whether that matters, but it sounds like it's<br>
time to think about getting a more reliable (and well-cooled) computer. Time<br>
to post a general query.<br>
<br>
Thanks for the help!<br>
