I had a problem with a G4 Mac Mini that kept overheating.  This was 
under OS X.  The fan would be howling away at high speed the whole time 
but it would still overheat.  I disassembled it and found the heatsink 
was packed completely full of lint.  I suppose that's unlikely on a 
"fairly new"  machine, though; the one I was dealing with was about 
three years old.

It sounds like you're using Linux.  You might want to make sure ACPI is 
enabled in the kernel.  A lot of machines rely on it for fan speed 
control, these days.
