True, I've considered it, I'll replace the CPU fan.

No, much older than that:

Well, I have had a thought. I recently upgraded the toolchain on the machine 
from binutils 2.16.x and GCC 3.4.3 (2.6.19 was built with this) to binutils 
2.17 and GCC 4.1.1. It's conceivable that this is some sort of compiler bug.
