cpu overheat during compiles

[Cecil H. Whitley]

I noticed this previously, got a can of air and blew the dust out of the cpu 
fan.  That resolved it for me.  Unfortunately, I have to repeat the process 
about every 2 or 3 months.  Most newer cpu's run hot and need good air 
circulation.  I've actually got 4 case fans, but if I don't keep the cpu fan 
clean it still runs hot.  I've considered getting a larger heat sink/fan for 
the cpu, but the system needs a good dusting anyway.
