So in doing some more research I finally got together the nerve to disassemble 
my laptop.  After cleaning a massive amount of thermal paste off the cpu and 
heatsink it's operating around 60C after multiple make -j4 buildworlds, where 
it used to shut down due to going over 100C.

It seems I'm not the first person to discover this was the root cause of their 
heat and noise problems with their Lenovo T60/61 laptop.

I've also been able to turn over control of the fan back to the BIOS as 
opposed to running it full out all the time.
