Thermal paste can get hard and stop conducting heat. Also, the heatpipes 
can fail and quit moving the heat from the processor or GPU over to the 
heat exchanger (the little radiator and fan.) Both will cause CPU to 
throttle way down.

See if it's an issue, if so may need to remove the heatpipe setup or 
heatsink and respooge it.
