Fun with undervolting - 5 to 10 degree C drop in heat under heavy load

I may have a special CPU in my Thinkpad. It operates just fine at the 12x multiplier with a voltage of 1.0750V. The default for this Core Duo core is 1.2625V. I can go lower, in fact, very close to 1.0V, but at that point, one of the two cores fail.

Why bother with this? Less fan noise, less power consumption, and lower temperatures. I have a bad habit of really giving my workstations and laptops a real workout when I have a lot of things going on. I have in the past triggered thermal events which caused the system to shutdown.

I can now run as many VMs, Dreamscenes, and applications I want and not worry about the temperature going over 80C.
