Krusty, 'normal' cpu's haven't been running at 100% for the past 5 years if you enabled the power and heat saving functions. Why should your CPU run at full burn when it's not at use?
Amd has 'Cool&Quiet' which also helps lowering cooling fan speeds and Intel has speedstep and other methods for doing the same. They give no performance hit.
Agreed... not sure of the time limit, but all the MB makers have gone green so to speak, all processors are throttled down unless you disable it in the bios. An easy way to see this is using CPU-Z, it will show the processor throttling down (E8400) from 3.0 to 2.4GHz, each board manufacture has their own idea of throttle down. ASUS, EVGA, Gigabyte all have the options easily accessible in the BIOS
