Amd Cool N Quiet Driver _best_ -

With less heat to dissipate, the system’s cooling fans can spin slower, leading to a "quiet" computing experience.

AMD Cool 'n' Quiet (CnQ) is a dynamic frequency scaling technology that reduces a processor's clock rate and voltage when it is idle. With less heat to dissipate, the system’s cooling

(tested on Phenom II X6 1100T):

In the early 2000s, the race for processor speed created a heat problem. As CPU clock rates climbed, so did power consumption and fan noise. AMD’s answer to this was (CnQ), a technology introduced initially for their Athlon 64 processors. It was one of the first widespread implementations of dynamic voltage and frequency scaling for consumer desktop CPUs. As CPU clock rates climbed, so did power
