It works by reducing the processor’s clock rate and voltage when the processor is idle. The original Phenom only had two p-states: Should I turn this on or off? In addition to the CPU drivers offered by AMD, several motherboard manufacturers have released software to give the end user more control over the Cool ‘n’ Quiet feature, as well as the other new features of AMD processors and chipsets.

If you were running a single threaded application, the core that your thread was active on would run at full speed, while the remaining three cores would run at a much lower speed. The feature is not a Windows component and is not packaged with the operating system.

The aim of this technology is to reduce overall power consumption and lower heat generation, allowing for slower thus quieter cooling fan operation.

I expect that CnC per-core caused no problems under linux for example In order to be able to post messages on the Overclock.

Originally Quket by Adamantus. Due to their different usage, Cool’n’Quiet refers to desktop and server chips, while PowerNow! Well it basicly lowers the clock speeds on ur cpu when not needed.

Honestly, AMD’s initial Phenom approach is more elegant, but unfortunately the current task scheduling mechanism causes problems. Wow, I just found the solution here: Retrieved cool n quiet ” https: By echy Started 45 minutes ago Posted in Storage Devices.

And quet output for cpufreq-info is: Anyway, thanks to everyone.

If the temperature within the CPU decreases, the fan’s speed decreases and the fan could possibly shut off if the Cool ‘n’ Quiet feature determines that the fan doesn’t need to run.

December 24th, Cool n quiet was wondering if a anyone else had encountered this, b anyone fool offer an explanation, c there are any negatives I need to be aware of if I keep AMD Cool n quiet disabled.

It just not worth, lets say, surfing the internet at 4. You can easily verify this on Linux by installing indicator-cpufreq. The original Phenom was the first quad-core x86 CPU to allow cool n quiet core to operate at an independent p-state.

If you were running a single threaded cool n quiet, the core that your thread was active on would run at full speed, while the remaining three cool n quiet would run at a much quist speed. I was able to prove it was CnQ from both dump evidence consistently implicating the CPU driver and anecdotally from multiple tests enabling and disabling it, with repeatable behavior in each case.

After some fairly extensive testing I have concluded that CnQ definitely does significantly negatively impact the performance of my system.
