How to enable AMD Cool ‘n’ Quiet in Windows 7
In Windows XP there’s a driver and utility (on the ASUS Support site) for the Cool ‘n’ Quiet functionality. (It throttles CPU speed when not needed to reduce heat and power consumption). But in newer versions of Windows, there’s no driver available because it’s not needed; Windows supports it natively. First, make sure it is enabled in the BIOS. Then, open Power Options from the Control Panel and set it to Balanced or Power Saver mode. Either of these will activate the Cool ‘n’ Quiet functionality.
I verified this in Windows 7 (64-bit) using CPU-Z. When it’s working, the Core Speed and Multiplier will change according to the processing load.
