ASUS has a unique software called EPU-6 Engine that monitors your energy consumption and CO2 emissions of your system. I have utilized this software and have found it to be dependable and beneficial. It allows the system to exhibit minimal cooling to maximum cooling, either auto or manual settings. Completely configurable through the GUI, this software is a must for the gaming machine that has many cooling fans.
System Level Energy Saving
The new ASUS EPU – the world’s first power saving engine, has been upgraded to a new 6 engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. With auto phase switching for components (which includes the CPU, VGA card, memory, chipset, hard drives and CPU cooler/system fans), the EPU automatically provides the most appropriate power usage via intelligent acceleration and overclocking – helping save power and money.

If you choose to use this energy saver, you will find that it will significantly lower the sound output of the cooling fans within your case. After you calibrate it to your system, you will want to use the AUTO mode to allow the system to monitor the cooling and to adjust accordingly. It can be manually adjusted as well with the click of your mouse. Since I am running an ASUS board it works fine for me.
