On an ASUS mobo u have some unique ASUS features like EPU engine and Q-fan. EPU helps to save some energy wile u don,t need much power,is very easy to use. Q-fan is like a rheobus, but is a software that help to regulate the fan speed on a system, based on temperatures. If u don't have these installed yet go to the ASUS web site support, specially for Win 7 support . U may use also the AMD Cool&Quiet feature to get the same results. U will find these on "utilities" section. I think u can access the Q-fan utility from the BIOS, or using PC ProbeII as a program in Windows.
