ASUS SmartDoctor2 is designed to satisfy two major goals. One is to monitor graphic chip Status, altering users about abnormal events, such as fan malfunction or chip overheat. The other, as the name SmartDoctor implies, is to cool down the graphic chip smartly when it is not necessary for it to be kept running at full speed. SmartDoctor2 includes AGP Power Level Monitoring, Fan RPM Monitoring, Overheated protection, Smartcooling technology, and Manual Overclocking.
