different system functions in a user-friendly interface, which includes 
Hardware Monitor, Fan Control, Overclocking, OC DNA and IES. In Hard-
ware Monitor, it shows the major readings of your system. In Fan Control, 
it shows the fan speed and temperature for you to adjust. In Overclock-
ing, you are allowed to overclock CPU frequency for optimal system per-
formance. In OC DNA, you can save your OC settings as a profile and 
share  it  with  your  friends. Your  friends  then  can  load  the  OC  profile  to 
their own system to get the same OC settings. In IES (Intelligent Energy 
Saver), the voltage regulator can reduce the number of output phases to 
improve efficiency when the CPU cores are idle without sacrificing com-
puting performance. Please visit our website for the operation procedures
