This is for those of you who are not aware of what the main function of the DD5 is. DD5 is a device which basically monitors the temperature of various components in your case, and at the same time powers up to 8 cooling fans in your system. The really great thing about this device is that it will also warn you about any abnormalities that can happen to your PC while you are overclocking. Basically in my books a definite must have hardware in my PC.
