Chapter 1: Introduction CPU Overheat LED and Control This feature is available when the user enables the CPU overheat warning func- tion in the BIOS. This allows the user to defi ne an overheat temperature. When the CPU temperature passes this threshold, both the overheat fan and the warning LED are triggered.
It is even more important for processors that have high CPU clock rates. The X7DWE can accommodate 24-pin ATX power supplies. Although most power supplies generally meet the specifi cations required by the CPU, some are inad- equate. In addition, the 12V 8-pin power connections are also required to ensure adequate power supply to the system.
