Six VID Inputs (VID0 to VID5) for VRM10 Support.
Three PWM Outputs for Fan Control of up to Three
Fans. (All three fans can be individually controlled.)
Three TACH Fan Speed Measurement Inputs.
V
CPU Core Voltage Measurement (V
2.5 V Measurement Input Used to Monitor CPU Cur-
rent (connected to V
Controller). This is used to determine CPU power
consumption.
