Chapter 7: BIOS
Hardware Monitor Logic
Note: The Phoenix BIOS will automatically detect the type of CPU(s) and hardware monitoring chip used on the motherboard and will display the Hardware Monitoring screen accordingly.
CPU Temperature Threshold
This option allows the user to set a CPU temperature threshold that will activate the alarm system when the CPU temperature reaches this pre-set temperature threshold. The options are 75oC, 80oC, 85oC and 90oC. Highlight this and hit <Enter> to see monitor data for the following items:
CPU Temperature/CPU Second Core Temperature
System Temperature
Fan1-Fan6 Speeds: If Auto Fan Control is enabled, the BIOS will automatically display the status of the fans indicated in this item.
Fan Speed Control Modes
This feature allows the user to decide how the system controls the speeds of the onboard fans. The CPU temperature and the fan speed are correlative. When the CPU on-die temperature increases, the fan speed will also increase, and vice versa. When this option is to 3-pin fan, the fan speed will be controlled by voltage. Select “Disable” to disable the fan speed control function and allow the onboard fans to constantly run at full speed (12V). If the option is set to 4-pin, the fan speed will be controlled by Pulse Width Modulation (PWM). Select 3-pin if your chassis came with 3-pin fan headers. Select 4-pin if your chassis came with 4-pin fan headers. Select Workstation if your system is used as a Workstation. Select Server if your system is used as a Server. Select Disable to disable fan speed control and al- low the onboard fans to constantly run at full speed (12V). The Options are: 1. Disable, 2. 3-pin (Server), 3. 3-pin (Workstation), 4. 4-pin (Server) and 5. 4-pin (Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
Vcore, Vcc 1.5V, -12, Vcc 1.8V, +3.3V, +12V, 5Vsb, 5VDD, Vfsb, Vbat
