CPU1 Temperature: This item displays CPU1 Temperature.

CPU2 Temperature: This item displays CPU2 Temperature.

System Temperature: This item displays the System Temperature.

Fan Speed Control Modes

This feature allows the user to decide how the system controls the speeds

of the onboard fans. If the option is set to "3-pin fan", the fan speed is

controlled based upon the CPU die temperature. When the CPU die tempera-

ture is higher, the fan speed will be higher as well. If the option is set to "4-

pin", the fan speed will be controlled by the Thermal Management Settings

pre-configured by the user at this feature. 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 the fan speed control function to allow the onboard fans to run at

the full speed (12V) at all time. The Options are: 1. Disable, 2. 3-pin

(Server), 3. 3-pin (Workstation), 4. 4-pin (Server), 5. 4-pin (Workstation).
