Hardware Health Configuration

CPU Overheat Alarm

This setting allows you to specify the type of alarm for CPU overheating. Options include The Early Alarm and The Default Alarm.

Fan Speed Control Modes

This feature allows the user to determine how the system will control the speed of the onboard fans. The options are Full Speed/FS (Max Cooling), Performance/ PF (Better Cooling), Balanced/BL (Balance between performance and energy saving), Energy Saving/ES (Lower Power and Noise).

Other items in the submenu are systems monitor displays for the following information:

CPU 1 Temperature, CPU 2 Temperature, System Temperature, Fan 1-2 Reading, CPU 1 VCore, CPU 2 VCore, CPU 1 Mem VTT, CPU 2 Mem VTT, CPU 1 Mem, CPU 2 Mem, 1.1V, 1.8V, 5V, +12V, 3.3 Vcc, 3.3 VSB, VBAT and HT Voltage.

CPU Temperature Display (CTD)

CPU Temperature descriptions are defined as:

Low [Tctl Value = Lowest Value, Tctl Value = -45]

Medium [Tctl Value = -46, Tctl Value = 60]

High [Tctl Value = -61 and Above]

Note: Only CPU temperature (Low, Medium, High) and system temperature (RT1) are required to be displayed in BIOS and in-system monitoring software. Other Serverboard components such as memory, chipset, SAS and 10Gb controllers, and others are not requried to display temperatures. For debugging and testing purposes, BIOS and system monitoring software can show motherboard components’ temperatures (such as memory, chipset, SAS and 10Gb controllers). However for SMCI standard release version BIOS and system monitoring software, motherboard components’ temperatures are NOT required to be displayed.

CPU Overheating Alarm (COA)

CPU Overheating Alarm (COA) has “Early Alarm” and “Default Alarm” (default) options in the BIOS, and is required to be implemented in all fan speed control modes.

The Early Alarm is enabled when the Tctl value = 65, and is disabled when the Tctl value drops from 65 to 62.
