5.2.3
Set Fan Profile
This option is used to set the desired Fan Profile. Available settings include:
[Performance] and [Acoustic].
Performance mode is designed to provide sufficient cooling capability covering all kinds of add-
in cards on the market. The Acoustic mode offers the best acoustic experience and appropriate
cooling capability supporting the majority of the add-in cards used.
5.2.4
Fan PWM Offset
This option is reserved for manual adjustment to the minimum fan speed curves. The valid
range is from [0 to 100] which stands for 0% to 100% PWM adding to the minimum fan speed.
This feature is valid when Quiet Fan Idle Mode is at Enabled state. The default setting is [0].
5.2.5
Quiet Fan Idle Mode
This feature can be [Enabled] or [Disabled]. If enabled, the fans will either shift to a lower
speed or stop when the aggregate sensor temperatures are satisfied, indicating the system is at
ideal thermal/light loading conditions. When the aggregate sensor temperatures are not
satisfied, the fans will shift back to normal control curves. If disabled, the fans will never shift
into lower fan speeds or stop, regardless of whether the aggregate sensor temperatures are
satisfied or not. The default setting is [Disabled].
Note: The above feature may or may not be in effect and depends on the actual thermal
characteristics of the specified system.
5.2.6
Thermal Sensor Input for Fan Speed Control
The BMC uses various IPMI sensors as inputs to fan speed control. Some of the sensors are
actual physical sensors and some are “virtual” sensors derived from calculations.
The following IPMI thermal sensors are used as input to fan speed control:
 Front Panel Temperature Sensor
1
 Baseboard Temperature Sensor
2
 CPU Margin Sensors
3, 5, 6
 DIMM Thermal Margin Sensors
3, 5
 Exit Air Temperature Sensor
4, 8
 PCH Temperature Sensor
4,6
 On-board Ethernet Controller Temperature Sensors
4, 6
 Add-In Intel
