Intel order number G42278-004
[SCLTT] – Static Close Loop Thermal Throttling: for the SOD DIMM without system airflow
input
[SOLTT] – Static Open Loop Thermal Throttling: for the DIMMs without sensor on DIMM
(SOD)
The default setting is [Auto].
6.9.1.2
Altitude
Select the proper altitude that the system is distributed from [300m or less], [301m-900m],
[901m-1500m], [Above 1500m] options. Lower altitude selection can lead to potential thermal
risk. And higher altitude selection provides better cooling but with undesired acoustic and fan
power consumption. If the altitude is known, higher altitude is recommended in order to provide
sufficient cooling. The default setting is [301m – 900m].
6.9.1.3
Set Fan Profile
[Performance] and [Acoustic] fan profiles are available to select. The Acoustic mode offers best
acoustic experience and appropriate cooling capability covering mainstream and majority of the
add-in cards. Performance mode is designed to provide sufficient cooling capability covering all
kinds of add-in cards on the market. The default setting is [Performance].
6.9.1.4
Fan PWM Offset
This feature 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].
6.9.1.5
Quiet Fan Idle Mode
This feature can be [Enabled] or [Disabled]. If enabled, the fan will either stopped or shift to a
lower speed when the aggregate sensor temperatures are satisfied indicating the system is at
ideal thermal/light loading conditions. When the aggregate sensor temperatures not satisfied,
the fan will shift back to normal control curves. If disabled, the fan will never stopped or shift into
lower fan speed whatever the aggregate sensor temperatures are satisfied or not. The default
setting is [Disabled].
Note
:
1. The above features may or may not be in effective depends on the actual thermal
characters of a specific system.

6.9.1.6
Thermal Sensor Input for Fan Speed Control
The BMC uses various IPMI sensors as inputs to FSC. Some of the sensors are actual
physical sensor and some are “virtual” sensors derived from calculation.
The following IPMI thermal sensors are used as input to the fan speed control:
Front Panel Temperature Sensor

Baseboard Temperature Sensor
