contribute to the cooling requirements, primarily memory bandwidth. The BIOS, BMC, and
SDRs work together to provide control over how this trade-off is determined.
SDRs work together to provide control over how this trade-off is determined.
This capability requires the BMC to access temperature sensors on the individual memory
DIMMs. Additionally, closed-loop thermal throttling is only supported with buffered DIMMs.

6.11.2
Setting Throttling Mode
Select the most appropriate memory thermal throttling mechanism for memory sub-system from
[Auto], [DCLTT], [SCLTT] and [SOLTT].
[Auto], [DCLTT], [SCLTT] and [SOLTT].
[Auto] – BIOS automatically detect and identify the appropriate thermal throttling
mechanism based on DIMM type, airflow input, DIMM sensor availability.
[DCLTT] – Dynamic Closed Loop Thermal Throttling: for the SOD DIMM with system
airflow input
[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].
6.11.3
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].

6.11.4
Set Fan Profile
The [Performance] and [Acoustic] fan profiles in BIOS must be selected in [BIOS > Advanced >
System Acoustic and Performance Configuration > Set Fan Profile]. The Acoustic mode
offers best acoustic experience and appropriate cooling capability covering mainstream and
majority of the add-in cards with 100LFM thermal requirements. For any add-in card requiring
more than 100LFM, performance mode must be selected to provide sufficient cooling capability.

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].

This feature is valid when Quiet Fan Idle Mode is at Enabled state. The default setting is [0].
6.11.6
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].
