9.1.1
Set Throttling Mode
This option is used to select the desired memory thermal throttling mechanism. Available
settings include:
 [Auto] – Factory Default Setting - BIOS automatically detects and identifies the
appropriate thermal throttling mechanism based on DIMM type, airflow input, and 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)
9.1.2
Altitude
This option is used to select the proper altitude that the system will be used in. Available
settings include: [300m or less], [301m-900m], [901m-1500m], [Above 1500m].
Selecting an altitude range that is lower than the actual altitude the system will be operating at,
can cause the fan control system to operate less efficiently, leading to higher system thermals
and lower system performance. If the altitude range selected is higher than the actual altitude
the system will be operating at, the fan control system may provide better cooling but with
higher acoustics and higher fan power consumption. If the altitude is not known, selecting a
higher altitude is recommended in order to provide sufficient cooling.
9.1.3
Set Fan Profile
This option is used to set the desired Fan Profile. Available settings include:
[Performance] and [Acoustic].
The Acoustic mode offers the best acoustic experience and appropriate cooling capability
covering the mainstream and the majority of the add-in cards used. Performance mode is
designed to provide sufficient cooling capability covering all kinds of add-in cards on the market.
9.1.4
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].
9.1.5
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.
