Technical Product Specification

Thermal and Acoustic Management Intel® Server System R2000IP Product Family TPS
36 Revision 1.1
management technology (mechanism) is developed. Options reserved for end users to adjust
parameter settings based on the actual system configuration and usage in BIOS interface with
path: BIOS > Advanced > System Acoustic and Performance Configuration. Refer to below
to setup the system thermally right.
4.2.1 Set Throttling Mode
Select the most appropriate memory thermal throttling mechanism for memory sub-system from
[Auto], [DCLTT], [SCLTT] and [SOLTT].
 [Auto] – BIOS automatically detect and identify 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)
The default setting is [Auto].
4.2.2 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].
4.2.3 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]
4.2.4 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].
4.2.5 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: The above features may or may not be in effective depends on the actual thermal
characters of a specific system. Refer to specific system for additional information.
