Technical Product Specification

Thermal Management Intel® Server System P4000IP and Intel® Workstation System P4000CR Family TPS

Revision 1.2 Intel order number G38159-002

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.

3.2.1 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, 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].

3.2.2 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].

3.2.3 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].

3.2.4 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].

3.2.5 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]
