4.2 Thermal Management Overview
In order to maintain the necessary airflow within the system, all of the previously listed
components and top cover need to be properly installed. For best system performance, the
external ambient temperature should remain below 35ºC and all system fans should be
operational.
Note: All system fans are controlled independent of each other. The fan control system may
adjust fan speeds for different fans based on increasing/decreasing temperatures in different
thermal zones within the chassis.
In the event that system thermals should continue to increase with the system fans operating at
their maximum speed, platform management may begin to throttle bandwidth of either the
memory subsystem or the processors or both, in order to keep components from overheating
and keep the system operational. Throttling of these sub-systems will continue until system
thermals are reduced below preprogrammed limits.
Should system temperatures increase to a point beyond the maximum thermal limits, the
system will shut down, the System Status LED will change to a solid Amber state, and the event
will be logged to the system event log.
Note: Sensor data records (SDRs) for any given system configuration must be loaded by the
system integrator for proper thermal management of the system. SDRs are loaded using the
FRUSDR utility.
An intelligent Fan Speed Control (FSC) and thermal management technology (mechanism) is
used to maintain comprehensive thermal protection, deliver the best system acoustics, and fan
power efficiency. Options in <F2> BIOS Setup (BIOS > Advanced > System Acoustic and
Performance Configuration) allow for parameter adjustments based on the actual system
configuration and usage. Refer to the following sections for a description of each setting.
4.2.1 Set Throttling Mode
This option is used to select the desired memory thermal throttling mechanism. Available
settings include:
[Auto], [DCLTT], [SCLTT] and [SOLTT].
[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)
4.2.2 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].
