Intel® Server Board S1200V3RP TPS Platform Management Functional Overview
Revision 1.2
might require a trade-off between fan speed and system performance parameters that
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.
This capability requires the BMC to access temperature sensors on the individual memory
DIMMs.
In order to maintain comprehensive thermal protection, deliver the best system acoustics, and
improve fan power efficiency, an intelligent Fan Speed Control (FSC) and thermal management
technology (mechanism) is used. Options in <F2> BIOS Setup (BIOS > Advanced > System
Acoustic and Performance Configuration) allow for parameter adjustments based on the
actual system configuration and usage:
Set Throttling Mode
Altitude
Set Fan Profile
Fan PWM Offset
Quiet Fan Idle Mode
Note: The above features may or may not be in effective depends on the actual thermal
characters of a specific system. Refer to Intel

6.10.2 Thermal Sensor Input to Fan Speed Control
The BMC uses various IPMI sensors as input to the fan speed control. Some of the sensors are
IPMI models of actual physical sensors whereas some are virtual sensors whose values are
derived from physical sensors using calculations and/or tabular information.
The following IPMI thermal sensors are used as input to the fan speed control:
Front Panel Temperature Sensor

CPU Margin Sensors
3, 5, 6
DIMM Thermal Margin Sensors
