Platform Management Functional Overview Intel® Server Board S1200V3RP 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 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® Server System R1000RP product family Technical Product Specification and Intel® Server System P4000RP product family Technical Product Specification for system thermal and acoustic management. 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 Sensor1 Baseboard Temperature Sensor2 CPU Margin Sensors3, 5, 6 DIMM Thermal Margin Sensors3, 5 Exit Air Temperature Sensor1, 4, 8 PCH Temperature Sensor4, 6 On-board Ethernet Controller Temperature Sensors4, 6 Add-In Intel® SAS/IO Module Temperature Sensors4, 6 PSU Thermal Sensor4, 9 CPU VR Temperature Sensors4, 7 DIMM VR Temperature Sensors4, 7 Integrated BMC Temperature Sensor4, 7 Global Aggregate Thermal Margin Sensors8 Notes: 1.
