Intel® Server Board S2600IP and Intel® Workstation Board W2600CR TPSPlatform Management Overview
Revision 1.1 61
Intel order number G34153-003
4.4.4 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].
4.4.5 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 :
1. The above features may or may not be in effective depends on the actual thermal
characters of a specific system.
2. Refer to System TPS for the board in Intel chassis thermal and acoustic management
3. Refer to Fan Control Whitepaper for the board in third party chassis fan speed control
customization.
4.4.6 Thermal Sensor Input for Fan Speed Control
The BMC uses various IPMI sensors as inputs to FSC. Some of the sensors are actual
physical sensor and some are
“virtual” sensors derived from calculation.
The following IPMI thermal sensors are used as input to the fan speed control:

Front Panel Temperature Sensor
1

Baseboard Temperature Sensor
2

CPU Margin Sensors
3,5,6

DIMM Thermal Margin Sensors
3,5

Exit Air Temperature Sensor
