Throttling Mode
Open Loop
Closed Loop
Open Loop does not rely on a thermal
sensor on the board and sets up a static
level which equates to a fixed bandwidth.
Closed Loop will allow the system to
achieve higher performance by monitoring
system temps and adjusting bandwidth.
Set Fan Profile
Performance
Acoustic
Select the fan control profile that will be
used to cool the system.
Performance mode favors
using fans over throttling
memory bandwidth to cool
the system.
Note: This option is only
available when Open Loop
Throttling Mode is selected.
Altitude 300 M or less
301 M - 900 M
Higher than 900 M
300 M or less (<= 980ft): Provides the best
performance option for servers operating
at or near sea level.
301 M – 900 M (980ft - 2950ft): Provides
the best performance option for servers
operating at moderate altitudes above sea
level.
Higher than 900 M (>2950ft): Provides the
best performance option for servers
operating at high elevations above sea
level.
Note: This option is
unavailable when the BIOS
supports Closed Loop
Throttling Mode.
Note: Fan speed control for non-Intel chassis, as configured after running the FRUSDR utility
and selecting the Non-Intel Chassis option, is limited to only the CPU fans. The BMC only
requires the processor thermal sensor data to determine how fast to operate these fans. The
remaining system fans will operate at 100% operating limits due to unknown variables
associated with the given chassis and its fans. Therefore, regardless of whether the system is
configured for Performance Mode or Acoustics Mode, the System fans will always run at 100%
operating levels providing for maximum airflow. In this scenario the Performance and Acoustic
mode settings only affects the allowable performance of the memory (higher BW for the
Performance mode).
3.4.2.4 Performance Mode (Default)
With the platform running in Performance mode (Default), several platform control algorithm
variables are set to enhance the platform’s capability of operating at maximum performance
targets for the given system. In doing so, the platform is programmed with higher fan speeds at
lower external temperatures. This will result in a louder acoustic level than is targeted for the
given platform, but the increased airflow of this operating mode will greatly reduce possible
memory throttling from occurring and will reduce dynamic fan speed changes based on
processor utilization.
3.4.2.5 Acoustics Mode
With the platform running in Acoustics mode, several platform control algorithm variables are set
to ensure acoustic targets are not exceeded for specified Intel platforms. In this mode, the
platform is programmed to set the fans at lower speeds when the processor does not require
