2. Set Fan Profile
Option Values: Performance
Acoustic
Help Text:
[Performance] - Fan control provides primary system cooling before attempting to throttle
memory.
[Acoustic] - The system will favor using throttling of memory over boosting fans to cool the
system if thermal thresholds are met.
Comments: This option allows the user to choose a Fan Profile that is optimized for
maximizing performance or for minimizing acoustic noise.
When Performance is selected, the thermal conditions in the system are controlled by raising fan speed
when necessary to raise cooling performance. This provides cooling without impacting system
performance, but may impact system acoustic performance fans running faster are typically louder.
The Performance mode is designed to provide sufficient cooling capability covering all kinds of add-in
cards on the market.
When Acoustic is selected, then rather than increasing fan speed for additional cooling, the system will
attempt first to control thermal conditions by throttling memory to reduce heat production. This regulates
the system’s thermal condition without changing the acoustic performance, but throttling memory may
impact system performance. The Acoustic mode offers best acoustic experience and appropriate
cooling capability covering mainstream and majority of the add-in cards.
The BMC only supports enabling a fan profile through the command if that profile is supported on all fan
domains defined for the given system. It is important to configure platform Sensor Data Records
(SDRs) so that all desired fan profiles are supported on each fan domain. If no single profile is
supported across all domains, the BMC, by default, uses profile 0 and does not allow it to be changed.

3. Fan PWM Offset
Option Values: [Entry Field 0 100, 0 is default]
Help Text:
Valid Offset 0 - 100. This number is added to the calculated PWM value to increase Fan Speed.
Comments: This is a percentage by which the calculated fan speed will be increased. The
user can apply positive offsets that result in increasing the minimum fan speeds. This feature is valid
when Quiet Fan Idle Mode is at Enabled state.

4. Quiet Fan Idle Mode
Option Values: Enabled
Disabled
Help Text:
Enabling this option allows the system fans to operate in Quiet ‘Fan off’ mode while still
maintaining sufficient system cooling. In this mode, fan sensors become unavailable and cannot
be monitored. There will be limited fan related event generation.
Comments: When enabled, this option allows fans to idle or turn off when sufficient thermal
margin is available, decreasing the acoustic noise produced by the system and decreasing system
power consumption. Fans will run as needed to maintain thermal control. The actual decrease in fan
speed depends on the system thermal loading, which in turn depends on system configuration and
workload.
