Performance
Acoustics
[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.
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.
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.
Fan PWM
Offset
Entry Field 0 –
100, 0 is default
Valid Offset 0 - 100. This number is
added to the calculated PWM value
to increase Fan Speed.
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.
Quiet Fan Idle
Mode
Disabled
Enabled
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.
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.
While Quiet Fan Idle Mode is
engaged, fan sensors become
unavailable and are not monitored by
the BMC.
