21 Custom Cooling Fan Options for Dell EMC PowerEdge Servers
FanSpeedHighOffsetVal
• Getting this variable
reads the fan speed
offset value in
%PWM for High Fan
Speed Offset
setting.
• This value is
platform-dependent.
• Use
FanSpeedOffset to
set this value using
index value 1.
Values
from 0-100
racadm get
system.thermalsettings
FanSpeedHighOffsetVal
This returns a value like “75” meaning that
when you use the command “racadm set
system.thermalsettings FanSpeedOffset
1”, it applies a fan speed offset of High
(75% PWM) over baseline fan speed.
FanSpeedLowOffsetVal
• Getting this variable
reads the fan speed
offset value in
%PWM for Low Fan
Speed Offset
setting.
• This value is
platform-dependent.
• Use
FanSpeedOffset to
set this value using
index value 0.
Values
from 0-100
racadm get
system.thermalsettings
FanSpeedLowOffsetVal
This returns a value like “25,” meaning that
when you use command“racadm set
system.thermalsettings FanSpeedOffset
0”, it applies a fan speed offset of Low
(25% PWM) over baseline fan speed.
FanSpeedMaxOffsetVal
• Getting this variable
reads the fan speed
offset value in
%PWM for Max Fan
Speed Offset
setting.
• This value is
platform-dependent.
• Use
FanSpeedOffset to
set this value using
index value 3.
Values
from 0-100
racadm get
system.thermalsettings
FanSpeedMaxOffsetVal
This returns a value like “100,” meaning
that when you use command“racadm set
system.thermalsettings FanSpeedOffset
3”, fan speed offset of Max (meaning full
speed, 100% PWM) is applied. Usually,
this offset results in fan speeds going to
full speed.
FanSpeedMediumOffset
Val
• Getting this variable
reads the fan speed
offset value in
%PWM for Medium
Fan Speed Offset
setting.
• This value is
platform-dependent.
• Use
FanSpeedOffset to
set this value using
index value 2.
Values
from 0-100
racadm get
system.thermalsettings
FanSpeedMediumOffsetVal
Returns a value (for example) “50,”
meaning that when you use
command“racadm set
system.thermalsettings FanSpeedOffset
2”, a fan speed offset of Medium (50%
PWM) over baseline fan speed is applied.
