2.  Altitude 
Option Values:    300m or less 
 301m-900m
 
   901m-1500m 
   Higher than 1500m 
Help Text: 
[300m or less] (980ft or less) 
Optimal performance setting near sea level. 
[301m - 900m] (980ft - 2950ft) 
Optimal performance setting at moderate elevation. 
[901m - 1500m] (2950ft - 4920ft) 
Optimal performance setting at high elevation. 
[Higher than 1500m] (4920ft or greater) 
Optimal performance setting at the highest elevations. 
Comments:    This option sets an altitude value in order to choose a Fan Profile that is 
optimized for the air density at the current altitude at which the system is installed.

3.  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 sets an altitude value in order to choose a Fan Profile that is 
optimized for the air density at the current altitude at which the system is installed.

4.  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.
