CIM_LogicalElement 45
CIM_Fan
The CIM_Fan class explained in Table 3-19 contains a set of devices that work to keep the ambient
internal temperature of the system at a safe value by circulating air.
CIM_UserDevice
The CIM_UserDevice class shown in Table 3-20 contains logical devices that allow a computer system’s
users to input, view, or hear data. Classes derived from CIM_UserDevice include CIM_Keyboard and
CIM_PointingDevice.
Table 3-19. CIM_Fan Properties
Class Name: CIM_Fan
Parent Class: CIM_CoolingDevice
Property Description Data Type
VariableSpeed Specifies whether the fan supports variable speeds. Boolean
DesiredSpeed Indicates the currently requested fan speed, defined in RPM. When the value
= TRUE, the fan supports variable speeds. When a variable speed fan is
supported (VariableSpeed Boolean = TRUE), the actual speed is determined
using a sensor (CIM_Tachometer) that is associated with the fan.
