A fan domain is an area where fan panels are installed. Each fan domain contains a list of fan panels. Each fan panel contains a list of fans and temperature sensors. To control the fan speed, call SetFanDomainModeAsync and pass the expected mode from FanDomainMode as an input parameter to change the fan speed.

  • FanDomainMode.High: the fan speed is set to FanDomainMaxRpm for the fans in the fan panels of the target fan domain.
  • FanDomainMode.Manual: the fan speed is set to the user-defined fan RPM. To set a user-defined fan speed, call SetFanDomainUserDefinedRpmAsync.
    Note If the fan domain mode is set to FanDomainMode.Manual when a user-defined RPM is not set, the fan RPM will be set to FanDomainMinRpm. The user-defined RPM cannot be set higher than FanDomainMaxRpm or lower than FanDomainMinRpm.
    Note When the RCU is in standby mode, querying the fan RPM using ReadRpmAsync may return an incorrect value of 4294967295. This value is generated by the default hardware behavior and can be disregarded.
