I fully understand that RivaTuner can control the speed of both fans in a SLI setup. But when SLI is not enabled, Scheduler and Launcher can only activate custom fan profiles associated with the currently selected target adapter. Does anyone know of a workaround for this behavior? I would like to be able to control the fans on both cards when SLI is not enabled also. Thanks.
There is no workaround, with fully independent display adapters you can only apply independent fan settings to each display device at windows startup. Launcher and scheduler apply only to currently selected display device by design, you won't be able to use these features to control multiple display devices simultaneously.
