I don’t know about your setup but for most people it’s impossible to replicate the cooling effects provided by riding outdoors. Even with fans and a cold room I’m much hotter indoors than outdoors. Increased core temperature makes riding indoors feel harder once your power is above 250W or so. At lower power levels it probably doesn’t matter.
