I could read many contradictory observations/informations about this fan function/noise problem. It seems that every player behave different from another in this (cooling) field. This is definitively an (design) issue, which Oppo may take a closer look on. One may know that the main processor run very hot anyway, the most of it heat is spreading out through the bad thermal conducting chassis, and the fan it self help very little to cool down that processor (which include the temp control circuit).
In my case I had a quite normal function of the fan inside my player. It just got started intermittent when the heat were to high inside. Only the noise of this working fan were very uncomfortable to me. So, I decided to fix this. I mounted an bigger heat sink on the main processor (the motherboard was specially designed for the use of an enough big heat sink on the processor, but in fact Oppo decided to use a very small metal plate and some special compound to cool down that chip).
After mounting a bigger heat sink on the processor in my player, I`ve seen that the fan never started at all. The processor was enough cool to trigger the fan ON. But no ventilation inside the player is not a good thing at all. There are another heat sources inside which have to be cooled down. So, I have chose to let the fan running all the time, at a lower speed (disconnected from the control circuit of the main processor). In this way everything become all right: the processor is now running at a much lower temperature than before, the player enclosure get enough ventilation inside, and the noise from the full speed running fan is gone too...
I also mean that in this way should Oppo it self design and implement the cooling system in BDP95...
(PS: By the way, I never used to have may player inside an more or less closed enclosure)
