Summary	0001899: 5 fans present on IT8728F, while only 3 speeds visible of which only 2 controllable
Description	SpeedFan shows and correctly reports rpm of all 5 fans sockets available on my mobo. However, I only have 3 speeds. 01 and 02 work fine but I can't control speed03 (labeled as power fan on the mobo). Is it a hardware limitation?
