E92 ventilation

I've notice the cabin fans run as a fairly high speed for what seams like little difference between cabin and outside temperature.

EG
Set to auto, AC off.

Set temp 17° outside temp 16°. The fan speed bar is three quarters along, which seams high for 1° if difference.

Anyone?

I notice the same for me, though mine is set at 21C, there will be a huge amount of heat coming into the cabin and fan speed will never slow down. If I do the same with the AC button on it'll warm cabin up quick but will back the speed off to very low once its at the right temp. It controls the temp only in AC mode?

I think I've sussed the problem with mine. I had the rear seat passenger vents closed. After opening them I noticed within a couple of minutes the fan backed off to a normal level, once the cabin reached the set temp.

With AC off? Might check mine this weekend to see if the same happens. It might be that my temperature is set too high as well and it really hasn't reached that temperature. Strange that AC button on for me backs off within 10 mins...
