Fan speed constantly at 100%, nvidia-smi and nvidia-settings report wrong values.

My card is an MSI GTX 780.

As soon nvidia-persistanced or xorg starts up the fan on my card spins up to 100% and stays there forever. nvidia-settings will fail to report fan speed at all and displays 0% while nvidia-smi displays 35%~ which is clearly not correct either.

I’ve tried downgrading but have found no version where it works properly.

Edit: I suppose I should add that it works fine in windows and that the open-source nouveau driver is able to control the fanspeed of this card just fine.
