I did try adding dtoverlay=rpi-poe-plus,i2c to /boot/efi/config.txt but still no sign of fan spinning

I think it has something to do with dtb files because i cant find any of this files with poe in the name

Update:
Nice man on http://chat.fedoraproject.org/ helped me solve this problem and i had to add these lines instead of the one earlier
dtoverlay=rpi-poe-plus
dtoverlay=i2c

and remove /boot/dtb directory here is the explanation:
if you remove the symlink the system will use the dtb thats built into u-boot rather than the one that is provided by the kernel. If I remember correctly you have to use u-boots to be able to use overlays. as the overlay is loaded and then the u-boot is replaced by the one loaded later from the kernel
