Hi Hercek
I've done a couple of prints of the same object (tree frog) with and without the fan. It's definitely better with. The previous effector had three 25mm fans just angled towards the nozzle. No duct. They worked well too but reduced my printable radius. I actually think the single 40mm fan moves more air than the 3 x 25mm fans did. You can definitely feel cool air blowing from the duct on the back of your hand. All in all I like it.
