The duct is meant to be adjusted to each setup. It is NOT meant to be pushed to the top. The correct setting for your setup (any setup) is to have the bottom of the cooling duct tips to be between 1.0mm and 2.0mm above the bed surface when the nozzle tip is touching the bed. The typical optimum is between 1.2mm and 1.4mm, but yours may be different. It depends on the size of the hot-end and the height of the nozzle tip. From your photo, you have your duct mounted too high. The slots in the duct mount peg and holes in the sides of the base allow for a very wide height adjustment, and by small amounts.
