Problem Solved!!! The original fan sits in between the fan duct and the red metal plate the serves as a base for the extruder. The narrow gap between the fan and the read metal plate limits the amout of air being able to be sucked into the fan wich results a very low air flow comming out of the original fan duct, wich of course leads to poor filament cooling. This Design switches The mounting position between the fan and fan duct resulting in a free air flow being able to be sucked into the fan and out of the fan duct. The Design uses the original fan and screws so there is no need to add any extra elements or materials except of printing the new fan duct. Printed Upside Down with the fan Hole facing up and with NO Supports Its a SImple and Powerfull Solution.
