My parts cooling fan has 2 short and 2 long screws. The small black skinny ones. The design made it appear the same screw that holds in the parts cooling fan, holds the nozzle to the right side as well. Your saying a second screw goes in behind that screw but slightly above it?
The front, larger cooler fan worked with no issue. Not sure which screw size those are though but they are silver, and have a rounded head.
