Think about where you want your fan's wires to come out before screwing it on. (You can mount the fan duct facing either way on your HotEnd)

Screw the fan onto the fan duct. You may require a lot of torque and will therefore need a well-fitting screwdriver.

Don't worry about getting the screws 100% tightened, you just need to secure the fan.
