Extruder and Omnidirectional Filament Cooler 40mm Fan Shroud/Duct

I've created this shroud for my printer's Chinese extruder hot end, I thought it'd be messy using multiple fans so, I tried to make a one fan shroud for cooling both the cold end and the filament out of the nozzle. I haven't printed it yet so I'd like you people to try it out until I get to printing it. My cold end uses 4 screw-on fins for the heat sink.
