Does your layer fan make a sphere of air focused on the sweet spot?
checkout the video test (radial fan 4020) for aerodynamic and then test yours to see if you use all air output, or just part of it.
This is not "yet another fan duct"
this one is all about efficiency, accuracy, huge vision field.
There is an interesting video for high speed printing test to compare four fanduct models including this one done by ruiraptor:

Source code included (blender files, .obj), no copy rights, just don't sell the files :)
Support:
Hotends:
- E3D
- E3D Titan
- Tevo Stock (chimera single nozzle)
Radial Fans:
- 4020
- 5015
Sensors:
- No sensor
- LJC18A3 (Set X: +49mm, Y: -19mm)
- LJ12A3 (Set X: +49mm, Y: -19mm), it'll fit in LJC18A3 18mm hole, the nuts is bigger
- BLTouch (Set X: +39mm, Y: -21mm)
- SN04
Features:
- Fang design, you can see whats going on while printing, you can reach and remove oozing before they ruin the print.
- Very efficient air blow, minimal curves , no hard angles... to avoid air colliding (air current eliminating)
- SPHERE air concentrating!!! all air blowing focused on nozzle tip, then get reflected to all directions (see the video).
- Balanced air distribution, blow from 2 sides against each other, the air escape from other 2 side, no pushing from one side only, Also Radial fan gives more air at one side of it's output hole, perpendicularly plugging design will split the air current equally for each tube.
- Compatible with E3D, Tevo Stock hotend and many others (please share yours if it fit)
- Support both 4020 and 5015 Radial fan models
- LED holder, very recommended, huge lighting focus, even for dark
Adding LED light:
- buy LED strip
- cut the first 3 led's (cut on line)
- connect wires to hotend fan, red to red and black to black (it'll be always on)
- stick it under hotend fan using silicon bar or super glow, on the fan duct tip, it'll be tilted to direct light to nozzle tip
Note:
- you need to add printing support for sensors edition, select the proper support type so you don't add support inside.
- if you don't have layer fan before, then you might need to put a regular fan very close to bed, to get a first one, with poor quality, then install it and print a better one.
