I thought maybe someone is planning in upgrade their Voxelab Aquila (or Ender 3) the same way as I did, so here is what I did:
I used the original Satsana Model and changed it, so that it now supports the use of two 4010 fans (like noctua - for extra silence), also supports a DirectDrive and can function as base for a cable chain if used. I use it with my Voxelab Aquila, but as I upgraded to DirectDrive it now uses the same mount for fans as an Ender 3. Available for free here:

I used this DirectDrive Upgrade Kit:
UniTak3D Ender 3 Direct Drive Upgrade-Kit Conversion-Halterung für Ender 3 V2, Ender 3 Pro und Voxelab Aquila 3D-Drucker Compatibel with BMG Dual Drive&Bowden Extruder&Dual Gear Extruder(NOT for Neo) https://amzn.eu/d/g7KH2nK
Also I used this fans:
Noctua NF-A4x10 FLX, Leiser Premium-Lüfter, 3-Pin (40x10mm, Braun) https://amzn.eu/d/ff9L8Rv
And this cablechain:

Axial Fans are a bad application for this. Generally you need to limit yourself to around 11 degrees of air “bend” to get good flow. If you have more than that, typically you want a radial (squirrel cage) fan for this as they put out more static pressure. This allows it to overcome the pressure gradients necessary for good flow at the tip of your airflow exit.
You’ll likely experience sub-par performance with this setup. You’ve got good design skills though!
