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:

Also I used this fans:

Noctua NF-A4x10 FLX, Leiser Premium-Lüfter, 3-Pin (40x10mm, Braun) https://amzn.eu/d/ff9L8Rv

And this cablechain:
