General informations:
This design born to eliminate the noisy fan of the PSU.
You can keep the original 4010 fan in "pushing" (air direction: from outside to inside) and add an extra 4010 or 4020 fan in “pulling” (air direction: from inside to outside).
This will generate a recirculation of air which will cool all components (Rpi, Board, PSU and stepdown lm2596 if you want install NOCTUA fan, I did it this way)
For better PSU cooling I recommend eliminating the original cover and print this:
“Voxelab Aquila PSU Cover / Meanwell LRS-350-24” by sakrebel (this is a remix of qrrak and ddonnie)
This is the link of stepdown case:
Thanks TC for this design, work perfectly without modification.
To fix the two case, I used the two existing holes on the bottom panel.
