Corsi-Rosenthal Box Fan Panels For Noctua NF-A20
Print Profile(1)
Description
Noctua NF-A20 Corsi-Rosenthal box panels.
Printed with PLA with 3 walls. Shouldn't need much more than that to hold it together. Increase materials and strength to suit your needs. I wouldn't set anything on top of it or trust a pet to not crack the top.
Printed parts:
2x A panel
2x B panel
1x Middle Bracket
4x support Bar
4x feet (Any way to lift it will do. Basic feed included)
4x fan grilles (Optional, not provided)
Non-Printed parts:
5x 20x20x1 filters (Modeled to 19.5 x 19.5 x 0.75 dimensions)
4x Noctua NF-A20 (PWM or 3-pin of your choice)
1x fan power supply for 4x 3 or 4 pin PC fans. I used Delinx 36W fan speed controller.
1x roll of duct tape
1x roll of 1/32 gasket material
16x PC fan screws
Assembly and notes:
Seal in between the fans and each panel by cutting thin strips of gasket material.
Seal in between each panel on the inside with tape.
Install gasket material on each panel edge where the filters go.
Screw in fans in an orientation that allows you to run the cables to one side. Add in support bars while doing this.
Secure the speed controller cables and fan connectors together how you see fit. I used zip ties.
Screw panels together with support bar interlocks.
Install 5x filters.
Filters are basically an exact fit. They take a little persuasion to install but should squeeze into the edges.
Tape all seams with duct tape.
Run the speed controller cable out the bottom edge and seal with tape.
Add feet of your choice.
Run unit.
Pros:
Quieter than an average PC.
Frame lets you line up and tape together filters easier.
Takes almost no power.
Printable with cheap materials.
Cons:
Top panel is not built for anything other than fans.
Would not trust it to hold pets or anything sat on top.
Replacing filters and servicing electronics requires re-taping.
Only printable on H2 or similar size printers at this time.
The fans screwed in do not "squish" the gasket material down. It looks to be sealed well enough to not be an issue but don't screw the screws down too tight or the panel will flex away from the gasket.
