Dual 40mm Fans to single 40mm
thingiverse
I prefer fangs for cooling, but I didn't like single blowers or dual blowers since they're too loud. I've seen dual blowers to a single 40mm fan mount but no dual 40mm fans. Here's my remedy. I use 40x20 Noctua Fans - https://www.amazon.com/gp/product/B071W93333/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1 You'll need an M3-0.5 Tap to tap the holes for mounting the fans. Screw sizes are crucial: M3x15 for a 10mm thick fan, and M3x25 for a 20mm thick fan. Note: There's a rogue bridge within the STL that I'm currently investigating; for now, you can cut it off and fill any holes with super glue.
