Anycubic i3 Mega Silent Cooling

thingiverse

Most of the quieting/cooling designs others have made either focus on a bigger fan or isolated cooling to the stepper controllers. I took a different approach to quieting and cooling my i3 MEGA-S by assimilating how rack mount servers channel cool air over the electronic components and evacuate the warm air out the back of the chassis. By doing so, the entire motherboard and components are provided fresh cool air. I replaced the factory fan with a GELID Silent 5 fan which provides ample airflow and is very quiet. Additionally, I had to make a new aluminum case cover to allow for proper air inlet and exhaust. With all the quieting mods I made, the total SPL is about 50-55db when printing. Currently, the linear bearings make the most annoying noise! I've uploaded pictures of my build and will upload the stl files for the printed components in the near future. I will also describe the other modifications I've done to reduce the noise as well as power supply/MOSFET cooling/quieting.
