Epax X10 silent fan setup

thingiverse

Welcome to the first "silent" Epax X10. After receiving my X10, I realized real fast that the thing sounded like a jet engine on takeoff! It was incredibly loud. So, I began by naturally replacing all the fans, which included 2 x 80mm side fans and 2 x 120mm fans that sit on the heat block under the screen. This involved taking much of the electronics apart and soldering in some buck converters once complete, though I was still not satisfied. We designed this setup after 10 iterations of designs, back and forth checking measurements. We finally replaced the dreaded blower motor fan, which even after replacing everything else was in fact the jet engine that created most of the noise. After much research, we found that the blower motor did nothing more than recycle air over the LED array of the X10 and basically push the air around where the side fans would then exhaust the hot air. What we have come up with has replaced a 60mm blower motor with an 80mm Noctua fan, which now takes cool air from the bottom of the X10 air slots and pushes it up to the LED array. The sound difference is insanely lower - I'm talking from jet engine to normal computer. The loudest part on the machine is now the z stepper motor, and that is only when doing long travels under normal printing conditions; it's in effect "silent". All in all, the materials used were: 2 x 80mm be quiet fans 2 x 120mm be quiet fans 1 x 80mm Noctua fan 5 buck converters dropping 24v to 12v Solder, soldering iron, and multimeter FDM printer to print the fan and air channel ducting or someone to do it for you But you could even resin print them, cure them, and then do the work. Also, you can use all the same fans - either Noctua or be quiet; I just happened to have an extra Noctua 80mm lying around and used it for this project. Total time depends on FDM printer and your soldering skills. I can do a detailed write-up or assist anyone trying to do this project if you just shoot me a message - I'm glad to help the community. I have added DB meter from un-modded X10 and video from un-modded X10 as well... total DB drop of roughly 10db Added Gcode file for the CRS10Pro: 1) Use raft to provide higher chance of success 2) Print at .20mm layer height, 60mm/sec 3) In S3D auto support at 60 degrees with support resolution at 3.0mm; in Cura auto-support over 60 degrees Un-modded sound Youyube video: https://www.youtube.com/watch?v=lRFAyjzwKTw&feature=youtu.be Sound with modded fans: https://youtu.be/Z95y6M4AZZg
