BOX silencer for inline fan

  1. Currently working on making a box as a silencer for a 4"inline. Had it on bungee's but it was still too loud. Do I need to worry about it CATCHING FIRE?? Does it work at all, if anyone has tried something like this?

    Here's an example: https://www.icmag.com/ic/showthread.php?t=180399
     
  2. Common someone has to know something about this!
