Gkchpa Member kumar Join Date: Dec 2019 Posts: 33 Rep Power: 6	Hello Everyone, I am looking for techniques for noise reduction in axial fans(cooling) especially in Designing approach (having Serrations on Leading or Trailing Edge ) I am little confused which might bring high overall noise reduction at < 2000RPM. Any suggestion, I am looking for a research paper stating the pros and cons of both. Thank You,
