Quieter fans for the L3+ from Antminer?

These videos should give you all you need to know about this, it is a playlist I made on Youtube has a lot about this: Handling Mining Noise at Home

I would consider purchasing some duct work to silence the machines a bit, you can get to 65 db, most machine are around 75 db so a reduction to 65 is significant but you will likely still hear it. You can save yourself a lot in materials by finding a place that you can just let it run, not an option for everyone though.

don’t ever change the original fans, if a fan dies only buy the same original fan replacement. all other fans are inferior!
