How can i reduce the noise?
does the L3+ really work with 75 db?
i have no garage, i will use a room which is inhabited, but the neighbour have their bedroom under this room...
i read that the fans are not so noisy, its more the air which is sent out...
how can i reduce the noise?
I start to mine with the L3+ tomorrow...
and i want to build up a "Little Home Farm" with 5-10 pieces of L3+ Miners...
My Mathematics is good (so don´t talk with me about the costs

)
I just need good tipps for the noise of 75 db...

From what I understand the pitch can be heard very well through drywall. I would try putting sound proof foam around it but so as to not impede the smooth airflow the miner needs.
Another option I've seen done will not likely void your warranty: Removing the stock fans and putting silent ones in like these
