Oh, yeah. That is one disadvantage compared to the ready made NAS
boxen: noise
Ramon has 3x NMB 120x38mm fans in the Norco for proper cooling of 20
drives + electronics. They are a wee bit loud for home use if you don't
damp the enclosure with foam. The SuperMicro 2U I noted for Sam will
also be loud. Any 2U/3U with hot swap bays will be loud. The fans must
generate high static pressure to pull air through the drive cages and
through the small airflow gaps in the SAS backplane PCB. High pressure
= high noise. There's no free lunch here.
Noise is never a consideration for chassis engineers, as they assume the
box will be installed in a noisy datacenter or server closet.
