Mine is pretty darn quiet 🤷♂️
Actually it's quieter than my hp procurve and my Plex server.
You'll want to make sure the 6610 is flashed, configured and running both power supplies. Out of the box it runs at max speed without configuration and if it's missing a PSU it will max the PSU fan to keep the internals cool.
I have a 6610-48p and it's so underrated.
It's one of the cheapest overkill switches we can get right now.
Craft computing did a video on them trashing it because they are license locked to 1G speeds where he failed to mention that serve the home made the fully upgraded license available for free.
Brocade 6610-48p can be had for about $60 + shipping on eBay
They are EOL and server the home has provided all the firmware and licensing for them for free.
