January 11, 20206 yr I started my unraid journey in october 2019 trying out some stuff before i decided to take the plunge and buy 2 licences (one for backups and one for my daily use). I am working with IT and knowing how much noise rack equipment makes at work i had no plans what so ever to go that route. My first attempt at an unraid build was using a large nanoxia high tower case where i could at max get 23 3.5mm drives into, but once i reached around 15 drives the tempratures started to become a problem. Also what i didn't see was how incredible hot the HBA controllers become. I decided to buy a 24bay 4u chassi to see what i could get away with just using the case and switching out the fan wall with noctua fans and such to reduce the noise levels. I got a 24bay case that supports regular ATX PSU because i know server chassis usually go for 2U psu's to have backups and they sound like jet engines so i wanted none of that. Installing everything in the 24bay 4u chassi the noise levels were almost twice as high compared to the nanoxia high tower case even when i switched the fans out and used some nifty "low noise adapters". Next up was the idea of having a 12U rack that is sound proofed, is it possible? How warm will stuff get? What can i find? I ended up taking a chance and i bought a sound proofed 12u rack from a german company called "Lehmann", it wasn't cheap in any sense but it was definitely worth it! I couldn't possible be happier with my build. From top to bottom: 10gps switch AMD Threadripper WM host server Intel Xeon Unraid server Startech 19" rackmount kvm switch APC UPS with Management Card In total 12u of 12u used! Temps: around 5c higher than room temprature, unraid disks average of 27c. Noise level? around 23db, i can sleep in the same room as the rack! Edited January 11, 20206 yr by je82
January 12, 20206 yr now you're making me want to get off my arse and fix the noise problems in my rack. mostly it's the top mounted fan being a noisy old fart of a blower.
January 12, 20206 yr I bought an isobox studio 20u used on eBay about a year ago and love it for all my stuff. Recently replaced all the fans with Noctua NF-F12 iPPC 3000 and a different fan controller. I keep 1 server plus a workstation computer, jbod enclosure, and a monster 220v backup in it and run about 8-10f more than ambient. The low hum of the fans is glorious vs the whine of the electronics. https://www.soundconstructionsupply.com/isobox-studio/

January 17, 20206 yr I guess this is a link to the "Lehmann" server case. https://www.lehmann-it.eu/en/19-inch-server-cabinets/19-inch-office-racks.html Quick search gave this alternative (80% sound reduction) http://www.msnoise.com/soundproof-it-rackmount-cabinets-4u-6u-12u-25u.html I have no idea of the price. Of course these must be really expensive, reducing sound considerably and be high quality (that's what it looks like at a glance).
January 24, 20206 yr Author I added some leds to the threadripper case (red one), i really don't like leds but i think this one looks sorta neat, damn.... am i one of those people now?
