I am downsizing a hosting business that I’ve had in co-location since the early 00s by moving it into my basement.

Consolidating my own things mainly into one esxi 1u box and a 3u TrueNAS box that are running 24/7. Some customer 4u rack boxes will be coming over as well once I’ve got my stuff migrated up and running fully.

The biggest problem I have right now is the loud high pitched whine of the cooling fans in the 1U as background noise in my house. Fine in a datacenter, not so great for a suburban family dwelling.

Apart from selling off hardware and buying ATX and big chassis for big quiet fans, I’ve seen various images of people’s racks with pizza box servers here and curious what is done for noise reduction.

Thanks
