I recently picked up a couple 10/40G switches I am enjoying so far.
Arista 7050S-64-R [$160]
Dell X4012 [$150]
I have two of the 7050's in top of rack service:
They are tolerably loud after boot up, {boot is LOUD}
But they are not much over the Dell 12th & 13th Gen server's once running.
{Rack is in basement & can't hear it from upstairs}
The X4012's are great if you only want/need a few 10G ports & quiet.
They are managed, but don't to anything too crazy/fancy.
Had a Proxmox Cluster using one for a while (with Intel X520's) & never had any issues.
Also tried these, but they are way to loud:
Dell S5000 ( great modular switch but needs to be in a data center)
Cisco N5K-C5596UP (not as bad as the Dell, but loud)

Also have these working with cheap 40G LR optics for sub 2km links!
