I'll say it can. I have a Startech 12U on wheels with a Norco RPC 4224 holding 24 disks + a Supermicro 2U that holds a Intel J1900 working as FW/VPN. The Norco rests on a 12cm polyurethane mattress on the bottom with no metal connection (not bolted) except earth wires to rack. The matress is earted as well with two metal rods in them (static can be generated from polyurethane mattresses).
I have modifed the fan wall on the Norco and fitted 3 Noctua NF-a14 IndustrialPPC 3000 Fans + sealed it to force all air through the fans. In front of Norco chassis I have mounted 2 x 900rpm 180mm fans to push in air through the HDD caddys. I also make use of the underpressure in apartment with that I sealed off the space behind door in front of chassies and where I force feed the air directly from central ventilation through the chassis on top and out in the back.
2x 2670 v1, 2x Noctua NH-U9S, Intel S2600CP2J, and 100+TB of storage dead silent. When transcoding is done I rarely just can hear the Noctua 3000 fans rev up but 99% of time my laptop makes more noice (sitting 2 meters from rack). HDD's constantly in low 30's C.
Sorry for hijacking but I thought it could be useful if OP perhaps considered to build something. Feel free to holla and I will delete my post or put up elsewhere..
