Even with the minimum fan speed hacks, I found my SX6012 to be pretty noisy, so I've designed these 3D printable parts to replace the top cover, allowing 120mm fans. With a cheap fan controller, I can set the speeds low enough to be quieter than my PC.
I've put the files on github along with some notes. Basically, just print one of each part (roughly 12 hours of printing on my prusa i3). The three top pieces do require supports under the tabs (print each flat side down). I'm using this fan controller but anything should work.
Caveats:
* It's taller than 1U now, but otherwise the dimensions are the same, so it should still fit if you have rails etc.
* You will have to solder a little bit to power your fan controller
* Be careful of the PSUs when you open the case!
* Due to the pretty optimized airflow of the original setup, my design makes the flow somewhat worse. The goal is that the front fan blows at the CPU heatsink and top of the main PCB, the rear fan blows over the PSUs and under the main PCB (where the switch heatsink is).
* There's less airflow directly out the front, so cooling may be more of a problem if you have any really hot transceivers
* Put guards over the fans if you're tempted to poke the blades!
* It will complain about fan speeds, hope you don't mind a red status LED
Anyway, it's been running nicely for a few weeks. Hope this saves some ears/sanity!
