try to set the fans to 30% rpm before "frankensteining" one of these awesome switches ._.
Welp, still too load for me. At 30cm the noise is 41db. My whole 32U rack is 31db with 3 servers (water cooling with 6x low RPM noctua + a few EXOS&WD GOLD HDD) and 1980 (with noctua)

replacing my non S, with S to reduce power draw, wish me luck!

I find the arista very compliant at 30% fan! love the feature.

you could do noctua cardboard mod as well though

Now I have modified it with Noctua fans, but I didn't liked that that temp of front sensors were around 60 degree, so I added two small (30x30x15) fans right near the big heatsink with Noctua noise reduction, now it's not louder, but cooler.

If you found this post and you planning to modify DX7050SX-s with 495W powersupply

They using different colors for PWM and Sense in PSU


The correct color for PSU is
  • Ground: Arista Black = Noctua Black
  • +12V: Arista Red = Noctua Yellow
  • RPM: Arista Light Blue = Noctua Green
  • PWM: Arista Yellow = Noctua Blue
Learned that hard way
