Fantastic job!!!

Question on the fan noise: With all of those fans doesn't it get loud?
Again very nice work!!!!

Sorry I don't know whats AWG. We use in Europe measure in mm2 for cables (surface of copper in 1wire in cable). That's 3x 1.5mm2 cable.

Yes, all those fans produce a bit of sound, but as You know it's almost impossible to make 100% silent unit ;(.

great looking project there!

and just add 2 6 port fan control units....when not benching...one could reduce the noise level by at least 20 to 50 percent. (on fans only - them compressors are loud enough on their own - )
