Hey man, this looks like it might be a solution for me, but I'm really, really concerned about noise. I want to keep the noise level for the chiller down to <30 dB, if possible.. in the video where you were cutting of the shaft..it was really loud- is it always that loud? What, exactly, is making all the noise? If its the fan- couldn't we replace it with some quieter case fans? If its the compressor, can we put some acoustic foam around it or anything? Or would any of that stuff have adverse effects on the system?

Thanks!
