I understand the fees are high but I should still make way more than what is being offered here. I understand the offers and the math behind it. But this machine is still profitable. Just as y'all want to maximize ROI, I want to sell as close as I can to what I have into it. Unfortunately for me I bought it on Amazon for a LOT more than I am selling. But hey, it was fun just doing it. That is, until my wife heard it. 
I have mine out in the garage. The wife can't hear it in the house so she is fine with it out there
I have mine down to just over 50db right now by drawing cooler air directly from outside and venting out of the garage. If possible you might have to move it out of the house. You could also try building a box to muffle the sound down to a manageable level. I find that after I had it running out there a while, my wife doesn't pay much attention to it anymore when she goes out there.
