It's not too bad but I have it out in my garage so the sound and the heat are not an issue. As a matter of fact I can heat the better part of the garage with just those three GPU's running. But I also have in that same room three more computers. 2 are mining Monero and one is a dual node server I am currently building out as a STEEM SEED server and my backup Witness server.

But I am going to have to wait to deploy them both for production. I was not happy with the performance so I ordered the fastest CPU's those dual boards will take, 3.4 GHz Woodcrest and a better performing ECC DDR2 RAM.

so my SEED and Witness servers won't be racked until end of the first week in Feburary. (sad face)
