During the month you've been mining, have the cards been sitting on the mobo like in the pic? or connected via risers? and if they've been connected via risers, why are they sitting on the mobo in the pic?
At one point I had the risers on all of them. Then I took them off later since they performed cool without them.
They're not too loud, don't get me wrong, they are a bit loud, but I've had a server that was way louder.
