anyway to quiet down the S7's fans?
I don't know if its normal or not, I have 4680/4200 RPM @ 53C/54C/52C @ 675Hz 4.56GH/s
Put the S7 in to a soundproof cabinet like I did or underclock it and reduce the fan speed.
What does your sound proof cabinet consist of? still need a lot of air flow to keep it cool and fresh cool air in
