Sheesh, fans set for 100% all the time in the 821 firmware... Anyone played with setting it back to something reasonable like 50% or 20, like I ran the 741's and let the temp circuit moderate the fan speed as needed to keep 90 degrees on the outlet? I guess I'll see what outlet temps I've got first, but my basement this time of year is pretty dang cold, and I'd just as soon trade off some noise if appropriate.
hmm, just looked at the cgminer code. The normal temp on the 821's is set to 70. And even in a cold room, the outlet temps at 100% fan are just at 70 so turning the fan min down isn't going to do anything.... curious
