Built this boi to mine gold. Was a personal challenge to rig something up in a milk crate, and it came out quite nicely.
Not loud enough to keep me up at night, but I keep fans above 60% to keep temps around 60c.
The Zotac 1080 TI runs at 75% fan speed and I can hardly hear it. The Zotac 1060 mini runs at leas 6cs hotter than everything else, so I have that fan boosted. The EVGA 1080 TI runs a bit cooler now that I have that external fan blowing into it, but its fans have quite a bit of hum at 65%.
Been experimenting with different power draws. I've been keeping the 1060 at about 80% power to help combat its temps and still maintain about the same hashing power. everything else is at least at 95% power.
