What's the noise level of this miner ?
loud !!! but you can put in quiet fans but make sure they at least do 181 fpm or better if you do . and there are some very quiet fans that can do that . mine has two of the loud stock fans in it still ,I left in to be safe , i replaced the others fans with quiet high air flow fans. lets say if you don't do some kind 0f fan mode it is a data center loud , i can leave mine on all nite in my house in another room and no one is bothered by it but before with all fans @stock it was bad . you can't sleep in the same room either unless it's winter time, if you can get it quiet enough, it gets to hot with the stock fans or not, the cooling really sucks on these miners but there beasts if you can keep them cool which you can:).I would use this firmware update

if they over heat with that firmware they shut down and don't burn up , at least mine did form testing they stop hashing after 12 mins tops, if they over heat and then don't hash till you cool them off, i intentionally over heated mine after the firm update.
Run wires from each board to the PSU don't use the patch wire in between the miner and PSU it may burn out a board or worse start a fire. use 16 GW or better wire to power it. if you use 16 GW wire a 6 pin PCI plug is fine, if you use 18 GW you need a 8 pin plug.
I know it says AlcheMiner but all these are is a version of the AlcheMiner miners same chips and boards . controller fans etc ..
Just giving a few facts about these miners they are very nice, but set it up right, once you have it.
