this^^^

were i live it can get to 20* below  , i feed my miners filtered air from outside in the winter , if u need to power off and power the miner back on in that kind of temp it usually wont restart.

last winter i had to keep a hair dryer in my datacenter for restarting miners when it got cold out , oddly enough the  only ones i had issues with were the miners that used the beagle bone controllers , all the s3;s would start right up no matter how cold , for this winter i have restricted the fresh air intakes a bit to keep the miners warmer , and all is good , though our coldest night so far was only 2*


as mentioned s7 and s9 miners do not like to run very cold, so if u have those u may have issues,, spondoolies gear absolutely loved the cold , infact im still runing a bunch of sp20 and sp31's, older miners like the s1/s3/s4/s5 walso ran just fine in the very cold temps , with the exception of restart issues on the s4 and s5's , warming up the controllers with a hair dryer on low solved that issues though if they wouldnt boot up on there own


i dont expect any issues this year though with the restricted air intakes  and the fact i have alot more gear now and it keeps the building decently warm

Still available to manage Canada group buy if need be! 

sound levels

from about four feet. 

this is not as quiet as a sidehack modded s7-ln
this is not as quiet as an avalon 4.1 that is downvolted and under clocked.

In my friends office it is fine
It is definitely quieter then the avalon 721.

Tentative pricing for a Bitfury 16nm pod is around $125. My reseller friends are worried that >$100 is too much for a pod miner. With an estimated stock setting of about 650GH at 75W DC, would folks still buy it? That's priced high even by Avalon721 standards, but it also has better efficiency - and with integrated undervolting, it can get better still.
