LMAO, look at one of my older posts, I knew for a fact this facility would overheat based on what I saw... Little do these guys realize, you need about 150cfm per KW of airflow... That facility @ 1.2mw does not have a 275,000+ cfm worth of airflow through 36'' ducts...

What a joke, the concrete structure makes it a heat trap / chimney.  The white smoke test they did took several minutes to clear out...  We fully cycle our air from intake to exhaust every 6 seconds...  Yeah, so a white smoke test in a properly designed facility @ 100cfm per square foot vacating air allows you to keep your units cool.  And the smoke test, would simply flow from intake, through exhaust, and be 100% clear in less than 10 seconds..

These guys are attempting to condition air, and not move enough of it, leaving them with massive hotspots, and expensive PUE, and a horribly inefficient system..  The only thing you have is .03c per KW/h compared to china's .04 / .05 cents per KW/h

Can't wait until we go public in some of our assets so everyone understands why they can't compete...  I mean, look at Bitfury, they have a facility in Georgia (the country Georgia) directly under a hydro powerplant, paying less than .03c per kw/h, evaporate only, don't have to worry about compressors, and have about 20mw+ of capacity and expanding...

With the changes in heat sink design and methodology as well, you don't even need to treat the air.. You just have to move a lot of air, even if its 90 degrees across the chips rapidly and your fine... At least the direction bitmani is going with there small chip set.

Good luck if you go in this facility.. Why do you think Spoondoolies took one look at the facility and said no way... They decided to go to a different datacenter in Washington and a footprint @ vern global Iceland instead?  Bitcoin miners consist of two groups now, large industrial players, and hobbyist, don't expect to make a dime...  Its a hobby YOU pay for, not get rich on...  You can't compete with my sub 40-50 dollar per KW cost including overhead staffing and cooling...  And the fact that in massive orders, we pay about 50% of what normal people pay for equipment from the manufacturers due to large scale contracts.

If you have free power, and live in a cold place, YES! you can make money, these guys can't even make money if they are by themselves building this facility with compressors and attempting to treat air.  I'm sure the capital for the contractors they used too was excessive as well, that looks like a very expensive facility that can't even run at 60% of its promised capacity during the hot months...  You guys are lucky its cooling down, you'll have 6 months to get your shit together.



I think the problem is some people try to be cheap.  They expect a asic data center to be like a server data center.  They are nothing alike on cooling.   Were talking about a lot more money into cooling. 

Depending on climate evaporation, just massive CFM, etc.  Depending on climate is best cooling method.  But regular AC is never going to be good for asic data centers.   

What happened to this place?
