My power is less then .001 cents per KWH, maybe even cheaper.

Who are you ripping off? Alternatively, if it truly is a free source, how many KW is it limited to?  In that case it will still be wasteful to A/C vs. fan, because you could have purchased extra miners and used the energy to make more BTC.

If its truly free and unlimited then why are you wasting your time posting on this forum?   Shocked

His user name is MCHouston. So may be he is in Houston, a hot area. So fan might not work.

Have you read this? ---> http://www.coindesk.com/cryptocurrency-miners-turn-exotic-cooling-systems-competition-heats/
It's more targeted at data centers, but they say liquid immersion cooling systems are becoming more common these days.

Very interesting concept and could cut cost in cooling.  Grin

LOL that is too hardcore for a house.

1 BTU/hr = 0.29307107 W. It does not matter what the application is that consumed the watts and produced heat in the form of BTU/hr.

Thanks for the info. So 5.5-6 tons of cooling if I max the breakers.

Cooling ganna cost you a lot, better to just use fan?

Fans definitely will not be enough for this much heat.  This is more heat then an outdoor gas grill. I should be fine, you can buy used 5 ton cooling units for around $3000.
You are completely confused.  Don't even think about attempting this.  It won't work.  You can't AC miners.  You must blow the heat into the atmosphere with a fan.  If you attempt to use AC, you are going to be stunned how much energy you will consume.  It's not engineering, it's physics.  

Nope not confused. Of course you can AC miners, how do you think large datacenters do it?  Fans are not a viable option as Houston has 99F+ degree days with 80%+ Humidity.  I may be able to do a hybrid and AC outdoor air to below 80F and pipe it in for the miner intakes the exhaust outside, but that is a lot of ducting.  Full blown ACing them still seems like the best option.

nice price

Awesome price. With that, maybe you should consider renting out space for other people's mining units...

How so cheap?

LOL maybe. Depends if I run out of funds to buy miners, and also if I get my 400A service feed. I provided my load analysis on Friday, so I am hoping for good news this week.

Not ripping off anyone it is a 12 month electricity contract offered by one of my local power companies.  My price per Kwh goes down the more I use so that no matter what I always pay the same price a month.

Good point on more power for miners problem is I don't think they can survive operating in spring/summer in Houston.

I do not move in for 3 weeks. currently stock piling equipment. Got miners, PDUs, servers, PSUs, and other supporting infrastructure just waiting for me to move in.

I am new to these mining things and i want to know that, "What if the difficulty level increase?, would i make a loss with mining? I am mining $1 USD with 5MH/s server with the current difficulty."

When the difficulty rise, your income will be lower.

The trick is to vent the heat from the miners. I use a triplite 42U enclosure with the thermduct kit it works fan-tastic Smiley I use an 8" cyclone fan to exhaust the heat from the cabinet up into the attic where it goes out thru the roof vents easy peasy...
This setup prevents the miners from continually heating up the room air and even if the room (garage) gets up to into the upper 90's F its still effectively cooling components running at 43C to 50C (109F to 122F) antminers or the Jupiters that run around 65C (149F)

Smart guy here lol Im doing the same thing did u need a in line duct fan or just run it up and out?

Funny someone responded to my thread today, I actually had a heat problem this weekend. so much heat is being generated by my 35Th that is pre tripped the breakers on my 30a PDUs. I may venture to say heat dissipation will be my limiting factor at home and not my power.

Grabbing popcorn...

This is going to be good!  "Signs lease with precalculated power cost"  then you want to "add 90A @ 220V of miners".

LOL

So this landowner is just going to roll over with a $2K/month power bill?

And to answer the original question, as others have said you don't really want to cool the air, just MOVE the air from outside>in>out. 

I ran 5KW of miners in a 2 car garage during 100 degree summer days it was 115 in the garage but the S1s have some fan headroom so it worked out  Wink

Why would the landlord care?  My power company is the one the contract is with.  Remember what they say about assume, I never said my electricity was provided by my landlord.

Also I am a bit passed the 5KW mark, more like approaching the 30KW.  5-15KW was easy once you go >20KW thats when you start finding other issues.

well i do pareciate you guys to be in the calculations of mining even teh temperature and watts consumpiton but you must realise that diff will rise so roi of 3 months will be roi of 6 months in a jiff i mean ant miners for TH will give only 0.07000000 BTC per day and thats like 3 dollars per day a TH it neeed like 180 days to 240 days to roi i supouse.
