This is my setup of 3 S1 outside of home in garden.

https://i.imgur.com/kpDu92h.jpg

They locked in TV cupboard with additional cooling:

https://i.imgur.com/bFgpC9f.png

All 3 drawing 1100w from the wall.

Im using corsair CX500 psu

Extra cooling is made by adding 2 extra fans from old PSU. One blowing in and one blowing out of cupboard:

https://i.imgur.com/RxWnmRD.jpg

Temp of miners on average no more than 40c

So all looks like that:

https://i.imgur.com/Wuon5dn.jpg

Does it not get hot in there?

Btw what w are your corsairs?

I only have one Ant on a 500w Thermaltake, planning on moving its location soon and adding a 500w UPS to it.

As per post im using 3 Cx500 from corsair. Temp inside when i locked no more than 40-45c
I will make extra cooling when will receive more s1 soon. This setup is working like that in this condition for 4 days without fail.

Why would they get hot, they are outside.

Good thinking. That was my plan. Plus the noise of fun is 0-ZERO
Fire hazard if any is outside not inside house.

So everything planned as possible.

Hot weather maybe????

Anyways as long as it's working for you man I am happy.

I too am planning on acquiring more Ants when the price drops more ;)

 

Hot weather is not a problem. As probably to summer all miners will be sold and replaced with more powerfull unit.

My current setup is here.

S1 soon to come.

^sha-256 besides bitcoin are all basically worthless and impractical to mine. Personally, I am planning to mine with my antminers until the bitmain price is in the 1BTC range, then trying to sell them around 1.3-1.5BTC since that seems to be the appropriate markup

here is my rig - 2 antminers and required PSU(s) per crate, plus another antminer on the table behind it.

Wait let me get this clear...

You are waiting for the Antminer price to drop to 1BTC so you can sell yours for 1.3BTC?????

4*S1 - Stable 807 GHs @ 42-44 Celsius
2 Fans on every S1. One in (stock default) One out (added) ... plus some small fans

https://i.imgur.com/822MyQy.jpg?1

Interested in this thread.

Would like to see mods and upgrades that provide better cooling and make it quieter.

Anyone building some kind of rack/housing/mount setup?
I've been brainstorming the optimal placement of the miner and psu that provides best cooling/compactness/modularity.

I only have one Antminer however looking to invest in many more. I have other mining rigs but antminer is by far the quitest one out there here is a vid of me unboxing it.

Version 1.1 of the AntRack, has ~36 ants on it. Still not 100% happy with the airflow and cabling, but its getting closer.

questions about spacing between miners. 

People who have the miners close, are you noticing a lot more heat, than keeping them separate.  I'm in the process of designing my rig.  I currently have 3 right, and I'm picking up 2 more next week.  So i'm trying to get an idea of the spacing.  Thanks

are you blowing hot air into your psu?

You are blowing hot air into power supplies?

Guess I'll fix it :)

Edit: Rearranged it, temps still about the same though.

36 Ants on a rack, I like it, it is tidy too :)

My bday is coming up!
Can I have it? :) (for free I mean)

I know it's not even a long-shot (more like a no-shot), but I doesn't hurt trying  ;D ;)

Btw how much did it cost you in total if you remember?
I know Ants get various prices lately.
Got mine for 2.2 now it's 1.45, but I will wait till Feb 08 to order more.

Good photo

Have you noticed better performance with the blades turn around?

Great photo's these things look crazy  :P imagine someone finding it in 2100+

Very solid machines... hashing at ~400Gh/s... fans added to keep the noise down  ;D

Are you pointing the exhaust from the ants at the intake of the psus? Careful my old pc case which had the psu at the top died from this due to it sucking in the heated air from the two graphics cards below it.

Not the best picture, but I like the green lights. :P

https://i.imgur.com/KsVgQ7j.jpg

Got 4 already in, more on the way, and we want to order even more, but we're waiting to see where the price stabilizes at.

Powered off a 220v 92% efficient Dell server PSU, plugged into a managed switched PDU (we can remotely power cycle any miner at any time).

All of them are pointed to a stratum proxy, on a local VM. Pretty slick setup.

Glad someone else came to the "hm i should label these things" conclusion" :)

What temps are you running?  Overclocked?

I am more interested in how to use a different stratum proxy than the one currently on my 5 Ants.

Ha! Almost all of our equipment has labels, and we have a shared spreadsheet with IP info, PDU plug assignments, overclocks, settings, pool info, API ports, etc.

No, you can't have a copy. ;)

Mild OC, and about mid 40s right now. We're going to add a second fan soon, and then bump up the OC a little more.

My mini rack of two S1's, two Block Cubes, and 1 Chili Miner. All kept pretty cool but looking to add fans on my S1's soon. 3 PSU's one 1000W, one 850W, and one 650W. So far so good and stable.

Fall/winter 2013 til now have been great. My power bill however was not. NYC electricity is NOT cheap.

Two of my six Antminers. I've made custom covers for all of them, which helps force a lot more air over the heat sinks and chips.


http://www.bostick-sullivan.com/images/antminers.jpg

How much did your temps drop?

My brother actually suggested that i should do the same about a week ago.

He said it will work out much better to reduce heat that way.

So, how is it going?

EDIT: Doesn't the hot air coming out from one Ant affect the heat of the other?
I mean because you have them facing the opposite direction.

I usually have them facing the same direction, I just turned one around to take the picture.

I have a IR temp gun and found that without the cover, the chips closest to the fans get up to about 103^F and the chips furthest away get up to 135^F. With the covers on, the chips all seem to settle around 118-122^F. Without the cover the heatsink end gets up to 120-123^F, but the cover brings the heatsink down to 115-118^F.

If people are interested in covers, I am considering making them for sale. I think they would sell for around BTC .018 - .020 depending on exchange. Powder coated .025" aluminum, would include a bottom plate, back cover with cable pass-thru and top cover.

I think you should but you should do it now.
Summer is just around the corner, and when something can help bring the heat down....

Have you considered starting up a group buy and see how that goes?

EDIT: I can start one for you if you want  ;D

When covering my ants I found that it increased the fan speed and it got a little louder  :-\

This is just part of my mining setup...some Bitfury and BFL gear is off-frame to the left.  Each Antminer gets its own power supply.  Both are modular; the first one (on the right) has a 600W Corsair, while the second one (on the left) has a 550W Seasonic.  The Corsair puts both of its PCIe outputs on a single cable, which gets a little warmer than I'd like; the Seasonic uses a cable for each and is a better (if more expensive) choice.

They're on a wire rack in the laundry room.  Connection is through an 8-port switch connected to the LAN through an 85-Mbps (yeah, right!) powerline-networking adapter.  I could possibly clean things up by switching to WiFi: add antennas to the Antminers and a WiFi USB dongle to the Raspberry Pi in the Bitfury rig.  Ventilation is pretty decent; you barely feel some warm air coming from the power supplies, but all of the miners keep the room toasty.  The Kill-a-Watt (not shown, but it's below the picture) says everything's pulling about 1.08 kW.

I keep all of mine in 4U rack mount cases so not much to look at from the front.

Here is the back of a leased pair:

https://i.imgur.com/TCpdpnD.jpg?1

So your psu sucking heat from side of miner?

Yes,

I had thought of isolating everything and sticking three ANT's per chassis.  This setup takes a whole 5 minutes and the miners run at 43-44F so I figured I would leave it alone.  If I need more space I can always stack 3 and vent the PSU above the miners.

Buck Rogers and Street Fighter 2, nice.

LOL

Are there any pc cases that would fit 2 antminer s1 in it? I wanted to know because my Local Datacenter requires it in a enclosure. If any body have any good ideas let me know thanks!

Your local datacenter likely uses 19" racks

Rip out all of the guts including the front and rear panels.

Screw it into the rack.

Good to go.

The short rosewill might work, I haven't used though so check the dimensions.

what are you guys that living in the UK paying for import duties on a single Antminer?

The Cabinet is a G2 HP 42U Cabinet. What kind of Rails do you recommend for this case?

I totally appreciate it, you are a great person! :)

I'm lazy, I usually just screw them into the rack from the front panel.

The rails for these cases are about $20 a shot from newegg.

About £110 on my last order at the end of Feb.

And now for something completely different.

Is it difficult to remove the guts (the internals), is easy to unscrew it and take apart? And what do you mean by ripping out the front and back panel? Do you mean take out the fans harddrive cages?  And by screwing in the front panel to the cabinet will it hold the rosewill case good? Thanks I appreciate your comments.

So when the web interface says 45C, they're really upwards of 80C?

It's a bunch of little screws.

I remove:

The top button panel (power button etc)
The hard drive cages
The metal that holds in the hard drive cages
The rear panel (Pci slots, fan slots PSU mount) it's all one piece
The motherboard tray
The rear support bar/cable tie bar
The inner front panel mesh
The inner front panel mesh holder.

That is all.

They work fine with no rails if you have a full rack.

I suppose if you stick it in the middle of empty rack it may sag a bit.


BadAss.

I put the same fans, 1 on each side and found that at the expense of sound, when OC'ed to 400Mhz, it still runs warmer and doesn't get close to 200Gh/s like the other Ants running the stock fans. Do you have the same results?

The unit in left, my original runs 205 the other 2 run around 195. I dont think its the temps. Some units just OC better its the overcloking facts, some chips perform better.

I got no diffrence when tested each unit with single psu so its no power issue. Some overclock better.

I guess so. I thought the thermal specs on the chips were much lower than 80C.

Question here:
Wouldn't the machine just shut down when it reaches a very high temperature?

I found the best results by placing fans on the outside, blowing on the chips, exactly where the images show they are the hottest: https://bitcointalk.org/index.php?topic=443718.msg4920949#msg4920949

OC @ 400Mhz and HW around 0.6%

I would hope so. GUI still stays under 50C.
These pictures were taken at stock too and were stable for a week.
I OCed them last night and they're still going strong as of right now.
I'll check the temps again. I'm curious to see if they went up at all after a bump to 375.

Just having a look round and managed to group some really nice Ant setups:

I have 4 with 2 fractal 1000 watt platinum psu's and 2 ups units from eaton along with a 16 port switch from trendnet

https://imagizer.imageshack.us/v2/786x590q90/31/i13s.jpg

setup gives 720gh for 1460 watts  and has the ups backup

How much does that actually help with airflow and cooling?  I am seriously considering this, but don't know if it actually helps or is just a bit gimmicky...

it definitely helps. However, there is a tradeoff between the extra fan cost ($15 for a good one with >70cfm) and how much more you will mine by overclocking an extra 5-10GH.

New Update. In my non-climate controlled 2-car garage I have three S1 Antminers overclocked to 393 MHz. The temperature here in Santa Fe, New Mexico is 62F/17C, but the three miners bring the temperature up to a cozy 89F/32C inside the garage. I ran one miner for 8 hours without my custom cover, which then reported temperatures of 54C/57C in the "Miner Status" tab. After 30 minutes with the cover on the temperatures had dropped to 51C/53C, and after 45 minutes the temperatures had dropped to a stable 47C/50C. This equates to a 13 degree Fahrenheit drop on both boards.

I will be selling an improved version of the case within a week, with the price point in the .017 BTC range for quantities under 10, and ~.0155 BTC for 10+ units (based on the current exchange rate). The price will include UPS ground shipping with tracking inside the USA for orders of 10+, while smaller orders will be at a flat rate of .009 BTC for UPS shipping.

Stayed Tuned........

Has anyone tried a liquid-cooling solution? I was thinking it might bring down weight and noise a lot...

I would love to see bitmain do this in the S2.

however, from an end-user POV there are two issues I see:
1) cost of building custom waterblocks is high, probably more then what you would save over air cooling (maybe $25/month) and by getting the extra 5-10GH (~$50), particularly in small quantities
2) you could try immersion cooling similar to asicminer, but the initial costs for that are very high (You would probably need to spend a few thousand in r&d to have one designed for 1TH or so)


In bulk, the prices could be reasonable. I'm sure bitmain could have custom waterblocks made in china that weigh a little more then the current heatsinks for an extra $10 each.

Add in hoses, pumps, and a radiator - you could build a 1TH antminer that takes up about the space of 3 S1 units (weighing about the same as 3 units) and requires only 2 fans on a decent radiator. The final cost might be achievable at a 5% premium over current costs.

I can envision having an antminer where a pair of big waterblocks measuring about 10"x10"x2" (about the size of two of the current heatsinks stacked vertically) could have 4 blades bolted to each it and would only require about the same amount of space as 2 antminers

{[]} {[]}
{[]} {[]}       {,} represent hashing boards    [] represents waterblock
  |\   /|
[radiator]

however, the design costs for this would probably outweigh the benefits up until at least making >100 of them. There would also become the risk of liquids in your mining farm if build quality is lacking or hoses get pulled loose

Best way to lower noise and heat output on these bad boys?

Turn them off.

Best way to mitigate noise/heat while they are hashing at default speeds, my bad it seems I did not clarify.

All them racks of ants make me jelly! how many days to ROI on S1 now-a-days?

You can choose one or the other.

We chose more noise with lower temps over less noise with higher temps. We run the main fan @ 100%, and added a second fan up front that also runs @ 100%. This allows us to OC a little bit, and still maintain lower temps than stock. I also think it helps maintain more consistent, even temps across the board, as I know the difference from one side to the other can be significant.

About 2.5-4.5 months depending how optimistic you are. In all honesty when i got my first batch antminer in (..janruary?) I expected it to be retired in may - now it looks like it will be profitable for another 2-4 months after that.

Its tough to say where difficulty is going, but i think its possible we may see a single-digit change occur in the next month, and may not go past 20% again

Fans on the sides, blowing directly on the chips... this has resulted in much lower temps and fan speeds and much less noise  ;D

Oh sorry.

Enclosures help to focus the airflow.  You could reduce the fan speed/noise that way.  I usually make them louder and make more heat by overclocking :)

LINK to enclosures?

Will this case fit an antminer s1 in it? My purpose is to bring it to datacenter. This case seem like the cheapest I can find. I hope this case work. Let me know.

http://www.newegg.com/Product/Product.aspx?Item=N82E16811148058

ANT is: 135 mm x 155 mm x 300 mm

This case is: 17.75" x 17.5" x 7.0"

Yes it'll fit....   

We have fans out back, and up front, and we actually found that the Ants get better temps if you squish them closer together. I would assume that this has something to do with the airflow over the outside of the boards.

Normally, the fan on the back blows through the side vents, and probably doesn't go anywhere in particular. Well when you have two boards next to each other, and 2 of those fans blowing through the side vents, it does the same thing a case would: direct the airflow over the back of the chips, rather than out into the open air. Then you add 2 fans up front, pulling that moving air over all of the chips, right up the the edge, and it's got to be better.

Most of those shelves are GPUs, but the bottom row has been designated for Ants. You can see the 2 PSUs we have powering all 8 Ants. We have more Ants in another room, but those didn't fit.

How much better are temps when squished together vs putting an enclosure on it, if you know?

what fan did you add for 2nd mount?

We're running both fans @ 100%. We saw ~3C drop when we squished them together as opposed to running them all separate and open.


http://www.newegg.com/Product/Product.aspx?Item=N82E16835200021

Final temps @ 393MHz with both fans @ 100% are anywhere from mid 30s to low 40s, depending on the unit. Most are <40C.

What are the enclosures over the miners? Just sheets of aluminum?

Nice duct setup behind the antminers.

Crov how many Ants do you have bro?

Well since the picture has 6 racks of four, 6*4 = 24, I'd assume 24.

None of this is his. He just uploading photo from other threads.

7 the now - had 14 but sold a few  ;D - Looking to set up AntFarm soon, just waiting on Bitmain getting a shipment ready for the 28nm chips  ::)

Business model on S1 or S2 would be short lived - invest into the latest chips  8)

As Silver said yeah not my photo just put it up here and linked the user in :)

More than happy its a sick rig i must say  :P

It's light sheet of aluminum but it goes all around. 120mm fan at the back of each of these in push/pull setup. Aluminum case keeps ambient temps down.


Thanks. It's a Vortex 475CFM inline fan. Extremely powerful. I have it distributed behind all miners including the KNC and that suspicious looking miner at the top. My guess is I get about 70-75cfm per vent. They all get vented out the window even in -20C.

But do the antminer temps go up?

Yes, by 1C-2C so not much at all. I think temps are going to get higher as it gets warmer outside.

6 x 200 GH/s antMiners in a 4U case, 2-Meanwell RCP-1200 PSUs.. Moving into co-locate this week...  I HOPE, f'ing CyrusOne!

What are your temps like?

^the design is really nice, but what the heck is with the fan setup? you have 3 exhaust fans that are trying to handle the airflow of 6 big delta fans (that are pointed at eachother on top of that?)

The use of the fuse board is neat - I have a few of those with me now but didnt see much benefit in useing them, espescially considering any risk of the open terminals being near so much metal and wiring. (might be worth putting plastic tips on the unused terminals?)

So i got this case and fitted 2 antminer s1 in it. Now i need rail slider, can any body tell which rails to get for this case?  It's kinda heavy with 2 antminer s1 in it so I think I should use rails.

Building a bigger, better anthill now that the weather is getting warm and I cant fit anything else on my limited apartment circuits.

You can see a before-and-after: went from a storage area in the back of an office to what will become a high-capacity rack.

approximately 15kW of power available under 80% rule of thumb, with about 4kW of equipment once I move a few more things in, a bunch more antminers showing up thursday, and leaving lots of room to grow. Not sure what I will hit first - power limits or cooling limits (industrial 600V A/C)

There is a 1200W Corsair PSU, plus 3x 835W server power supplies wired up and ready to go. All of them will use 213V power for a bit better efficiency

The exhaust fans simply redirect the air up and out, they are handling the flow well. They are static at full speed while the antMiner fans vary as need be. The pics with "open" tips was temporary as all 36 spots are utilized in final assembly. This unit is heading for co-location in the morning, but run steady @ 48C in a lab with an ambient temp of 90F. I know NOT happy rack has been delayed, but all will be happy in the morning.

So are you planning to occupy 1-2U of rackspace overhead to get that air out? Im picturing a server rack as best as I can, and generally the airflow is designed to either go out the backside or to go out the sides. If you stacked several of your units, there would be a pretty insane temperature gradient with all the airflow pointed vertically

This unit is going to go into the top of rack where I have a 2U exhaust fan to evacuate it from the rack. Interesting side note between the bitfurys, BFLs, KNC, and the antMiner, the antMiner handles heat the best and I saw a decrease in hash when I reduced their op-temp below 40C.

Thanks to BitMainTech's new 1TH/s this will be the only 6 * S1 unit I build...  well I do have coupons.. ;)

Sure I'll take a pic soon, I tested in my room with 2 antminer s1 in the server case and it overheated and shutdown. Maybe I should just put one in? Maybe If it was a datacenter it would inhale the cold and exhaust the hot air and it wouldn't shutdown? I don't let me know what you guys think of putting 2 in a case. Thanks.

31 S1s in my basement for the winter meant no gas heating bill! The monthly electric bill still gets paid with 3-5 days worth of mining revenue, so I'm pretty happy with this investment.

R1 wow that's impressive. How do you ge the heat out?  I don't see any ductwork anywhere.

How are you moving this heat around your house in winter?

Here's the picture of the Antminer s1's in a Rosewill Server Case.

Does this help temps or noise?

Thanks Pcpoet.

Let them breathe man let them breathe.

That back PCI mounting panel comes out with 8 ish phillips screws and opens the entire back of the case.

Here is a few shots of 2 ants, over clocked to 400MHz (200GH/s). The extra fans you can see are added exhaust fans powered and controlled from the spare port on the 2nd blade.

Something I wanted to note is that when they were moved closer together, the airflow created between them kept them cooler.

In some very unscientific experiments about 2 inches seems to do the trick.

Running happily along at 38C.

Ahhhh very nice looking rig :) Well done R1

Windpath, are those 140mm fans infront?

this is one of the platoons in my army of ants.

Do you find a cooling advantage having the ants stacked on their side ?

The only time I see an issue with cooling is if the fan is not working or on full from the start.... other then that kooling is a non issue so far.

but summer is coming!

You're very welcome :)

Beautiful setup  ;D

I was talking about the Ants ..... NOT  ;D ;D ;D ;D ;D ;D ;D ;D

We have a winner. Going to be really hard to beat this setup.

My first S1, I want mooorreee !!!

https://i.imgur.com/wntf4x1.jpg

I agree, will be very HARD to beat that setup!

Damn that 180 gh/s hashing beast. Move, your in the shot girl xD

That she is  ;D ;D ;D ;D ;D ;D
It is her spot now  ;)

You a lucky dude xD Especially so if she knows what she's standing in front of  ;D

How thew heck are you guys powering so many ants at homes? I have 15a 120v which is about 1800 a circuit. Im throwing breakers right and left...

if you are popping breakers that is REALLY dangerous. Electrical rules state you should keep loads at <80% of the rated capacity, or ~1500W per 15A circuit.

I was using 3 different 15A circuits for a while - just upgraded to some heft 213V, 30A circuits in order to expand

Yeah I moved the antminers to the spare bedroom which is on its own circuit with nothing using it. No problems now. It was in my office walk-in closet which uses the same circuit as my office which has a beefy gaming computer, a server, a laser printer, ect.

When you upgrade to 213V, 30A circuits you need to run new wiring as well correct?

Here's my humble setup.

Keeping my kitchen nice and warm  ;D

You're not popping breakers running 6 Ants through one outlet? In a kitchen with other appliances?

looks like 240V - either a stove outlet of just a 15A 240V outlet that is a little bit too close to its limits

Filling out nicely

^^^ Look awesome...

What is the power consumption?

Here are my Ants powered by a HP DPS-800GB server supply w/ custom breakout board wired to a Raspberry Pi running MinePeon so I can monitor the status and power cycle remotely.

Edit: does anyone know why the embedded image isn't working right?

Nice. How much did that board cost to make?

Roughly $30, I did all the soldering by hand. All in all about half the cost of the CX750's I was using before this.

Any update on this?  I moved my mining operation to the garage to get the heat & noise out of the house, and I suspect it'd benefit from whatever cooling tweaks I can make once summer hits Las Vegas.

http://i.share.pho.to/b1c7bf59_o.jpeg

4 antminer in the crates (soon to be cleaned of dust and relocated to the sheving since they are really loud in comparison) plus a bitfury (260Gh) and S1 on the top shelf, plus 5 more on the middle shelf.

The middleshelf has 3 antminers doing 387.5Mhz using a Corsair AX1200 (1205W on 12v) that barley gets warm on a 213V circuit. one of them is looking a bit over 2% hw errors though and will be tuned back to 375 probably

Its 220V. All my power outlets go trough 16A breakers as that is whats costumary here in Portugal. The watt-meter is reading 2650wt. So there is still margin. This circuit is shared with an A+ refrigerator and 2 other unused outlets.
The oven, dish washer and clothe washer have exclusive breakers.

I gotta say im getting a bit tired of the noise... im gettin some scythe ultra kaze 3000rpm for these babies soon...

16A at 220V is a maximum 3500W. Following safety guidelines for <80% load you should not have a constant draw of more than 2800W on it. If your fridge kicks on that would easily add 300-600W of draw but for a fairly short period of time

Your image is 2.6MB, perhaps that has something to do with it, not exactly sure, try a smaller one.

Nice server PSU hookup btw  ;)

Thanks, re-sizing did the trick!

Each rack consumes 48A @ 208V Single Phase. (24A each PDU) Each PSU powers 6 Ants, each bank of 3 ants is fed with a single 4awg wire (single + and single -) to the distribution block.

Your photoshop skills aren't that impressive :P hehehe

+100

Game over nothing is gonna ever beat this.

This only goes to prove what I have been saying all along, 55nm silicon runs too hot, you have to operate the stuff in your underwear just to keep cool!


It is good to see women getting into IT though :)

Whoa, I didnt know you can hookup AntS1's to a Pi... Do you know of any tutorial for doing this?

I don't think he's actually running a cgminer on the Pi to control the Ants. I think the two Ants are pointed at the Pi, and the Pi acts as a proxy to control the hashrate of both Ants at the same time. It also controls the PSU for easy reboots of the Ants.

I could be wrong, but that's what it looks like he's doing.

I'm lost haha... too much of a noob. It would be great if it was a standalone unit with wifi too :) love anything that can just run on its own, no need for SSH and proxies...

But this looks like a really interesting setup. After my Ants finish their hosting with my vendor, I plan to take them home and start solo mining with them... but if its not possible with a pi, I would maybe just have a small collection of USB AntU1's and U2's solo mining on solopool.com

120mm

Other then needing a PSU, it is standalone and will work with wifi... Plug in, configure web portal (IP,Pool,..), mine!

I see so many people with their ants side mounted & stacked.  What kind of heat do you guys see on the bottom card?  I don't even see a second fan on this rig..which btw is freaking AWESOME!!

I'll beat it all right.

I have mine stacked 4 high.  On the high end, temp wise, i'm at 45C.  I'm overclocked with fans out of the back and two fans sweeping across the blade.  Depending on my weekend, I might do 2 x 2 and see what type of temps I get.

Mine is an outdoor rig on my patio, so I use the bugnet just in case.

I decided.  Blue is my favourite colour.

You guys do realize thats photoshopped right?  Zoom in at that hand! hahaha.

But still is a nice ass.

Wow...  I would definitely do that if I had a house and not an apartment.  How are you managing the heat in the room?

Obv a terminator. 

Wow, that's a lot of AntMiners.

Nice setups gentlemen.

what kind of proof do you want? ill take another pic of her and the antminers =)
perhaps video?

I would like to see as many as you are willing to take.

Seems good, I'll await them :P

We need more proof material!

The Pi just controls the power supply so if something goes wrong and I need to turn the power on and off I can do it remotely.  The ants are super reliable but my last miner was a POS that would without fail break when I was away and need a power cycle.

That said the Ant's have an API I think it would be cool to be able to control multiple Ant's through a single MinePeon via their API.  I was also thinking of building some software to check the difficulty and BTC price and turn the Ant's on and off or adjust the clock rate automatically depending what was profitable under current conditions.

Does anyone know how I can switch between my predefined pools? Either GUI or any other way?

could allow privileged access to the API and have a Linux box sending commands to your S1's

No idea how to get it configured.
