I thought nearly all US facilities were air-conditioned to the point that even in summer you need to wear a jacket indoors XD.
I guess if the temperature is regularly over 40°C some air conditioning might be apropriate?
You could always buy a portable AC unit with the cool air directed into the hardware.
Alternatively if your climate exceeds 40°C simply ask about spondoolies long-term hosting solution for US customers...

Spondoolies, did you say something earlier in the thread about running the SP10 at above 35 degrees ambient (spec limit)?
It's per safety requirement. We did test at a much higher temperature of course:https://bitcointalksearch.org/topic/m.5938665
The recommended ambient temperature is 20C
You'll get better results with colder ambient temperature
Update from Benny, our HW engineer:
Last time I was at the safety lab I was told that we can update the Max ambient temperature to 40C.
This is due to the fact that at first the tester used an early FW version. After I updated it, the tester got better results which allowed him to approve the 40C limit.
The are limitations to the max allowed temperature of the top and bottom cover from safety POV.
working in higher ambient temperature than 40C, will make us cross these limits.

so this offer has noting to do with theSP10 at all?
i keep getting confused as to what is on offer and what is not.
Edgar, are you referring to Roadstress's group buy, which is for the 5.4TH/s Yukon?i keep getting confused as to what is on offer and what is not.
which is here: https://bitcointalksearch.org/topic/closed-spondoolies-tech-sp30-pre-order-specs-069gh-046wgh-575499

@Spondoolies-Tech, I realize I'm a little late, but would you like an additional review from a trusted community member? (I do escrows, and I help run a local exchange.)
We don't have miners left from April batch. Really. Only 6 for development and BD purposes.Anyway, we're covered regarding reviews.
Thank you for your offer

Nice story, but I don't know if I should believe a Newbie with one post. 
Thank you for your comment and I understand your skepticism but you will have to take my word for it. I know that’s a hard thing to understand by today’s standards, I’m sad to say. You won’t see me post much, never have before, anywhere for that matter. But if you think about it, if I had a bunch of posts, what would that prove anyway? I felt it was such a unique experience with a company I didn’t know much about and they for sure didn’t know me from anyone. That’s why I wanted to share my experience, I was that impressed with this company, I told them I would write about it and I kept my word to them.

Standard electrical power in the U.S. is delivered in two 110-120V legs, center-tap neutral grounded at the entry to the house. Call the legs A and B, neutral N and ground G. The voltage between A and B is 220-240 VAC, between A and N is 110-120 VAC, and between B and N 110-120 VAC. Typically, stoves, clothes dryers and water heaters are 220-240V. The rest of the house is split between the two legs, for 110-120V to each circuit. Grounded circuits have been required since the late 1970's, so half of the circuits are A-N-G and the other half B-N-G. For a 220-240V circuit, you need A-B-G. For the SP10s I ordered, I installed NEMA 6-15 outlets with A-B-G so I can run them at 240V. See http://en.wikipedia.org/wiki/NEMA_connector for details. This is a routine job for an electrician, because NEMA 6-15 outlets are commonly used for air conditioners. Local hardware stores carry NEMA 6-15 plugs, cords and outlets. A custom cord is required to plug an SP10 in that way. 240V is pretty dangerous, so use a licensed electrician and don't try it yourself unless you know what you are doing.
I am hoping that we will be able to use standard NEMA 6-15 power cords. These work for regular ATX power supplies running at 240V.

Edit: I also remember reading in some other thread about how some forum members did their own wiring and basically re-purposed NEMA 5-15/20 outlets for 240V so they can use regular 120V power cords. I think that this is just asking for trouble.
I took standard ATX power supply cords, cut the plugs off, and put on NEMA 6-15 plugs for use with a 240V outlet. I didn't realize you could get them from Amazon, thanks Soros. All I meant by custom cord is that presumably they ship U.S.-bound SP10's with 120V standard cords. Very excited to get my SP10's!
Read my post earlier, just get the damn 5-15 receptacles. They're the same in term of conducting.
As long as you can make sure NO one ever touch those outlets. Just write a big ass " 220-240V ONLY".
Another thing to remember, its the Amperage that matters , not the Voltage so dont listen to someone who thinks 240V is too much for this wire or receptacle. In fact, for the same wattage, 240v use THINNER conductor (wires).
They carry the NEMA 6-15 wall sockets at my local hardware store. Running 240V to a NEMA 5-15 receptacle is indeed electrically identical - BUT it is also a serious violation of the electrical code and would cause insurance problems in case of an electrical fire or some kind of accident. Just spend the $9 for a NEMA-6 cord and $6 for a NEMA-6 outlet, and properly installed you are completely up to code. I just wish I'd posted sooner, I didn't realize you could just buy a NEMA-6 power strip, so I installed three outlets instead of one.

Nice, with mine, half of them show the maximum target temperature of 113° (crappy 25° temperature intake, changing datacenter soon).
Hopefully the next customer won´t throw his unit in the snow or the company´s deep freezing room, though i might pay for seeing an even higher hashrate

Wow nice 5°C Temperature intake. Thats the whole magic behind pushing these chips to the max. Excellent cooling.
Most datacenters manage only 20-22°C. This shows that proper cooling on these high density rigs goes a long way.

Those are air intake and exhaust temp. Nothing to do with the chips. Under ASIC stats you can see the chips temp. I hope Raskul cand post screenshot of that.
for your peruse-ment good sir...
April 20, 2014, 01:38:25 AM
I know this is intake temperature. It says so in the first sentence of the post...
But intake temperature automatically effects the cooling ability so naturally the chips run cooler at the same speed/power draw and will therefore clock faster.
Also, iceland offers 4ct/kwh electricity rates to their datacenters, fixed for 10 years, some of the lowest on the planet.
Ofcourse we won´t be getting that (+hosting cost +datacenter profit), but it should offer us some nice hosting with excellent cooling.

Iceland hosting is definitely a good idea - even the far north of Scotland would be a good idea (i'm 10 miles south of Edinburgh and all I do it put the rig on the windowsill at a slightly open window. This morning, we have frost (and most other mornings in the year - even height of summer).

It would be so cool (literally) if we (maybe with the help of spondoolies) get enough people together hosting miners in an iceland datacenter.
Bitfury did some research on these back in the FGPA days and i remember the guys (from thor datacenter, iceland?) stating that they could get the temperature in these cotainers to below 10°C,
simply setting them up in the cool iceland air and hooking up enough power.
Excellent cooling combined with cheap (even renewable) power really seems the way to go.
Also, not many datacenters can handle 30kw+ per rack, but this might be a solution.
