@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 Smiley

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://bitcointalk.org/index.php?topic=521520.msg5938665#msg5938665

The recommended ambient temperature is 20C
You'll get better results with colder ambient temprature

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.

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...

Yes. 40°C is the maximum allowed ambient temperature from safety standpoint.

If, for some unknown reason, someone intend to operate his miner at above 40°C ambient temperature (say, some days in the summer in Israel without AC) we can update the firmware to allow it, at the expanse of hash-rate

These have served me well -- downside is they pull about 1300W at the wall.

The power needed to cool a certain unit is typically 1/3 of the units´power.
Therefore, an AC that draws 1,3kw should easily be able to cool 2 sp10s or 1 sp30.
You can also try directing the cool air flow by placing the units very near the AC or by creating some kind of funnel (warning, this can be a safety hazard)

I forgot wether Edgard was asking about sp10 or sp30, but for the sake of thermal argument, 2sp10 shall now equal 1 sp30.

Got 3 racks of various miners, KNCs, Bitmain S1s and SP-10s.

The SP-10 is the most professional product I have seen any company develop, this is what I expect when paying what amounts to many years of salary to just get one piece of technology.

No way would Dell, IBM, etc would release a server that they did not actually custom build.  Now with KnC the BTC difficulty was low enough that all October and November orders ROI in Bitcoins was very real and possible.  That is the point, to mine in order to get more BTC than spent otherwise we should just keep the BTC until the price goes up. 

For those that think ROI is part of the expected BTC price increase then they are not looking at reality.  In fact John from HF told me, (B1 buyer, burned very bad), "Look at the price of BTC now!  When we deliver your machines (said in early December 2013) which is estimated to be in just 2 weeks! (Direct LIE) that the price of BTC being so high you will make your money back because the value of bitcoins has gone up so much.  (again Btc in < than Btc out is True ROI even if btc went back to $1)".  Then to add a cherry to the top he said, "We will ship your MPP cards with your order, guaranteed!" I think John needed to lay off the coke.

Anyway, this level of professionally produced machines are what I expect when spending 50-75k in an order. 

KnC got a pass on very bare bone cases and miners because they were able to come out before everyone else with higher such a high GH per machine and also the best Gh/Kw at the wall at the time plus KISS with their product.  That meant that who ever had any of their Oct-Nov batch has already made more BTC than they paid in just 3 months, especially since Hashfast didn't deliver and raise the difficulty same with CoinTerra delivering late and under spec.  KnC could have shipped a cardboard case and people wouldn't care, they only wanted that hashing power since there was nothing in comparison on the market at that time and only delivered 1 week late (I know, KnC is different now).

Back then "home/hobby" miners could get a few of those miners (with the extra hash power at near 550gh) and it was still viable for a home setup.

Of course I hope the best with Spondoolies and really want to count on them to be a truly honest and moral company but now the home miners need to have a lot more capital or other funding otherwise or DC hosting as normal houses will not be able to run even 1 Neptune or one SP30 without major upgrades to 220-240v.  At that point, heat is a large issue, normal house AC will not be able to handle all the heat.

So for a "home rig" to be profitable, power has to be cheap, cooling has to be efficient and cheap, issues of sound and air flow must be taken into consideration and at least more than 1 or 2 miners, you would need more like 5 SP10 and 5 SP30 to really even make a dent in the difficulty and make all the extra work and cost of installing infrastructure worth the return on mining.

At this point having 1th of mining is not to different than 2 BFL Jalapeno running at ~10Gh in total which made about 2-3 BTC back when they finally delivered.  Since no other Asic companies had made large deliveries even the almost 1 year late BFL machine made BTC ROI in about 2 months.

Now 1Th won't generate a single BTC for a week or more, you need more like 10Th to even get close to 1 btc a day.

So I hope Spondoolies changes the playing field and lets people get back in the game.  Only thing is the heat that these generate from the bottom, I would rather have a 2u unit and more heat sinks stronger fans or I still have to keep them about 4u apart from each other because of the heat.  Even if I attach a copper cooling plate with a closed loop R134 coolant and compressor that would cost about $300 per plate, setup for the copper and more power to run the compressor.

Just my 2c, keep up the good work though.

Timmah,

Appreciate that review/comment...

I too have felt the 1.25u is a mis-step in design.  4u would have been much better.

 - Not many DC's can handle > 12kW per rack
 - 120mm vs 40mm fans (improved cooling and lower noise)
 - Potential for ATX PSUs (easier for user replacement)

I was not aware that the heat issues were as severe as noted.  I planned to not have more than 8 per rack as well (<12kW).

- The DC´s with really competetive electricity can also handle a good power density. With this you have the choice of a high density data center or just using only some of your rack in a low density environment
   (also, smaller DCs might be able to give you an attractive rate by only charging you for one server and power use, and put the unit into a shared rack that isn´t maxed out yet)

- The whiny, high pitch sound of 40mm fans will be replaced by a different sound in the sp30 (80mm fans)
   Using a bigger case makes it more difficult to move the air through the heatsinks, much of it would flow around it. With a small case you force nearly all air through the heatsink, making for efficient cooling.

- Many times, used replacement server PSUs can be picked up cheaply if one of yours dies, however this should be covered by the initial warranty. PSUs are typically designed to last for ~5 years

There are always both negative and positive points about design and implementation choices.
You should especially check before setting this unit up adjacent to your bedroom, but the noise level is mentioned in the unit stats.

For DC with "regular" power and heat density, 8 units per rack is indeed make sense. There is no need to space them 4U apart, but since the rack can only provide 12KW, it doesn't change anything.
Our own high density data center can handle up to 32 units per rack.

The SP30s can't be run at home without modification to the electrical system right?  I have a 110V system now. What changes would i have to get an electrician to make that would allow me to run 1-4 of these babies at home?

Hoping to get some input from Spondoolies-Tech or knowledgeable members.

Thanks.
Only an electrician can truthfully answer your question after doing a brief inspection.

In the USA the 3-phase power (A,B,C) is most often distributed as an equivalent 6-phase power (A,-A,B,-B,C,-C) when each of the residential hookups gets a matching pair of (A,-A), (B,-B) or (C,-C). So you may already have 220V power although all your outlets are 110V. Even the wiring may be already there, but just the outlet wall plates are 110V to avoid confusion or mistakes.

Places where the power is really true single-phase 110V are comparatively rare.

You'll have to ask an licensed electrician, because frequently even the owners of premises don't know the real situation. You could also ask your electric utility representative over the phone, but sometimes they don't have the real, up-to-date information, since their responsibility ends at the panel with the power meter.

Edit: Here's a more detailed explanation http://en.wikipedia.org/wiki/Split-phase_electric_power . For your own safety, you shouldn't ask non-Northern-Americans for advice about the electric hookups. Even well-meaning, educated people may be unfamiliar with the historical quirks in the North-American Electrical Code that date all the way back to Thomas Alva Edison.


I want to thank everyone that responded to my questions, I've got plenty of good info to read. Smiley Thanks again.

Nice story, but I don't know if I should believe a Newbie with one post.  Cheesy

What's not to believe in his post? That he got the unit earlier? This was already stated by me too and by some other members. That Spondoolies Tech was very helpful and prompt? Anything else?

Of course I hope the best with Spondoolies and really want to count on them to be a truly honest and moral company but now the home miners need to have a lot more capital or other funding otherwise or DC hosting as normal houses will not be able to run even 1 Neptune or one SP30 without major upgrades to 220-240v.  At that point, heat is a large issue, normal house AC will not be able to handle all the heat.

Spondoolies said they are trying to get a good DC deal for their customers so they already got that covered.

and

the marketing world does not start and stop at bctalk, i'm sure Spondoolies-Tech have made sales from folks right over the world who don't stop to read the trollfest that this forum has become... this really irks me (we were all there at one time) just because someone hasn't been logged in / registered for a long period of time, it doesn't make them lack of intellect.
