Does this produce lots of heat or noise? As the heat and noise have been problems for me in the past..

Not sure if anyone else is noticing this, but my S2 doesn't seem to like the cold. My pool hashrate seems to drop when the boards are mostly below 500 and when I close the door to the room and let them heat up a little, the hashrate increases.
This seems to be opposite to the S1's which seem to run better in the cold than the hot, which probably has to do with the underclocking of the S2.

Hey Bitmain I paid for 1 S2 unit and it still shows unpaid. Order ID is 00120140605015229471lqbSxY0N06D3. Please confirm that this paid and that the unit will ship in the 48 hour window. Thanks.
People can debate it to the end of time.. Bitmain HAS the better buy ! I looked at Spondoolie and considered a purchase from them but here is one fact that you can not get around … Spondoolie builds a more solid machine NO DOUBT, however these machines have a life cycle of about 9 to 10 months max. In two years 99% of these machines will be boat anchors, so a MORE SOLID machine is not going to get you ANYWHERE ! Bitmain builds the machine that is going to get the job done at the lowest cost for the amount of time that the machine will be "in the game" . It's that simple ...
When people say that the rig is pulling 1050 they mean using their watt-o-meter, all the slightly lower efficiency means is that it pulls a few Watts more from the wall.
1050 watts at the wall in the case of the PSU on the S2 would mean its probably providing 916W to the miner (87.3% efficient) in fact in order to provide 1000W to the miner it would be pulling 1154W from the wall
My kill-a-watt reports just on ~ 9 amps on a US 120v circuit for the S2, when cranking ….
9A @ 120V = 1080W
9A @ 110V = 990W
I thought the US was on 110v?
The most common pair is 120/240 bit there is 110/220. Actual voltage at outlet can vary 3-5% because of other factors like distance and wire size as the power is delivered to the house.

mine took from the 25th to the 4th to arrive busted up - and the whole journey is only about 1000miles with 99% of it in the air.
now im trying to get a replacement board & clarification if the power board/boards with missing & broken caps are safe to run and bitmain insists on asking me to try again, and again, and again and reapply thermal paste and try again.
one DEAD board is much less than i expected from the state it is in - but the enquiry as to if it is safe to run or not has thus far been ignored half a dozen times.
I know that happens a lot, but the shipper needs to take some level of responsibility on that. Yes Bitmain could pack better, but they have made changes on their end to try and mitigate damage in shipping, however at the end of the day if UPS drop kicks your package to the door, you're going to have issues.. I'm sorry you had issues, but if I was in your position I would do this … get the unit running and hashing with one main control board, and one of the GOOD hashing boards.. After that add cards to the back plain starting with the LEAST damaged cards first. Each time, see that the unit powers and identifies the card . If it makes you feel better, don't put the cards that have damaged caps in.. but I would at least try to get the unit hashing on some level.. There are a lot of tricks to the S2 unit so take it slow . In the back ground, continue to work out issues with Bitmain. I have worked with their support, and believe it or not they DO want to help, most of the time they can resolve the issue so that you have a fully working unit . Bitmain is one of the only vendors I can say that about .. I'm sure their are more who do a good job, but its risky to try out new vendors at these prices .. It's a large investment .

Either do it WITH discounts or do it WITHOUT, I provided both. Using a discount on the S2 and none on SP10 makes your figures wrong.
And as I said earlier, I'm not cheerleading either, the A1's beat both.
You normally get 1450 GH on sp10s, so you should probably calculate with that.
In what mining pool SP-10 get a really this speed?
The upgrade Could be another half step up with new boards with more chips and under volted more. That's why they leave psu to customer.
Next next phase is newer chip design?
Next next phase is newer chip design?
I don't see how this saves a lot of money if you need all new boards and chips. Only the motherboard is reused??
I think that will come only new boards, without Heat Sink.
Did I miss something ? Is there a delay on shipping for batch 4 ? My unit has been paid for, the status shows paid and valid, however after two days it still shows unshipped .. These delays are KILLING me on making a return on my investment Bitmain … This is not my first order, and my account clearly shows I am a return customer.. Whats up guys? To much sauce from the holiday ? 
Had this order shipped on the day it was paid for I would have had it by friday, now I won't get it until Monday / Tuesday at the soonest.. That is a four day loss in revenue minimum . HELP PLEASE ...

You also get around 0,85 - 0,9W/GH on sp10s, compared to 1,1W/GHs with s2s.
I have to agree that it will probably only save you around 10-20% when you will be able to switch out the blades, as the only savings are in not having to buy another PSU and motherboard.
Oh, sp10s come with PSUs and readily assembled, compared to the "new" S2 kits.

when I bought some of the S2 , every time I got the coupon. Bitmaintech writes- Returning customers please check your account for coupons.
Spondoolies-Tech gave me a 5% coupon, which could not be used.
I do not ever buy any of the SP-10 . I sold the SP10 , and I am happy . The ears are resting.
Hashing 1.48TH/s which shows the SP-10, eligius and btcguild haschrate was barely 1380GH/s and the actual cost of electricity was 1350W
2x Antminer S2 in BTCGUILD
1,010.99 GH/s
1,012.81 GH/s
Lower w/GH also increases the lifespan of the product.
The lifespan of the S2 increases, because they are
Upgradable
All AntMiner S2 and S2 kit will be adapted to the Hash Boards with next generation chips. Clients can freely choose the upgrade version Hash Boards to replace the ones in hands.
