2$/G Is a little for me, i think 1.2-1.3$/G is a reasonable price for everyone
You can get under 1$/GH in my group buy, but for pre-ordering. Nobody has 1.2-1.3$/GH for in stock items.

Will give the Turbo mode a chance too.

SP10 1,497.78 GH/s
Looking good!

This is the future but I am not sure if mineral oil will be the mass deployment coolant. It is still pretty messy to service. I am working on a project with another coolant that is a little less messy. Regardless this is cool and green tech. I love it.
It should be possible to deploy immersion cooling at large scale, as shown here: https://bitcointalksearch.org/topic/visit-of-asicminers-immersion-cooling-mining-facility-346134

I STILL HAVE A UNIT IN MY LIVING ROOM, YOU GET USED TO THE NOISE LEVELS AFTER A WHILE.
I don't understand how people can sleep in the same room with their rigs??? I go sleep to other room or otherwise i couldn't sleep when hearing the noise.. That just doesn't sound a smart thing to do.
I often sleep in the same room if I'm too lazy to move, you get used to the noise pretty quick. It's also a constant noise so it's less disruptive than traffic for example.

He mentioned living room, not Bedroom

send it to me I have a place for it.
seriously I am in Howell NJ 07731.
pm me with a price and I will take it off your hands.

Could we get a video of the fan noise. Start video, turn unit own, struggle to hear you talk over noise 
That should be possible --
I now have some more numbers to present:
Code:

1.00Th / ~720W / ~quiet / 1,39 GH/s/W | 1139 Gh/s | 29 °C / 67 °C | 780- 820 W
1.35Th / ~1100W / ~quiet / 1,23 GH/s/W | 1341 Gh/s | 29 °C / 82 °C | 1150-1200 W
1.43Th / ~1350W / normal / 1,06 GH/s/W | 1412 Gh/s | 29 °C / 79 °C | 1340-1380 W
1.47Th / ~1370W / turbo fans / 1,07 GH/s/W | 1456 Gh/s | 29 °C / 76 °C | 1380 W

------------------------------------------------+-------------+---------------+---------------
The power measurements were done on a 230 V circuit. The numbers for every mode except "turbo" and "idle" fluctuated, so I included the lowest and highest reading. The "average" power draw is somewhere in between. In normal mode, the unit hits the advertised 1.4 TH/s exactly. "Turbo" mode does not give much more performance (about 3,1%), but decreases the temperature by 3°C. The lowest performance mode also gives the lowest temperature, whereas the other quiet mode gives the highest temperature (3°C more than "normal") and a 5% reduction in performance compared to the standard mode.
So, as the "quiet" mode does not deserve its name (I would rather call the mode "efficient", as that is what is is - more energy-efficient than standard/turbo) - my recommendation is to either run this unit using the (slowest) 1Th-setting, which will give the best performance per Watt and also a low temperature. Otherwise, one should choose "turbo" mode over "normal" mode because you get both a lower temperature and a bit better performance at only marginal increased power consumption.
Thank you for the review too. I was using the Normal mode until now. Will give the Turbo mode a chance too.

Hey guys, it would be nice if you could keep this all time favourite discussion "mining vs. buying BTC" out of this thread
I would like to have this thread dedicated to my SP10 review and questions regarding this unit/review.
(I'm not saying either option is better. Everyone has to do due diligence. Then, buy mining gear or buy BTC or buy nothing.)

This is not going to reduce the loudness by a single dB, sadly.
