Quite curious from the fan experts, so those six small fans on the one side running at 100% are  extracting the hot air satisfactorily. What if you got a second set of the exact same six small fans attached them to the intake side, even if on the outside, to push air in and through to the other side, then reduced each set to run at 50% speed. Would that equal just the one set running at 100%?

how noisy is the SP10?

Reason for selling:
We live in a very old home and the noise level is much higher than anticipated.

I think the main design mistake Spondoolies-Tech made with the SP10 was cramming it into a 1.25U case, which forced them to use very small and very loud fans. Most people don't need the SP10 to be 1.25U. Even in a datacenter, a 2U or 3U design would have been fine in 99% of cases. Most data center racks are between 40 and 48U, and there is a limit on how much power can be supplied to a rack. I doubt many data centers can power and cool a rack that contains 20 SP10s and draws ~25KW of power.

Otherwise, it looks like a very well engineered product.

It's not a design mistake, its a very well engineered (master) piece of hardware and so is the cooling system, its just not engineered for a home environment. If your looking for something to have at home then expect to mod it (at your design and expense), or put it in a data center, or buy something else that outputs less hash rate. To me the noise is music/money to my ears.

Respectfully,

~Blaise

My point was that the design doesn't even make that much sense in a data center environment. Why use a 1.25U case when a 2U or 3U case will work just as well in a data center, and larger fans can be used that aren't as loud as a jet engine?

Very few data centers can support tightly packed density of 1.25U units that use 1250W each.

Any pictures available, maybe?

Sure:

Would you provide a link for the supplier of your 5u rack I might be interested? Also should you feed your your SP10's ~220V instead of ~110V you should even get a better hash rate.

Best regards,

~Blaise

I made the rack using 5U rails from Ebay: http://www.ebay.com/itm/221434430401, added 1U shelves from Amazon: http://www.amazon.com/gp/product/B0060RUVBA, then used Cisco server ears: http://www.ebay.com/itm/400665564949.  Lots of trying different size screws, nuts and bolts was required, but the end result was great.  A more complete rack kit would have made it a lot easier.

It's not obvious from the picture, but the three SP10s are connected to 240V NEMA-6 outlets above the shelf.  The 120V wiring that is visible is for the network switches and other mining gear out of the picture.  The SP10s are still steady at 1.42, 1.43 and 1.44.

Just curious what kind of extension cord I need in US to operate this unit at 220V, is it NEMA L6-20 Locking at one end and IEC-60320 C13 at the other end.

I used these: http://www.amazon.com/gp/product/B00EJVZLNC.  So NEMA 6-15 on the plug end, IEC-60320 C13 on the server end.  I installed NEMA 6-20 outlets, which are carried at local hardware stores here because they are common for air conditioners.

Tip for warm rooms: It seems that the SP10 runs better and more stable at Normal speed than at Turbo. Try it!

Is there any type of cabinet we could buy to reduce the noise on them ?? Also is it possible to had ventilation on the cabinet?

Really appreciate this help, because seems the SP-10 is very loud and i´m afraid i won´t have place for it

Can you be more specific reference "runs better", meaning your getting a higher hash rate?

Thank you,

Getting 1.45Th/s at Normal speed. With turbo I was reaching 1.50Th/s or 1.52Th/s, but from time to time it slows down at 1.40Th/s. I guess it's from the heat. I really need that 5U rack.

Running 3 SP10s at 240V, PS limit set to 1260.  Fully overclocked, I get 1.42, 1.43 and 1.44 in a warm room (26C).  At normal/medium speed, I see about a 1% drop to 1.41, 1.41, 1.42.  Working on improving ventilation in room to see if I that helps at all.

My three front/back/hashrate:
27 °C / 72 °C / 1439 GH/s
27 °C / 74 °C / 1443 GH/s
28 °C / 73 °C / 1451 GH/s

That's in order from the picture from top to bottom.  Room temperature is currently 24 °C a few feet away from the miners.
