how noisy is the SP10?
Reason for selling:
We live in a very old home and the noise level is much higher than anticipated.
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.

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.
+1 its a vanity design.
Which isn't a bad thing.
Its more like "look what we can do, bet you can't do this" sort of thing The techie in me loves it, but the miner in me finds it a bit strange.
But its true that putting it in a 1.25U form factor has no real practical purpose because you need a *very* specially designed datacenter that will allow that sort of power and thermal load in a 47U rack space.
to be honest, its not even just the thermal density - its the damn fans. (presumably the psu fan is loudest, as is common for server power supplies to sound like nails on a chalkboard in a rainstorm). A 3TH/3U version would allow 120mm fans that can pump lots of air without the high pitch.

Oh I agree from a "have my miner at home" POV which I am very much in the target market of, the noise issue is the biggie.
Spondoolies, what happened to the work with the PSU supplier? I thought that the cause of most of the noise according to past reports from you and Doogie's reviews showed that the major source of noise was the PSU fan and that you were trying to get it turned down because it didn't need to be running at that speed 100% of the time.

You should definately go for maximum ventilation.
Aim for atleast 150cfm per sp10, ideally blowing onto the intake side.
Then extract air at the same cfm at the outgoing side. As far as i know, growshops offer cheap extractors with massive cfm.
Keep in mind that when you go for "free" air cooling, cfm is all that matters as ΔT*airflow = cooling capacity.
While a solution with portable AC is typically easier to build, the free air cooling solution uses around 30% less electricity.

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.
[/quote]
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.

Just a word to the wise, if you want to duplicate my 5U rack exactly, be prepared for a lot of work trying to determine what screw to use where. I used almost none of the screws that the kit came with, instead substituting various nuts and bolts instead. Some, especially the left server ear, was a close call involving some filing and some swearing. It does give you a basic set of metal parts that can be assembled into a server rack, but it is not an easy path.

Thanks guys, my one SP10 I'm running...
Temp Front/Back 28°C/76°C
Room Temp about 26°C
Mining Rate: 1.45Ths @ Turbo Speed (~246v)

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.

Tip for warm rooms: It seems that the SP10 runs better and more stable at Normal speed than at Turbo. Try it!
Can you be more specific reference "runs better", meaning your getting a higher hash rate?
Thank you,

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

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.
Nice, thank you.
