I have two deltas similar to the ones you have on an S5 that runs very quite. There is a link to a video here it has 15 seconds of SP20s and 15 seconds of the S5. Not a very scientific approach but a quick and dirty comparison: https://bitcointalk.org/index.php?topic=902305.1240. I like both unit types as they both serve me well. I knew a guy that worked for Intel. They would actually have the latest processor chips sitting on shelves, never to used yet because they wanted to milk more out of their current technology. So when you see Intel processors saturate the market that usually means some new chips are coming out on the market. The public has no clue about this, and just like bitcoin manufacturer's, they with-hold information from us on purpose for financial gain. Why do you think all the manufacturers were pushing the hell out of their inventory, having big sales and trying to sell as much as they could right before bitcoin dropped below the $400's. Usually when you have and use inside information for financial gain it is illegal, but since this bitcoin market is unrelated, apparently anything goes.

Please keep the cap closed!!!!! if you are worried about the pressure, may be wait until 30's then close the cap nice and tight!! Well, like I posted before two of my pumps were making noise and one finally died today.
Were you closing the cap tightly? Did you fill coolant to the top? Can't close the cap tightly because the the heat would create too much pressure in the loop. I keep it loose so there is a vent. And I don't fill all the way to the top, but fairly close. Doesn't everyone keep the fill hole loose? You don't want too much pressure in the loop. Going from 28 to 40 is going to create a lot of hear and pressure. Agreed on this. But realistically there isn't that much pressure build up as the difference in density between 25 and 40C is 0.5% by volume. You've got ductile tubing which isn't rigid and is more than comfortable absorbing that. Not sure they are all the same. My father has 3 C1's running in his basement and on one of his pumps he went to unscrew the fill cap to fill it up a little more and the fill cap went shooting across the room and the coolant started shooting out of the top of the fill hole. There was a huge amount of pressure in that loop and his top temperature was only 41. He had some serious pressure in his loop. The only thing that could of done that to him was the heat. If there's no vent, it gets stuck in the loop and possibly takes advantage of the weakest areas where it can all leak out. No?

Going from 28 to 40 is going to create a lot of hear and pressure. Well, yes, I do keep the cap closed and use a screw driver to close it. I just meant I don't make it real tight. It is a sealed system, so I know it has to be closed. It always did make me wonder where the pressure goes to when the coolant heats up? I guess the loop is rated for some pressure, right? By the way, what would happen if you don't fully close the fill hole? I've always kept mine closed up, just not very tight. The fill hole screw gasket (O-ring) is definitely making a good seal.

I'll let you all know how it takes to receive a new one. The pumps are rated for 50,000 hours. That's 2 years running 24/7. Having ANY of them go bad in the first few months should not happen when they are rated for 50,000 hours.

I logged into my SP10 tonight and on the settings page it indicates "over-clocking (socket voltage: 217)". Does anyone know why that's there? I never made any changes to it. I just clicked on turbo fans and that was it. I never made any modifications or anything.
Here are my voltage numbers if this means anything.
Fan Speed 80 Start volts top .664 Start volts bottom .664 Max voltage .75 Max power consumption 1260 DC2DC limit 62
you should underclock that miner, my SP10's all run at no more than 840w each and avg ~1.2TH/s each. far more profitable. They cannot be ran at home...they are co-located which adds a cost. The noise/heat alone they produce is profound and wouldn't even consider running them in my home. Even the SP20, still to loud for my tastes. I like my peace and quiet when I come home from work. Considering bitcoin is $178 right now I'm just going to unplug them. They are costing more to run now. What really sucks is I shelled out $3000 ($2988) for each of them and they only ran for 7 months. Damn, I miss the days where you could setup 20 video cards and run them for over a year. Lots of people are probably losing money, doesn't seem like bitcoin is going to pump back up anytime soon, but just lower. What happens if it tanks to like $50? How can these large data centers keep running? Manufacture's have to have low ball prices if they want to sell anything I would imagine, unless the buyer has so much money they don't care losing some everyday. Price I cant argue it hurts miners for sure. On can't run them at home would disagree. You just need to have room for them. Most miners are not something you would want in your living room. I highlly suggest setting up area for miners if you have the room. Dude, I had my SP10 running in my garage when I first got it and I still heard it throughout the entire house. They have that high pitch whine that my ears pick up like a dog and drove me crazy. Maybe some people can handle it, but I could not.

Man, I love these things.
Running 2 SP20s off of a single EVGA 1300G2, fans at 10%, getting 1.18TH/sec from each for 1100 watts at the wall.
That's about $120, give or take %20 for electricity for each one. Are you paying for that or stealing it from your neighbor? Anyone buying miners now, how are you going to break even? Please tell me the secret!!!!!? Based all on risk and "hoping" what will happen?

I'll have 1 or 2 SP10's for sale pretty soon. They have been running rock solid since first turned on and both kept in a data center. Co-location costs are now costing more to keep them there, so I will have no choice but to unplug them. I believe at the current numbers each one brings in approx $150/month. They both are still at the data center, and I'm trying to find out what arrangements they have on shipping them back to me. Like if there is a cost. I remember you could run a rig for well over a year, but these have been running for only several months. And I can't run them at home. The piece and quiet is worth more then $150/monthly. If interested just shoot me a PM. Thanks.
If you'll sell the SP10s, you won't have more SPT equipment. It will take the fun out of your weekends. I'll suggest you'll buy some SP20 so you'll be able to continue. I would definitely buy an SP35 if I knew I would get my money back. It cost approx $350 to co-locate an SP35 and with current numbers today it will give you a return of $575/month and that will drop about $40-$50 every month. So it will hit that $350 number fairly quickly since I could never run an SP35 at home. It all boils down to the return I can get back and right now with bitcoin so low, it doesn't look good for any hardware purchasing for me anytime soon. Yes, I will for sure miss it and have to find another hobby for the weekends. Most likely the only users that will break even are the ones that get free electricity. Yea, a little jealous!

Those are water fountain / fish tank pumps which do work, but have half the pushing power and height as the C1 rated pump. They also have no reservoir, unless you have that pump sitting inside a small bucket of coolant or something? From the specs that one is rated around 1/2 of volume pushed. I would guess it's partially based on ambient temperature. If OP has very cold ambient it will cool the coolant when in the tube, not just in the radiator. Personally I would not go this route but I know a few through this thread have. You would use anything that holds water and is big enough to put it in as a reservoir. Reservoir's are not really anything special. You'd be amazed at how little flow you really need for most water cooling systems. Although Bitmain chose fairly small hose ports, the blocks are not crazy restrictive (and if they were, it would be a bad design) plus 2 meters of head is pretty good for a small pump. It takes a lot of energy to heat water significantly during the 3-4 seconds it spends in the C1 water blocks before it heads back to the radiator. Here's a screenshot of the current temps of my C1 and it's not that cold in my basement, approximately 60F (15.5C) Picture of flow obtained with the little pump I have 3 C1's sitting right next to one another, in the same room and all three have different temps. Ranging from 29-43. It all depends on the miner rig. I have 6 of them and I'm aware of which 2 run hotter than the others. Why they run hotter? Most likely a quality control issue with the thermal or some other thing. None are exactly the same.

I believe 2 of my pumps are starting to fail. They are making a kind of a rubbing sound and I don't think they are pushing the coolant through as much as they should, hence the higher temps. If I have to buy cooling parts all the time for this miner, I'll never break even. It is very unfortunate that the miners seem to be doing just fine, but all the cooling packages are failing or having troubles. It is quite frustrating! I'd love to buy all EK pumps, but spending $100 on each pump just doesn't make sense since the whole miner cost a little over $300.

With the upcoming diff spike and and the currant BTC price, prices for miners are becoming less attractive. Things are going to get interesting. I was about to pickup another C1 because of the quietness over the new S5s, but with the current conditions buying these miners is starting to become hard to rationalize. I hope BITMAIN continues to make water cooled models when & if things turn around.
With BTC now under $300 there is no sense to buy anything. I would suspect people are shutting more hardware off then buying new stuff. I'll be selling my 2 Spondoolie SP10's very soon, since I can only co-locate them and I get charged $150/month for that. An SP10 makes about $150/month so I'm just wasting energy right now. It would be perfect for the guy who can run it from his home or doesn't have to pay electricity.

Hello
Opentoe, I know one person with the same problem with one C1 bath 1.
We configure the miners with standard voltage 0725, the chips to 256Mhz save and aply. Wait 1 minute for save and apply and turn off the miner 1 minutes. Turn on and wait 10 minutes. In the hash rate is less of 900Gh, we continue turn off, wait 1 minute and turn on again until the hast rate is near or 1Th.
Please, is important wait 1 minutes between turn off and turn on.
Regards. Antuam.
Really? This is actually a batch 2 unit, but anything to try I guess. The longer it runs, the lower the hashrate. So I'm thinking a buggy firmware with a memory leak that's killing it because when I power cycle it, jumps back up to 1005TH and then slowly starts dropping, real slow. I'll try this "trick" once it gets back down to 900 again. Thanks. Which pool is it on? I don't think its the solution but worth a shot. I tried Ghash and BTCGUILD. Both steadily dropped the hashing rate to 900 on two of thrm now. Regretting a little a bought 6 of them dince only two are performing at spec. I don't have a solution for this unfortunately, although the only indication is that you have 4/6 units which degrade over time and its not a widely reported problem. Can you think of anything environmental that might be contributing? Circuits maxing out / getting warmer? I'm sure you're setup is good though. I have 6 of these running. I know how to maintain them and get them running. Since it appears to be only happening on one unit, likely a hardware issue. The last thing I need is down time on any hardware or I'll never break even in years.
