Hi Guys, I have been given permission to host 1x SP35 miner in my test enviroment at work which currently contains 5 other servers all pumping out heat into the comms rack in my office, unfortunatly it is not in a temparature controlled enviroment (yet). This should be fixed in the upcoming months where the rack will be moved to an air conditioned room they should also be upgrading me to a 30amp supply to my rack. Currently the intake temprature on my servers are reading 38c and they will shutdown automatically if intake temp reaches 42c. https://i.imgur.com/NBE7YvP.jpgIf I add an SP35 in this rack do you think it will push up the ambent temp up those magic 4 degrees and cause problems for my other servers, if it will how noisy are these units as I could leave the back door of the cab open in order to release some of the heat if required. If things go well I will ask the boss if I can add a 2nd one in order to bring my # rate up to 10th/s

you are gonna be pushing it... that SP35 is indeed gonna put up that ambient by quite a bit and without air-con, you are gonna have issues.
best luck with it.

And with air conditioning included, you basically will have to double your power usage (it will emit 99% of the energy as heat, you will need equal amount of energy to cool that heat) so that device will never make enough money to cover its own cost. you are gonna be pushing it... that SP35 is indeed gonna put up that ambient by quite a bit and without air-con, you are gonna have issues.

3650W is 12,447 BTU of heat. You will probably go over without cooling.

Agreed temps will easily rise 4 degrees. You might be able to underclock the SP35 quite a bit and make it work, but really doubtful.

Thanks guys,
That is the answer I was expecting but not the one I wanted, it does make sense given that the S5 kicks out enough heat that my lounge is a toasty 21c without heating. I was hoping that if I left the back door on the cab open it would keep the temps low enough that I could run it on a temporary basis until the rack is moved to its new location in a temperature controlled server room generally kept at 18 - 21c @ 30% - 36% RH
@Jamphone I am interested if you could elaborate your response regarding it not paying for itself.
My work is allowing me to host this unit FOC in my test environment where all costs are covered (Power & Data) so my only cost is roughly £1600 for the hardware itself. Given that my current setup (roughly 1.3th\s is yielding me 0.1 BTC per week) adding a SP35 should yield me roughly 0.5BTC per week. I have to give my manager 2BTC for hosting (up front fee not a re occurring cost).
So providing that it keeps making BTCs for me i will return a profit eventually; especially if the BTC price jumps in price to some silly price again then all will be well.
The only way I can see myself not making money off this is if it needs to be hosted in our T3 Datacenter which comes with a £450PCM fee + Electricity, or if the BTC price tanks and never recovers.
NOTE: I am not rubbishing your response all input is very valuable to me but I am struggling to get past all of the people who say " you will never profit/break even mining is a waste of electricity. the difficulty is too hard" I would like a balanced argument on both sides.
Thank you again for your input.

Isn't AC roughly 1/3 the energy again to remove the energy, not 100%? And to the OP, if you limit the SP35 to 800W per PSU it is crazily quieter as the PSU's fans remain low @ 40C. Or 950W @ 36C, 1100W at 30C, 1200W at 26C. Your numbers might vary slightly as my temp readings may not be entirely accurate.

I am also confused by this argument. I see a profit can be made if you stay efficient with your set up. I think that is because I don't see the word "Millionaire" when I read the word profit. ALOT of people on here say mining is dead and gone, BUT they still do it!!! They're on here everyday posting/reading topics and posting pics of their gear,...so if it's not profitable, even a little WHY ARE THEY STILL HERE???I think you're in a good position to make a Profit---Go For It!!!

Funny how people always change their tune. The same people who said in the summer of 2013 that BTC mining was dead and no point in doing it were then the same people buying antminers s1 up the ass in December because BTC price when over $1000. Now with prices low again the same people now saying again that mining is a waste of time. Yes mining now is very difficult. Given the low BTC price and difficulty you are not going to make a profit or cover your cost. Unless you own a dam and are making your own electricity, you will not cover your electric cost for running the miner or air conditioning. Some people can mine at a loss with the hope of future profit. This is a good time now for the hobby miner, not so much for the big mining farms.

To the OP, do you have any other options, say a backup plan if things didn't work out? Could you run the unit anywhere else temporarily if needed?? Or, downclock them both? I am always looking for a silver lining, and with the prices of things at this time we must look at things as an investment, or fun worth the price, but I also want to make a profit. Actually, I am happy breaking even at current pricing because the knowledge gained is hard to put a price on. I was mentioning to someone just moments ago that I was considering speaking with the main owner at our place. We have worked closely together for many years. I think the only issue would be that if I do it others will want to, and then the whining starts. It has happened before over company vehicles heh. But, you never know until you ask. Another thought for a backup plan is if you decide to go ahead and things didn't work out you could have a buyer already lined up. Depending on how you made the deal you would not be out much and it is not going to take long to know if you have issues, even downclocked, what would it take, one hot day? Where I am we still have a couple of winter months I am enjoying. I hope you are as well. I will check back on this thread and I say if you think it will work, if the line is that close in your mind, you ran the numbers, then get yourself a good backup plan and go for it. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Transaction fees go to the pools and the pools decide to pay them to the miners. Anything else, including off-chain solutions are stealing and not the way Bitcoin was intended to function. Make the block size set by the pool. Pool = miners and they get the choice.

At 500 watts each that is 2.5 Kw of electricity. The SP35 at full speed will be doing 3.6 Kw. So they are going to be seeing more than a 100 percent increase in the electrical cost associated with this rack of equipment. I don't think they would be willing to cover a 600 dollar electric bill per month FOC if they knew. I want to see how they feel after a few months of big electric bills.

AC power isnt 1:1 with the kw of heat, its generally 30-35% depending on efficiency of the AC and other factors and i can attest to the second point. I just setup an SP30 (basically an SP35 / smaller PSUs) to run at 30-40% fans in the daytime (3.6TH/2kw) and ramp up to 80-90% (4.2TH/2.6kW) at nighttime when noone is around and power is cheaper. at 40% fans are comparable to an Sp20 at ~30%

The op posted that the company is relocating the existing equipment AND the SP35 to a better controlled environment that is going to have upgraded power. It sounds as if the op has talked this over with the people "in charge".

You presume a lot with this post, it's entirely possible that could happen but I sure hope the basic questions like how much power would be used were asked by the authority approving permission.. We allow things like that to run knowing exactly what it will cost, the treatment of facility costs vary depending on the business but in our case it is a fringe benefit for employees and we know exactly what we are doing.. Another local facility provides 220V 30A as a benefit for the same purposes, in short while you make a valid point it's entirely possible it's no issue for them...

Everyone is assuming a lot. He might work for a Fortune 500 company. He just maybe located in a small office with a small server room. In which case I doubt they would notice an SP35 on their 200 sites of electric bills. He might work in a small office that has power included in their lease so building is paying the bill. He could have his own company wind farm powering the office. I say if he has permission let him do it, if he has to unplug it I will buy it cheap ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) LOL

Could his work be ok with the increased cost of hosting a SP35? Sure. He could be trading his services for the hosting of his equipment. In this case it could be a good exchange for both parties. If everyone is aware of what is going on and ok with it then I say more power to him and why not buy a second SP35 and have them foot the electric bill. If they really don't know and he values his job then better make sure they are aware so he doesn't get fired. All I am saying.
