I replaced the fan with below and added a 2nd (push / pull) in the rear. Cools fine and a lot quieter than stock fan configuration. Fan comes with extra long connector for 3 or 4 prong. Plugs right up and reads and controls as 2nd. fan.

cool. I thought that silverstone 140 mmm does not fit and needs to be cut. Did it fit well without any cutting of shroud both in front and back? I thought the S5 uses 120mm fans?

This is real simple, you don't even need a calculator for it. From what I've seen, an S5 will draw about 650W at the wall at 375M (estimated on the high side). So 0.65KW x 24h = 15.60 KWh Can someone do me some simple math today please?
I need to know approximate how many kwh per day that an S5 will consume based on a frequency of 375. Assume a constant ambient temp and I get about 1.2 TH. Please let me know how you did this calculation.
This just has to be rough and dirty. I'm exploring designing a small hobby farm.
Thank you.
That's exactly correct. The general form is: power consumption (in KW) * time (in hours) = kwh Thanks guys. Most helpful. My numbers say I break even at 5 units and I am estimating expenses on the high side. Basing everything on btc at current price. I may play with my numbers knocking price back to 1btc = $200. BTW Bitmain, I need units to buy

Anyone put a S5 in an S3 case (with the top) and then see how well a push/pull dual fan setup works?
Not to bump an old thread, but in my experience many miners are giving far to much though to push pull, water cooling, etc - for their S5 units. The method outlined in my Guide on Vertical Positioning of your units with a simple box fan keeps 6 S5 Units within close proximity to one another, with a single fan each - all very cool, and overclocked at 392.50. There are detailed diagrams in the thread found here: https://bitcointalk.org/index.php?topic=945775.0Strato But that loud 70dB is still there using the stock fans. If you have 6 of them in close range of one another you will need ear plugs.

Sorry for bringing this up, but installing a heatsink on that sensor wouldn't that give false temp readings? Don't you want the real temp reading, or trying to keep the temp sensor cooler is a good thing? Yes it would give false temp readings. They wanted to falsify lower temp readings in order to trick the fan into spinning slower (quieter). There is no benefit to the sensor itself. I had gotten an S3 to have its fans run faster by not putting thermal compound under the temperature sensor. Recently I ran 12v to the blue wire of its exhaust fan and it runs hard albeit loud. I now figure it was a mistake to skimp on the thermal compound under the temperature sensor. Heatsink draws less heat from that spot from the board making it seem hotter than it would be thus the fan runs faster but nearby ASICs get hotter. Must get in and correct that one of these days. Am looking forward to putting a single pole double throw switch on a C1 fan so it will be taking power for the fan from the hashing board until I need better cooling in the summer when I'll flip the switch and give it 12v and run it full speed. I've order a pulse width motor controller for a few bucks and am going to put it between the 12v and the blue wire. If you want the fan to run slower that would work. Thing is if the designer feels he needs that airflow then ....

Is that a controller designed for 3-wire or 4-wire fans? Also, on 4-wire fans the blue wire is internally tied high and the PWM signal is actually done by pulling it low during the off time, so disconnecting the blue wire is probably better than giving it 12V directly. If the 12V you're feeding into the blue wire isn't current-limited, you could be roasting the board's fan controller.
A 3-wire fan controller may not work for a 4-wire fan driving the blue wire, because the 3-wire probably provides power on the high and a no-connect on the low instead of a no-connect on the high and a GND on the low.

For this past week my S5 has been running well. This morning it is unresponsive. Apart from using Teamviewer or M Miner or sshing into the miner. Is there any other method one can use to reboot the miner? The miner is on a remote site and i remote into a raspberry pi that i use to web into each miner.

http://eddiesilva.me/wp-content/uploads/2015/03/antpool.jpgI've been trying to find an explanation as to how to read the cgminer screen that I posted and what values I'm supposed to be shooting for. This setting is the most stable (HW at .0003%), which is good, I think and not over .02 which is bad? Utility is miner efficiency? According to various articles i foung on google (they were all GPU based machines) utility needs to be high. On slush's pool its 20, antPool is what you see. I guess what I'm really asking about is if my screen looks good and where do i need to make improvements?

use ssh / putty login with username root password admin if you want to reboot the miner, use reboot command just type : if you want to restart te cgminer, use /etc/init.d/cgminer.sh just type : /etc/init.d/cgminer.sh restart

I cut the wire. I could see how splicing 12v to it while leaving it powered from the hashboard would threaten the hashboard. I don't take the 12v from the 4 wire harness. I take the 12v from the power supply. A three wire PWM controller, drive wire to the blue wire, common ground, should work. I'll let you know. Tho slowing down the fan likely means excessive heat at the hashing board if hashing isn't throttled. I see the C1 throttles for overheating - a connector to the pump came loose and was found when I went to investigate 900GHS hashing where I was expecting 1THS. Didn't know that about a three wire but the controller I bought is a 4 wire.

If I order 4 C1 now, in how many days I will get the device in Italy?
Do you think it is possible to get a roi with these devices?

Thank you.
.52 x 1200 gh = 624 watts x 24 =14976 watts divide by 1000 = 14.976 kwatts or 15 kwatts rounded + or - .5 kwatts if you have bronze or plat psu. the .52 per gh I used is for a gold psu

What's the best Delta replacement fan to get that is quieter than stock? I can't believe how many Delta fans are out there. Literally hundreds of different models. Crazy.

Approximately 4 working days as long as it goes through customs well.

The only 2 critical values are the hash rate shown on your S5's page and the hash rate reported by your pool (as an average). Everything else is surplus to what you need to monitor in regards to your income.

I am wondering why your fan speed is so low? I have modded my fan setup, Noctua NF-F12 2,000 pwm push and an arctic 1500 pwm for pull. room ambient temps are about 24c during the day and 19c during the night

I don't think the price is too bad. Although it has room to go down, I recently bought 2 S3's and a PSU for about the same price that I would have got and S5.

Everything else is surplus to what you need to monitor in regards to your income. Ok, great!!! so my s5 never shows that i am dipping below 1Th/s but in the pool, for 30m it shows 977.5 Gh/s. everything else according to the pool seems to match up. here is my pool http://eddiesilva.me/wp-content/uploads/2015/03/poolhash.pngand here is my current hash http://eddiesilva.me/wp-content/uploads/2015/03/updateantminer.pngSo why the difference? sometimes the 5s hash does drop and sometimes it does rise, I think it has to do with the psu but I'm not sure. The average stays about the same so I know the miner is working at about 1.1Th/s which is where I want it with my current setup. I could always do more hashing but it doesn't seem as stable when it is not at this setting. As an average as you stated dogie, I should be watching the daily hash on my pool and miner settings and now worry about the 5s and 30m, 10m on the pool? I seem to be getting consistent payout, i guess that is all that matters.
