Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
batch 6 shipped last night - supposed to arrive friday but my batch 5 are still stuck in customs 
My batch 5 was stuck in customs as well because Bitmain overstated the value at over $7000 per miner. I just had to call FedEx and email them a screen shot of my order and state that the value was overstated due to human error. They'll also want to know what the miner does. This explanation got it released right away,"This particular item is a collection of computer processors called ASICs that perform a specific computational task. Alone, this component does nothing. Once I assemble other pieces and attach the ASICs it solves complex computer math problems. In the most simplest of terms, it is just a computer component."
Hope this helps.

I hate S7. Killed all my profit on hashnest. 
With the hash rate dropping and block generation time going up, it's killing everyone's profits. Give it a few days for everyone to receive their S7 and the hash rate will shoot back up and all the pools luck will start going back up. Bitmain is definitely controlling the hash rate and difficulty these past few rounds of difficulty increases.
Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
Funny how the hash rate is dropping as soon as the orders start shipping. I'll bet the fans show up nice and dusty but Bitmain will say they are brand new units.

Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH
I have 2 B4 S5's. Been running both at 375mhz each on a CX750 for 27days. One has 267 hw errors and the other 6547. Both avg 1235 gh/s.
Anyone tried 400mhz on a CX750?
Anyone tried 400mhz on a CX750?
Yes, all mine are on CX750's, total of 8 S5s running 400mhz, lowest is 1210 gh/s highest is 1300 gh/s. Does seem to make a small difference on most but a couple of my miners throw way less errors at 375 and still mine in the 1200 gh/s range, just play with the settings on each to see what works best for each miner.
Re: ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.25/GH & 0.51W/GH
would like to report strange behavior.
i have a set up with cold air being taken from outside and vented back out.
seems the miners cant handle being TOO COLD??
i had several s3 and s5 stop working because they were TOO COLD!
the s5 one board reports 0 degrees and does not hash. restarting it or warming it up fixes the no hashing. the s3's report a temp of 251 degrees and stop hashing all together until removed from the enclosure and warmed back up.
please advise.
thank you.

Don't vent back outside or don't vent all of them back outside and you should be fine. My ambient intake temps are -5 C but I vent into my basement for extra heat and since all the heat doesn't make it to the basement it keeps the miner room just warm enough to keep them running at a stable temp.

I guess I'm an idiot then since I didn't go out and waste money on a second fan, remove the shroud so junk can get sucked into the miner and potentially snap a fan blade (trust me they're fragile, received one broken during shipping). Been running lanfeusst's modified fan control file for about 24 hours now on one of my miners, RPM's still holding steady at 3360 and temps in the mid 50s and happy to report no spontaneous combustion has occurred. Oh and I've been and Engineer for 20+ years and have somehow survived more than 2 days at every job. Keep up the good work lanfeusst.

S5 firmware fan speed mods .....
I stumbled accross this topic https://bitcointalk.org/index.php?topic=940250 where they had a mod for the S4, and thought about making a firmware mod for the S5, in the process, the person who made the original mod to the module controlling the S4 fan has come up with a mod for the S5. Here's the link to the message: https://bitcointalk.org/index.php?topic=940250.msg10327889#msg10327889
I have not tested the firmware as I received my S5 with the stock fan DOA (got in touch with bitmain and they want me to take videos of it and / or buy something from them before ... blah blah ... for another day that one!). If anyone is willing to give the modded firmware, please give it a go and provide feedback. there are links on the messaage, but I'll reproduce them below too:
1. fan_6 - slower than stock - https://mega.co.nz/#!MVtHXBKC!VEymK0FxLpuXTl5ZpxnNxlQNKOsp15V0vRy18Vb7dPI
2. fan_3 - slower than fan_6 - https://mega.co.nz/#!JFNnQALR!3x501jLm1GyzUlDMZ4USWGmDHYCyZKSSiNp4UWRWUnM
3. stock firmware (also on bitmain site) - https://mega.co.nz/#!1ENCRYIb!pbSf4wXt4nwX_0IYTH1LRh0mZ9_Gw3KgbCel8zyhOjo
If you try the firmware, please provide feedback either here or on the thread linked above to lanfeusst. This mod can also be the pilot for a permanent mod for updating cgminer et al!

Since nothing survives a reboot on a S5, you'll have to do this a little different than the S4 to test without repacking the firmware.
To use it :
Change 192.168.0.16 with the Ip address of your miner
scp bitmain_spi_fan_6.ko root@192.168.0.16:/lib/modules/3.8.13/kernel/drivers/bitmain/ #Copy the file to the miner
then ssh to the miner :
ssh root@192.168.0.16
then :
cp /lib/modules/3.8.13/kernel/drivers/bitmain/bitmain_spi.ko /config/bitmain_spi_original.ko #Makes a backup
cp /lib/modules/3.8.13/kernel/drivers/bitmain/bitmain_spi_fan_6.ko /lib/modules/3.8.13/kernel/drivers/bitmain/bitmain_spi.ko # Copy the new file to the good place
cd /etc/init.d/ #Change directories
./cgminer.sh restart # Restart cgminer
I've tested both files:
Ambient temps here today are -5 C & I'm running 9 miners in this rack.
bitmain_spi_s5_fan_6.ko runs the fans at 3240 RPM and temps are averaging 56 C
bitmain_spi_s5_fan_3.ko runs the fans at 2760 RPM and temps are averaging 66 C
So I think I found a solution to the high pitch whine of the stock fans. We all know the guide vanes are what's causing the pitch. I received a fan with a broken blade on my my batch 1 S5's and Bitmain was kind enough to ship me a new one. I decided to do a little experiment today to see if reducing the number of vanes would change the pitch, which for my ears (healthy 35 year old) now sounds more like a S3.
You notice on the vane there is a thicker part on the outer edge, I took some wire cutters and cut every other vane right where the thin part of the vane meets the thicker part (careful to line up the fan blades so you don't accidentally cut one). I then used my thumb and as close to center as possible I just pushed down on the cut vane and it popped right off. Note that the power wires run down one vane so you probably will want to start there and you'll still end up with an odd number of cuts. Here's a picture and for those brave enough to try it, let us know your results. My temps are exactly the same and I do use a high cfm pull fans as well. Still experimenting with those, so far the Silverstone Tek 140mm x 38mm Fan seems to be giving me the lowest temps but these S5's seem to run in all different temperature ranges so it's all subjective.

That has been my thought/plan if and when (a big if and when) I get S5s except I would be leaving only 3 or 4 vanes and Dremel the rest of them out "clean". If that will not be satisfactory, there's always the Delta fan option. I'm glad to know that it did make a difference.
My only suggestion would be to remove and test. The vanes do make a big difference in channeling the air down the center and across the heat sinks. I have higher CFM and higher pressure fans that should in theory cool the S5 down better but without those vanes to center the air they aren't as efficient and my temps get dangerously high. Unfortunately we're stuck with the stock fans or Delta's, for us home miners that don't have climate control.
But you already said, "My temps are exactly the same" (after cutting off some of the vanes). You now seem to say that (cutting off the vanes) affects the temp. Did it affect your temp or not? Which one is it?
The number of vanes I removed did not change the centering of the air flow affect the vanes create and my temps did not change. Cutting them out to only leave 4 I think would change that centering effect a possibly temps, I'm just saying if you're going to remove more than every other one, you might want to do it carefully and test between each cut.

Re: ANTMINER S5: 1155GH(+OverClock Potential), Jan 12th Shipping $0.28/GH & 0.51W/GH
Stock fan produces ~69db, which is not typically tolerable in the house (apart from basement, attic, garage, shed)
Fan play to have as much hash as possible while maintaing low dB:
~30C ambient
1. Noctua 3000 PWM ($24.5, 110CFM, up to 3000rpm, just 41dB) in push position: ~59-61C at 325mhz, 1070Gh; less stable at 350mhz.
2. Scythe Ultra KAZE ($15.3, 130CFM, 3000rpm, 46dB) in push position via molex adapter-worse than Noctua, temp rising close to 65C at 325mhz, discontinued. Strange result as this fan has nominally higher CFM than Noctua.
3. Noctua in push, Scythe in pull (connected to molex through included adapter), up to 337.5 mhz is stable (1100 Gh).
Conclusion: adding Scythe ($15) in pull might be not worth it as it adds just ~30gh.
I simply taped Scythe to exhaust in pull orientation because could not find proper screws yet.
Question: anybody knows what are the characteristics/dimensions of the machine screws Bitmain is using for fans? They seem to be in between 3 and 4mmX42mm, but I wasn't able to find such screws easily. They are not 3X40mm for sure. Anybody have a link?

Hi, the screw we're using for fans is PM4*42.
Thanks, but it is a little cryptic. What is PM? The search for "PM4*42" or "PM4*42 screws" returns nothing relevant.
can you point to the source that is readily available in the United States? Amazon, ebay, grainger, english version of alibaba (less optimal because of long delivery time), etc.
In the US they are M4-.70 x 40 without the fan grille and M4-.70 x 45 with the fan grille. Mine are Hillman brand, got them at Lowe's.
Re: ANTMINER S5: 1155GH(+OverClock Potential), Jan 12th Shipping $0.28/GH & 0.51W/GH
I ordered 30 of these... but they have 4 black wires. The connector has no markings... I have no data sheet. I have no clue which goes to the S5 Red White Black Blue.
Data sheet for the fan can be found here. Look on page 5 for wiring info:
Pin 1: Positive [12V]
Pin 2: PWM control IN
Pin 3: RPM reporting OUT
Pin 4: Negative
That's going to need rewiring to fit on S5s as normal 4 pin fan headers are:
Pin 1: Negative
Pin 2: Positive [12V]
Pin 3: RPM reporting OUT
Pin 4: PWM control IN
Might be worth sending back.
Dogie, I think you have pin 2 & 3 reversed there on the top.

You need to convert to 4Pin with PWM small Molex from the pinout on this diagram:

I'm surprised that the discussion about replacement fans are more focused on their airflow volume (CFM) rather than static pressure (mm/H2O) which is more significant in heat sink/radiator applications. High static pressure fans are more capable of penetrating through dense heat sink fins such as in the AntMiner devices. I think there's a reason why Bitmain engineers equip their units with very powerful industrial 12038s with high static pressure (directly proportional to loudness) instead of just mainstream consumer-oriented 12025s.
true in the case of one push fan only. but two high cfm fans as push pull get around that.
since neither one needs full penetration of the heat sink using high static pressure, but if you don't care about sound the stock fan with a good pull fan cools best.
Push-pull configuration is only effective in an enclosed unit (S3) and not in an open-chassis design (S5) though.
While that should absolutely be true, I can say in my experience the front heatsinks went from too hot to touch to cool to the touch with a high cfm pull fan installed on my S5's.
