Amended:
Quackers, did some reading ... AFTER posting questions
but still some input would be nice.
What is the CFM capacity of the stock fans?
found this one, I think... 238.09
but then it further states 27.6W Power consumption, 4300 RPM, and 60 DB-A
(my S4 at stock is running at 3600 RPM and the rear howlers are 74 DB-A so my Android tells me)
I don't want to imagine 4300 ... there has to be some relief, no?
Any recommendations of replacement fans?
Considering Delta 1212SHE-F00 ... guess only as possible front replacement... (know this one, works on S5 very nice, 51 DB-A)
Read through Digi-key catalog for Delta Fans... This seems to come closest to the stock one...
Delta Electronics AFB1212GHE-CF00 (scary 5200 rpm), but wait, there is more ;-)
this one at 1ST PC CORP. Delta QFR1212GHE-PWM (6000 rpm, 210 CFM and wait for it ... 64 DB-A at a 'cough' 39 bucks).
Does anybody know any of these fans? PWM working of the QFR?
(AFB 4 pin Molex power and RPM sensor TAC output through its 3 Pin) I need to modify something here? (I really suck at modding)
thank you

All companies have some issue, I am a HUGE Bitmain fan though, I have over 80 S3 a couple S2 and now 16 S4s running. Never an issue with the S3's, couple small things with S2, but the S4's I am hoping is just the SD card reseat - they emailed me to try that out.
Other Bitcoin tech companies have a much more checkered past, with pre-sales, and over pricing to the extent you can't ROI on the gear. Keep going Bitmain, and I'll keep buying.

Bitmain is guilty of pre-sales and some would argue their gear is overpriced.
Like the $425,000 "sale" for 1 PH/s of hosted power, plus electricity.

Hi,
I will share my experience with my order, sorry if you are tired of reading same things.....but I need to share my feelings, hope that someone will be able to help me one way or other.
I bought 32 units on black friday, only after one week mining, 6 PSU gone, and one PSU fan.
I had to wait 20+ days to get the replacement PSU, didn`t send the fan ( I replaced myself and is not the fan so they should send another PSU).....and no compensation for all inconvenients coming from almost waisted miners they sent to us.
I said during that RMA that I was afraid cause 7 PSU broken on first week is almost 21,8% of mining power off, a whole month.
As is obvious we had to pay shipping costs and clearance for the PSU, again.
In the last week, 12 PSU gone away, one per day.....only some days before Bitmain warranty expires......
So, from 32 miners: 19 PSU failed....around ~30% of the order in the first trhree months.....wow.
Sadly four miners have got issues with:
• Faulty chips, I made my own troubleshooting changing cables to isolate the problem, but Bitmain did not send anything......
• Ethernet connection.
• Fans in no working conditions.
• Some of the cables, arrived broken, burnt, and full of dust and other rubbish. What kind of new is that? I have a video of that.
• One ChipBoard has its Screwed 12V+ and GND- connectors lost, cause the first time we had to screw off the cables they just got broken, just like if I had used a Katana and we were cartoon.
• One miner only hashes if the initial Bitmain pool data is on the configuration, cause when we change it, the miner gets lazy, no hashing.
I really enjoyed this order, my first order to Bitmain.....till now they did not solve any of my issues quickly....Mining Asic manufacturers.....I was dreaming that someone could make the difference, not only on the technology, they should take care of their Customer department and the relationships they handle. Customer is the same as Future, why to renounce such way.
Best Regards.

yup I got the email from zoomhash 
499$ new hard to beat that well the $100 shipping was a turn off, i got a cpl used from gawminers a cpl weeks back for $475 shipping included. but definately a decent sale at zoomhash but they need to rethink that offer a bit $459 used versus $499 new well dont see many people buying the used ones at that rate haha BTW these have been selling on ebay all day long for $700+ I am so tempted to buy a bunch to resell them, people on ebay need to learn how to use a search engine

Just picked up two from zoomhash at $499 each I wanted an sp20 farm but those are sold out.
Hi Guys
I've have an Antminer S4 running happily since early November without any real issues.
But yesterday, it didn't want to bootup. I think I've diagnose the problem as a faulty SD card. I've bought a new SD card but I don't have a backup (I had made one, but I've lost it)
How would I go about reloading the firmware on the SD card? I searched but can't seem to find a guide. Or where online can I find image of the SD card?
I stay in South Africa and have sluggish internet so to minimize down time I would prefer not to download an entire 4GB image clone.

Why do you need to reload the firmware of the new SD?
I bought a cpl used and one would not boot, after checking all cables etc. I slide the SD card out put it back in and it booted. My theory the pins on the SD card reader are silver and the SD card contacts are gold. Oxidation due to dissimilar materials. All be it I did not observe any visible oxidation thats my theory, or maybe the contacts were just not seated properly due to shipping knocking them loose?
Who knows but it worked
After replacing the fan, my S4 become like this,,

Anybody can explain me why?only one chain shown zero but asic status normaly.

make sure all cables are seated properly. both on the cards and the fpga board.
I never toucher touch cables cards n fpga sir,, but i wil check my miner,, thanks for answer.

anyone have a guide on pointing a antminer to a QT wallet for solomining? There are several other SHA-256 coins i would like to try to solomine direct through wallet, but I can never connect to them. Only my old USB miners connect to wallets.

Does someone have a spreadsheet they can share showing voltage vs power usage vs hash rate for S4s?
Thanks.

well the temps range for 47c-53c I live in florida but its a nominal 74 degrees F in my house, I am sure the office runs a bit warmer due to all these miners got 6 s3+'s, 2 C1's, and these 2 S4's. These S4's sound like vacuum cleaners fan speeds are 3900-4k
I guess its not the fans making the noise as much as its the air flowing through them. Wish i could afford 3M novek immersion cooling tanks
I am just blown away by the noise of these things 4x as loud as all my other miners put together.
I have them in a rack exhausting straight out the window w/ exhaust window fan so pretty good heat exhaust in place nice and toasty outside the window
Think these things are headed for the garage, probably build a room and have it exhaust into the attic. Bad part is going to have to AC the garage then. (summers coming) probably add a vent to the central AC or maybe get a portable AC then I am also going to have to run some electrical only a single 110v outlet in garage. But since i will be close to the panel shouldnt cost to much. more cost involved in air conditioning the garage, why i think a small miner room would be a good ideal, just have to figure out the airflow intake volume matching exhaust volume
Just cant take this noise in the office its mind numbing. Might have to offload these on ebay and get S5's instead.

You will need AC in the garage.
Give --bitmain-homemode a try, makes them significantly quieter and they run about 5c hotter. Very good tradeoff IMO.
