Every time a block is mined, a certain amount of BTC (called the
subsidy) is created out of thin air and given to the miner. The
subsidy halves every four years and will reach 0 in about 130 years.

I have the fan problem too on one of my antminers
its only a month old and the fans wont go over 3k so its limited at 1500 or so hash rate
Are they the original fans? If you bought it from bitmain then they should be but some people replace fans with low specs. Either that or your fan is slowly failing.

No problem, enjoy! The firmware works very well, as do all of smit1237's firmwares. (he made this firmware for nicehash)
Does Smits firmware fix the p=x.xxxx problem for switching pools from nicehash. Thanks in advance Of course it solves that problem, if this firmware listed on nicehash... Actually it doesn't, unfortunately. If p= is set below whats being paid, it works, but if p= is set above the current price it doesn't switch to the second pool. It just stays stuck on nicehash, not getting any work, and not getting work from the second pool. It just idles. Hey Prelude Thanks for the S4, Works great. BTW a way i avoid all those problems, "extranouce, Pool not changing etc." is by using a Proxy server. i use the one posted on nicehash. easy to set up and works nicely.

So, if price settings still doesn't work, please ask nicehash to fix that, i've used latest patch from them.

Sadly have had my first fan quit. These S4's have been workhorses. This is first problem I have had with it. If I would not have been moving miners I doubt I would have known, the fan half way still spins.
Ordered a replacement fan should have it mid week. I will document it and show how well it hopefully works. It was far out of warrenty so I went with replacement.

Great choice, I think that Sanyo will do the job. Please post here your tests and conclusions.

I should be getting the "Sanyo Denki SunAce 120 9GV1212P1J091" fan tomorrow. Has anyone tried it?
I'm wondering if it's plug and play. Or if I will need to do anything to fan or wiring.
Thanks!

Well if we look at specs on Sanyo it should be plug and play... but there could be a case when you would need to connect it directly to PSU. You will see when fan arrives.

I will upload pictures "Sanyo Denki SunAce 120 9GV1212P1J091" is good for my needs. It was a fan close to board that stopped working, had it been one farther away I would have needed to expand the wire length. Also there is a plastic part for 3 pin setup on the sanyo cord, i filled it off so it fit clean against the 4 pin on board.
It does spin 1500 RPM faster the the regular fans. So far all is looking good. But I will monitor it.

Here is what the stats look like with the sanyo fan. It is circled in red you will see it does have a higher RPM. I think for the money was good deal. Cheaper then Delta and faster then delta. Now I will watch it over time to see if it lasts good.

I believe mine are B2's. I know I waited just a bit and I want to say very early batch 2. On sound I cant really say. Currently I have some of my gear sit up in a top story of my garage including this one. I'm working on wiring more circuits it will have quite a few miners out there. Mining BTC trying a site the varidifficulty seems to set difficulty high. I will get some pictures up tomorrow.

I'm going to make a thead to show the steps I did. You could "force" it on but it pushes the white plastic connector more then I liked. There is a spot on it I believe made it where it could do a 3 pin easy, as and also do 4 pin. I used a knife and file to get rid of the 3 pin guide on the plastic. It worked the file is a little slower method but it makes sure less chance of messing it up.

Replacing S4 Fan First make sure you are out of your warranty as replacing fan violates it. (Warranty is 90 day's so it's a good chance yours is out of warranty). Then look at Bitmain suggestions on fan's - https://bitmain.zendesk.com/hc/en-us/articles/204199879-Antminer-S4-fan-specification-and-possible-replacement-fansI personally chose the Sanyo Denki SunAce 120 9GV1212P1J091 Stats from Bitmain: Dimension: 120*120*38mm Voltage: 12V Power consumption: 6400RPM 36W Rated current: DutyCycle 100% @ 3A Air Flow: 6400RPM @ 224CFM Noise: 6400RPM @ 64 dB-A Air Pressure: 6400RPM 36.82 MM-H2O Life Expectancy: 40000 hrs @ 40°C Connector: 2510-4P Install: You will unscrew the 6 screws holding on the top of the case. Also unscrew the fan metal guard with 4 screws this will release old fan. You can unplug the old fan from the board. The new fan: One thing I ran into was the new fan had a plastic piece for allowing it to set up on a three pin fan assembly easy. I used a file and pocket knife to remove the 3 pin plastic. This allowed me to put it in the 4 pin slot on board without pushing the plastic far away from plug. Also mine was a close fan to the board. If your fan is far away you might need to make the power cord longer for the fan. Comparing old and new fan: Gallery: http://s100.photobucket.com/user/notlist3d/slideshow/S4%20Fan%20Replacement?sort=3And of course the end result:
