Since the warranty on most, and not exluded this, bitcoin miners are short, what would be the main time before failure?(MTBF)
How long does it on average run until it probably stops. MTBF, build to run..for how long? Under decent circumstances?

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-fans
I 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.

Thanks for detailed instructions
Glad to see Sanyo does the job properly... 
Thanks for the info. 
Fill up that 80A of usable power! 
I'm limited to 90A right now, soon to be 200A.

I'm on a family farm house. So it was designed for lots of electricity. I have a 200 amp going to house, and 100 amp subpanal going to area I'm now setting up. So total of 300 amp already
. Just hard to justify that much mining gear currently for me.I've got a 200A feed to the house, with 60A going to a sub panel in my detached garage.
Is your 100A sub panel feeding off your main 200A from the house? If so you don't have 300A, you're drawing 100A from the 200A available.
To have 300A, you'd have to have a 200A entrance to your main panel in the house, and a second 100A entrance to a different building feeding that building's main panel.
I have 300A. There is 200 on main panel. and 100 on the one going to garge/work area. It was wired for a farm. Some of tractors and stuff in winter or cold you plug into the electricity to keep engines warm and easy to start. So it was designed with farming in mind.
At this point the farming and cattle land is rented out. I went the way of computers not farming business.
Lol that would be true. But farming inside compared to out in a field is much nicer
. And if you think miners are expensive just go look at farming equipment.... it is crazy.Sorry if it got off topic because of me. Back to regular programming.... i did S4 fan replacement and working great now! - https://bitcointalksearch.org/topic/m.11250003

. Just hard to justify that much mining gear currently for me.Have two electrical lines going to the electrical box. I would love to turn the old barn into a mining area up top, but I could not justify the install costs with having the area I'm moving miners pretty much set up. Biggest thing was some wiring, and now proper fan and exhaust setup.

Is the S4 able to control the San Ace's RPM? Or is it always running at 100%? Must be loud as hell at close to 6K RPM.
What are your ambient temps? Seems to be running pretty hot for the speed those fans are spinning.

It is able to control it. I have been working on setting up a new mining area so it's been running in 80 F or a bit higher then it normally does. They are being overclocked a little bit as well. It does always spin faster then standard fan though. If you want one closer to original there are some good delta's.
Below is with some of the fans better positioned and it being colder and at night
I'm hoping to get all my miners in the top of a garage/work area. Slowly I'm working out the kinks and should have all my mining gear there eventually. Have 100 amp just for miners almost so lot's of possible expansion. Currently only using around 10k watts.

Why didn't you just swap the plastic connectors on the fans? The pins are easy to disengage and remove. The metal part looks to be mini jr. molex on both, would be a direct swap.
If it was a longer one this would be route to go. As cord is not very long on the sanyo. But I had tools sitting there from electrical wiring so I was able to make that one fit in less then a minute. It also is a nicer cord with some shielding, I wanted to keep it personally.
Very good question though.

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.
Thanks for detailed answer... Did you need to modify anything to connect fan or is it just plug and play?
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.

notlist3d with the fans spinning faster are they louder or quieter?? oh and did it reduce the heat on the boards by anything noticeable??
also what mining group are u mining with to mine at 16.4k diff??
Sorry now im being a pain.. was ur S4 a B1 or B2? I have a B2 that i got on December 20th so i'm trying to work out when my fans & psu are going to die..

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 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.
