LED lights come off the boards not the PSU... if it was PSU the WHOLE thing would be dead... clearly something wrong with the beagleboard.....

Are you loosing hash power as a result? If so it would be your hashboard. resetting your miner should temperately solve the problem I'm not sure if its a capacitor on the board which is going bad but something along those lines. I think it would show an x for a bad chip. i replaced caps on one of my miners hashboards one at a time till the board stopped randomly turning off.

Meech are you able to show a screenshot of status page? I have seen it before once on one of mine. I did a reboot and was still there. Actually went and did a power down of PSU and power back up never saw it again. On mine it was not effecting hash if its the same. (It's been a while back I think I put firmware on it again, but I'm thinking the PSU down and up was what made it disappear been a while)

Gauging interest in a compatible replacement fan. Specs on the fan will be almost identical with what you would be able to get on Amazon with the exception of the cord being .45 meters or about 1.5 ft and going to 22 AWG instead of the standard 24. My hope would be going to a larger gauge cord would give the fan better longevity in a mining environment. Cost would be around $22.00 shipped in the continental USA so not a great cost advantage over amazon but you would get a longer connector cord and larger gauge wire. Please let me know your thoughts concerns or improvements.
Second issue is I do not mine anymore so I would need some trusted members (two) to test out the fan if their is enough interest I can have the factory get to work.

I can tell you I have replaced one fan out of my S4's so I have had great luck with original fan's. I ended up putting in a more powerful fan but it was not needed i used this to pick fan - https://bitmain.zendesk.com/hc/en-us/articles/204199879-Antminer-S4-fan-specification-and-possible-replacement-fansThe longer cord is the most nice thing I see. I'm not to worried about AWG as I don't think it's going to burn. I was lucky and it was a close fan to controller. But if would have been one of the others I would have needed to do a mod on fan to get the length needed. So that could be a nice feature for some. I think there is two main tests you need to show. One being just replacing one fan as usual repair. And I would also suggest show replacing all 4 fan's that really would put fan to the test. With replacing all 4 we really could see the performance as no old fans remain.

Not sure if this has been discussed, I checked through many pages and did not see an answer, same here: https://forum.bitmain.com/bbs/topics/1753If there is a power failure to the S4, is there a way to have it automatically turn back on when power is supplied again, without having to hold down the button on the back?

You could do like M's antmonitor and say if it goes under so much hash tell it to restart. But soft reset does not always fix hard reset problems. Also you have to leave a computer open to moniter it with this program. It's worth taking a shot of looking at though.

With a power failure, M's antmonitor will not help as the machine will not turn back on unless you hold the button on the back of the PSU for 3-5 seconds. The SP20 and S5 do not have this issue, it is unique to the S4 PSU.

But the others I have to get up and go power down/up. You are right M's antmoniter will not help if its one of the issues that require a psu power cycle.

Now that summer is here is there a good guide on how to underclock the s4? Is the best way still to go back to 10-2014 firmware and use the below chart to under clock? Any tips to make sure I don't destroy my hardware. https://i.imgur.com/9YY8UCq.jpg

Any tips to make sure I don't destroy my hardware. https://i.imgur.com/9YY8UCq.jpgI would say as far as safest thing is go in small intervals. Don't just jump to lowest setting. I would really watch it closely during it aswell. Make sure no issue get's to out of hand. Just be careful with doing it is my main advice. As it was removed from newer firmware.

Any tips to make sure I don't destroy my hardware. https://i.imgur.com/9YY8UCq.jpgI could never get my "experimental" S4 below ~0.6W per GH/s. I think setting voltage under 0.68V or so would prevent it from starting. I'm not sure if that was just one bad apple or a general problem with S4s but just saying - don't get your hopes up, that chart might not work as advertised ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

The good thing about the S4 is it using a SD card. I would suggest using a tool such as Win32DiskImager to take a backup of SD card before. The if it does have software problem with low power you can flash old settings back via SD card.

If you are willing to lose some GH/s you can set an S4 to 1350 GH/s @ ~820 watts. There are many different settings which will achieve this.
Plus; the shitty S4 fans will last longer.

I have actually had pretty good luck with my fan's. I ran with a OC on 3 for a long time. Then summer came I went to stock freq. So far only 1 fan has needed replaced. And I'm sure my OC didn't help. So I have had really good luck.

Hi All
Have been running my S4 (Batch 2) at 2T/H happily since March.
Just yesterday it shut down and will not restart - just get the flashing red light at the back indicating a fault and amber light on.
Was not aware of it operating above 60deg.
Any suggestions where to start when I open it up as I assume I will have to do.
thanks
