hello, here is my power supply unit that works for my S3 has 500GH / o board  that image is way too small to see anything useful |

While I had a board out I looked for two things, a) the date on the board - not found so must be under a heatsink, b) the IC id on the chip under the fan connection above to the left of the end ASIC. The print on the IC was unreadable. Next time I have a board out I'll take it into the sunlight with a loupe. I'll put a ohmmeter on any associated resistors and compare to another board. In situ measurement of caps often is impossible but I can give that a try as well.

What's your opinion on the Corsair RM1000 ?
Hi!. In my opinion, the Corsair RM1000 is the best power supply. I installed it with 2 S3 with OC 250 and 256Mhz and perfect. The S3 are hashing 510Gh more or less. All the cables are cold and the fan of power only run a few times. Regards. Antuam. |

hello, here is my power supply unit that works for my S3 has 500GH / o board that image is way too small to see anything useful sorry  Wow that is really good hashing. Is that an S3+ or an S3? |

It's happily powering my two S3+ units at stock settings. |

I wonder. If facing the RJ45 connector the hashing board on the right is the top row of o's and has the higher temp's, then it doesn't follow that the temperature sensing chip is there under the fan connector as that's the cooler end of the device.

Out of 9 unit I have about 3 that have fan problems,
One was at 100% on arrival.
One became intermittent 100%.
And now one became permanently at 100% . I heard it ramp up to 100% and now no amount of power cycling will fix the problem.
What's up with that ?

received my 8th batch S3 not even one reaches the 500Gh/s range best is around 453
not happy!!!
Dude! you have to overclock it if you want 500Ghs At stock 450 is right where it should be. |

What does the GUI say 100% fan maxes out at? |

You could determine if there's any responsiveness at all by putting a fan forcing air in and later put the fan to suck air out, fans outboard the installed. Still if firing up a cold S3 shows max speed then it's not likely to change. |

Better thermal paste spreading means slower fan and lower HW errors though not always fixing a declining hashrate. Slower fan means more economical running. If the thermal paste isn't spread well under the temperature sensing device, where ever it is, it will take a higher fan speed to lower its temperature.

lol, my package with 2x s3+ batch 9 WAS in the Netherlands but somehow went to freakin Belgium! FU DHL*  * On a positive note: since DHL wouldn't have delivered it before monday anyway i'm hoping they'll correct their mistake before then. |

Interesting. The problem hashing board now in my first S3 is working fine and very stable. I just found there is a difference between my first well running S3 and the S3 that the problem board came out of, and that's is a different firmware on each. I haven't found a way to determine while ssh'd in, e.g. opkg list | grep antMiner comes up a blank. But, bruno033 pointed me to the firmware page and I see there the 0721.bin has a solid green light when running. The first S3 from the mid-west has that. When I saw that the S3 from Florida had a flashing green light when hashing I though I probably configured it differently than the first. But it must mean the S3 I got from Florida has the 0711.bin firmware because the other later options are the 0811.bin and the 0826.bin, both of which will have the Advanced Frequency change option on the miner configuration page. So, the questionable board is very stable at this point in the S3 having the 0721.bin firmware. Time will tell if it remains at 441 overnight as the humidity rises, e.g. right now the rh is 30%.
