I added a bit of cooling to the side of each chili, so it blows air across the VRMs on top and bottom of board, I also have the exhaust from the heatsink deflected down onto the VRM section, using cardboard. I think the side cooling(implimented last night) has allowed a tad more speed, I really want to try heatsinks on bottom of board. Im waiting to see if I ever get them from the guy I bought this miner from...lol!  All but 1 of them run 37+GH @ an avg of about 55-60C... one of them is an oddball, 35.6GH @ 65C (tried reseating heatsink several times w/ no improvement) 3 of them run 38GH+ and one of them has been up to 40GH+ several times....wish I could stabilize it that high, but it clocks down. |

Heh, I love the overkill with the triple fan Arctic Cooler. I need to pick up one of those for my R9 290, that thing wails as bad as a BFL Single when the fan spins up.

You want to make sure that you arent using 2 PCIe connectors on a single cable, that is easily overload for just a single cable. I tried that for a few mins to see how hot those cables get w/ a 400w load and it was HOT! =P |

all day today and most of the night last night i have been dealing with 4-6 out of 12 chili miners going sick about every 30-60 minutes. they come back as soon as i restart bfgminer but it is getting tiresome to restart it all the time. i had them all running non-stop for at least a week before this using the same setup. any ideas?

they hosted by an rpi? if so... mine do that every once in a while, usually within 3 hours of fresh power up... if its gonna even happen. I find just moving USB cables around, fixes the problem more often then not ...
theres reports rpi cant handle many USB devices well...

I despise the 290 reference. It's like owning a jet. The triple fan AC actually performs just as well as a Mono Plus. Save your money or get the NEW double and triple fan models. |

Enermax Revo 1350 W has 6x 12V @ 35 A. 4 of them are connectable by PCI-E. The 5th on a different rail is from the EPS12V line so I used a "good" well enough copper diameter extension which I cutted and assembled an PCI-E as an adapter. I've never found Adapter for EPS12V -> PCI-E. The 6th rail is on the 24pin ATX plug. I have an extension only with low copper diameter. So I will buy an good well copper one and will try assamble an PCI-E again. Also I did this for an 1500W Enermax Platinum (4 PCI-E Rails on knc Jupiter, 5th EPS12V via adapter to one chilly. Missing one adapter for 24pin ATX) The Enermax 1000W Platinum looks like the best for this because you don't need a special adapter. You can add 5 PCI-E cables because it has only one 12V rail for 996 W. The ones with higher rates e.g. 1500 W have 6 rails with only 35 A each. Also I use one 550W Enermax Revolution87+ on PCI-E, one on EPS12V with 3 low performers. It could be hard on limit, but is stable working for the moment. Each single rail can support 25A, but generally not more than 45A. Also I use one Thermaltake Smart SE 730 (3 rails 18 A on 2 PCI-E + 1EPS12V). Edit: In my opinion the best is to use an mono rail power supply because you lost to much A on different rails or the rails did not have enough A to support 2 Modules on one rail :-( I have an very old Enermax Noisetaker for 600W. It supports 2x18 A, one on PCI-E and one on EPS12V. I use this for tests of my boards. I guess your PSUs have no output electronic fuse which emergency shut down the psu. I killed also one old style psu :-/ which was allready in my electronic trash bin. Now it's back in the bin but without the internal cooler which is still usuable. I recommend to us an psu which has no problems with overloading an save themselve. I've allready two defects on enermax psus but never there destroyed my connected hardware.. So I feel to trust them. But I think also there are better ones on the market ;-) |

check the cooler mounting for good contact with the chips. Then use the "Chili Fash utility" to check the device. It sounds like only half of your chips are running. MrTeal posted the utility on "dropbox" earlier in this thread. |

This ^
I've only ever seen a temp reading above 70C when I had lousy heatsink contact and the Chili was trying to hash faster than it should have. If you're not using a backplate I'd recommend one as it really minimizes the board flex and ensures you've got good contact on all 8 chips.

In bfgminer, hit m to see what the voltage is. If it's below 1v, you have cooling issues. |

So I have noticed, when my cards go "south" I have no way to remotely reset them... I have to turn them off, wait for the chips to cool enough to self test ( usually 20 minutes) then turn them back on. And often times, I have to do this with my Pi's off, so that they don't issue work to the "off" miner while its self testing.
Has anyone come up with a way to do this remotely? I have the opportunity to move my mining to my work, but before I do that, I need to understand if there are any terminal or other ways to force the miners to cool down, and truly "reboot" themselves remotely.
Thanks all!
