Incredible thread, thank you lightfoot for your insight and a question if I may. Little singles out in the open with a big fan blowing at them should be fine, right? my temps are also reporting around 70 degrees (which happens to be the ideal temp for my jupiter, so I thought those temps were ok. ambient is 90 f poor AC is going full bore just to keep the room at that temp. The thing is, when I finally got these little singles, I took one look and stripped the cases and threw them and the power supplies away. they didn't even include a fan for the heat sink! one fan only and that is the intake fan, which is terribly constricted by that ridiculous face plate and I thought "I can do better" So I stripped them down, set the intake fan on top of the heat sink blowing down, and that blower fan blowing across them. And a question for the OP please. How long was it running before it blew? |

Incredible thread, thank you lightfoot for your insight and a question if I may. Little singles out in the open with a big fan blowing at them should be fine, right? That could work. I haven't played with the LS yet, but I would say the key is to get a fan on top of the heat sink and one blowing from the side over those FET heatsinks. Running even a little vornado on mine is keeping things cool.  The thing is, when I finally got these little singles, I took one look and stripped the cases and threw them and the power supplies away. they didn't even include a fan for the heat sink! one fan only and that is the intake fan, which is terribly constricted by that ridiculous face plate and I thought "I can do better"
There's only one fan? Blah, I thought there would be two. Ok. C |

Can I just butt in and ask what spec the BFL 120mm fans are inside the single, I am running one outside the case currently in a cold loft and want to get new fans on it and the case back on (originals broken in transit apparently and I don't have them)
tried some noctua 1.44W 0.14A things the guy gave me when selling and they're hopelessly underpowered.
TIA, and good luck OP.

try the Nidec Servo (Scythe branded) gentle typhoon 1850s finest fan I have ever dealt with http://www.sidewindercomputers.com/scge120mmsic2.html |

OP is there any BFL warranty? or had you manipulated the single in any way that voids a warranty? I have often wondered about this, seeing how shady BFL was originally with their delays.

here is my 60 single's new trick, it will run about 12 hours at rated hash, then starts slowly dropping speed. Used to be it took me a few days to notice because it happened slowly, now I will be under 40 in 24 hours and I am rebooting it daily.
anybody heard of this one before?

The software load on the LS is really sensitive to temps. Check to see if any of the fans are blocked or down, if you really want to I can take a look at it, drop it in the mail.
Speaking of which I bought a 23.5gh LS that I have boosted to 28gh. Can be done just need software and heat sinks in the right place.

temps are stable while it is at full speed, then temps drop with hashrate, if it was thermal I would expect dropping hash with stable temp
I think software, was hoping it was a known issue

Hm, you're right. Does the power supply get warmer? When the hashrate is dropping, what do you see per chip by doing D, then M to switch to per chip stats? I'm wondering if chips are dropping, or the clock is dropping. Post and let us know. |

I had troubles with my single, wrote BFL for a RMA and within 2 days received an email asking for my original invoice # and email. I wrote back telling them I bought the unit second hand and did not have that information. Within another day received a RMA. I sent the unit in and received a single back in about 1 week. It appears they just removed my cover and placed it over a brand new unit. Really overall great service.
I also have another single that acts the same way of slowing down after about 12 hours. I just stop and restart the easy miner and it goes back up to 58/59GH. I think it's either software or memory problems with my desktop.
