Goddamn...apparently, their assembly ninja is slow as fuck.
I believe it's referred to as "testing". It's usually a good idea before you send out a product. Got your order in yet? You must have as you're so concerned about delivery  If I wouldn't get banned for posting an animated gif of a guy masturbating in a gimp suit in response to this, it would be there. Judging from the past four months, they aren't big into testing... |

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

RoloTonyTickler: note the date on the posting of these photos. How much testing is necessary? |

If they wont to test all of them 1 by 1 by that same guy 24/7 ... :/ that could take somme It`s quite big...comparing to Yoda  |

Dunno mate. I assume they just want to get it right. Not sure we should be having a go at them for that. |

Does anybody have any info on that company and the people behind? Doesn't the company have a publicly listed director? Why the secrecy about the last name (K)? I am a bit unfamiliar with the US system, but is there no company report available online?
I apologize if this was already covered in one of the previous threads on BFL, I only read this one.

Yeah it was covered but the threads are way to long and have been trolled to hard for any sane person to read. They claim to be a company but have not given any evidence to support this. They claim to have registered online in the state of Wyoming as a company but this can not be verified. Many of their claims like being Incorporated are just flat out lies. So it doesn't really help that the registered agent resigned a few days ago and the RA status is now listed as 'Delinquent' at the Wyoming business registry? |

Dunno mate. I assume they just want to get it right. Not sure we should be having a go at them for that. I assume that testing should have been done before they ever advertised their product, but alas... |

 So yes, that's an extra fan attached to the unit underneath apparently. Sonny said they're happy with the stability but they're erring to the side of caution and the extra fan may be removed for further production runs. I'm OK with the second fan, can't hurt can it  |

Hmm - sorta kills the stackable idea ...
Edit: actually the vent on the top definitely kills that idea (with the fan on the bottom)

Whats this fan doing in the bottom. it`s supposed to be closed box just with the fan upside and somme holes in the back and left and right side. strange....
those fan`s are120x120 ??

If anyone has read Quarantine by Greg Bear ... thats what the box reminds me of. Can people suggest (via PM) the most informative posts from the first thread to add to the top post here? I'm going to go find some now. box reminds me of the I.T crowd where they are showing off the box thats the internet |

That looks like an 80mm fan to me.

If you're searching these lines for a point, you've probably missed it. There was never anything there in the first place.

I've not seen this second fan so I do not know, but is it because the unit is getting too hot? What is too hot for this type of tech anyway?
110C but that is internal junction temp. These type of chips tend to have poor heat transfer so the internal temp can be 20-30C higher than surface temp. Still the cooling design seems to be a sub-optimal and my guess is the result of the company already buying hundreds of cases, fans, and other components for a 20W which will never exist (well outside of flawed simulations). Someone correct me if I am wrong but I would imagine a high density pin heat sink on the two FPGA and then a larger fan mounted on the side blowing across both chips would be more effective. You are getting a higher airflow, and it is better directed at the actual heat source. The unitary airflow would also allow more even cooling of both chips. So IMHO : The bad news is they are salvaging their existing inventory of parts resulting in sub-optimal cooling. The good news is is more evidence that they are just poorly run enterprise not a scam. The super good news is for people who like to tinker one probably could come up w/ a custom cooling solution which is more effective. A side note: The higher heat load and higher MH/chip makes watercooling interesting. Putting a $50 waterblock on a 8W FPGA (Spartan-6) is kinda silly as even a tiny fan can keep temps at optimal. Watercooling isn't going to improve thermals much, and since you are only getting 200MH/chip that adds a hefty $0.25 per MH in cooling gear. A higher output chip, especially one running hotter makes water cooling more "interesting". Honestly my impression of the product improves as my impression of the company declines. The reduced specs, delays, plausible sourcing (BFL drop that "blend of ASIC & FPGA" from your website it just makes you look stupid), and "bolt on fans" seems more inline with the type of enterprise which could source some last gen chips than one that would be making custom ASICs or current get sASICs. So I may buy one just to fool around with the watercooling potential. Of course they would need to start shipping some product first so likely I just have to wait another .... (wait for it) .... 4-6 weeks. |

those fan`s are120x120 ??
In both the original enclosure and the new enclosure, vents were only on the 2 sides (and top, obviously). The front has the power LED; the back has the USB and power connectors. I was assuming the side vents were for exhaust, but they may just as easily be intake (with the top fan blowing out) ... The original fans were 80mm; the new enclosure is larger and has apparently moved to 92mm fans. The bottom fan in Simonk83's photo looks to be 92mm since it follows the screw holes of the top 92mm fan. They are NOT 120mm and they appear to be too large to be 80mm fans based on the new enclosure dimensions. Yeah, I'm with D&T on this being a sub-optimal design. BFL seems to be trying to salvage the situation with their '4x power dissipation surprise', using whatever off-the-shelf parts they can. No one would purposefully design a product like in the photo. It wouldn't surprise me if they are already working on a 'Rev 3' redesign to address this, though obviously the early adopters would not reap the benefits. |

Looks like a new heatsink. If they have any sense, the board is now mounted sideways, with the top and bottom fan working to together to blow air over the heatsink in the direction of the grooves. If the bottom fan is mounted to blow against the underside of the PCB, then, well, I cant imagine anyone being that stupid.
