Of course you guys are fully satisfied with your rigs, you have to be.  You plunked down treasure, waited seemingly forever and finally were rewarded with gold in a box.  You better be satisfied by this point.  Wink

The perspective from the outside though is that when one plunks down 15grand or better yet 30+ as you both have shown along with darkice that you get something that is a little more polished as well as 'just works'.

My thoughts are that they just don't have the time/resources to put a nice coat of polish on the insides as they are constantly in the innovators seat which moves fast. I don't imagine we will see newer revisions of these rigs because ASICs are getting closer every day supposedly and that will be a whole new ballgame.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

perfection === iteration

Do you think the ASIC rigs are going to use multiple PCBs in a box? If so, it's the next iteration of the previous design.

I am not even looking for perfection, just a bit of elegance that shows some thought and love went into the current box. Kiss

The next go round will be the next go round albeit cleaner I hope.

That's interesting; so they are using USB hubs instead of the "X-link" board that we saw that has SATA connectors. I wonder if the SATA is for a different application or if USB was deemed more reliable or what.

Of course not.

I am sure that BFL were initially planning to use the X-link board and Raspberry Pi to make a much more polished mini rig, and then decided to do without them in order to cut corners and not be (more) late on their schedule.

I'm not quite sure what you guys are expecting.

That's a thought I have quite often on this forum.

Just take off the case and mine without it. My bottom fan died after about one month of usage Undecided. At first I was pissed about the quality and that I had to fix it but the show must go on. I like them better naked...


Are the temps lower or higher with the case off?

I can't stand the misalignment (random disconnects) and would happily shed the case if temps are same (or lower).

The temps are lower with the extra fan. I also turned the top fan around.

It's pretty clear that some guys are simply using these forums to turn a quick buck in any way possible.

Not sure if serious or trolling.  Roll Eyes

I need more mini rigs to run Gigamining. Pure and simple.

Top fan blowing down should be more effective I believe, any guess on the difference in degrees ?

Problem is that temps change with the bitstream you use. The 120mm fan from the side is making the main difference. About 3 to 4 degree C less.

Hey BFL, my single's fan is making really annoying noises that don't sound good... Will replacing the fan void my warranty/ability to trade-in for the SuperComputer Single I bought? If I am allowed to replace the fan, any one in particular you would recommend? (Right power draw, etc.). Thanks!

One of my singles has a top fan that seems like its slightly unbalanced or something. It runs hotter than the rest and has a vibration to it when I hold it while none of the others do. I'd be interested in the same answer. I think I could find a fan locally. Any particular specs for it?

Thanks

The top fan is a standard 92mm fan running at 2,500 rpm.  If you're having trouble with it, you can either send it in to us for replacement or swap it on your own.  Doing this sort of work is straight forward, but please be careful not to shock the board.  Power everything down before you open the case.  Unless obvious mishandling is responsible, simplly opening the case and swapping the fan will not void the warranty or alter it's trade in value.

If your unit is making a noise, that is much more likely to be the smaller underside fan which is either copper or silver in color (depending on your unit).  You can try loosening the lower screws to relieve pressure on the fan...   or just try setting your Single on it's side...  that will almost always arrest any unwanted sound.

What is the amperage draw (& cfm maybe) of your stock 92mm fans??? So we can match them accordingly.

Thanks  Grin

Thanks for the info! What would the turnaround time look like for sending it to you to fix? If I forget/place in wrong one or two of those rubber washers, that won't affect trade-in value, right?

Upon further inspection the problem does lie with the bottom fan. It appears the middle of it is not even... When you look at the middle of it while it is running you can see it wobbling... mrb, will your solution fix the fan's center itself wobbling? Thanks!
