Why not just use these little guys?

I use some milled copper heatsinks very similar to these (or the 1,000 others available) and like them muchly.

As for "bracing" them against the case, bad idea to create new paths to ground.  Also, more noisy badness.


Good point- I cringe just thinking of copper scraping up against the case...  causing some non-loctite-coated screw to come loose or something  Tongue
Even if there were something insulating them (like eight non-electrically conductive thermal pads placed on the enclosure), it'd be a bad idea to have that tight a fit on a first run.

During the first production run, maybe it's best to just stick with the thermal adhesive copper heatsinks (<--pun) that may or may not fall off over time.
If BFL doesn't install them, I will do so on mine  Grin

Haha, seeks like a little bit overkill but thanks for the idea Wink.

Many of the shipping FPGA Singles have a passive heatsink on the bottom already. I was just suggesting that  a similar approach could be taken (by BFL) for the SC Singles.

True that, hopefully BFL will do a similiar approach. But its always nice to have a backup plan if they don't Wink.

We should be keeping the price paied in mind when it comes to what kind of fan/heatsink/case combo they come up with. I'd like my money on the heatsink.
i dont NEED a case, And i Can replace a fan..., Dont know how the hell i'd get a new BFL heatsink

I think they should go all the way and design a controller. Something like 16 USB ports of something crazy. Then jut arm and 256mb of ram. Then code some really basic Linux onto it and a ssh server. Then you can remote control it. Or scratch that. A device that supports daughter boards. Then you could buy 1 chip daughter boards,2 chip daughter boards etc etc etc.

Stolen from https://forums.butterflylabs.com/showthread.php/251-More-Jalapeno-Pictures-amp-Shipping-Update

Quote from: BFL_Josh;
Attached are some more pictures of the Jalapeno.  It's in one of it's prototype homes, but the design is changed and we are waiting on the updated box to be delivered now.  However, the fundamental design will remain unchanged, just some cosmetic changes (laser etched top, no silver, etc...)

We are not going to make the first half of November shipping goal.  Right now, I want to say fourth or fifth week of November, but lots of little issues have cropped up, pushing the shipping date out a bit here and there. To be on the safe side, I would estimate the end of November / beginning of December as a likely ship date.  We've had some trouble sourcing the VFD screens for the Minirig SC; the wharehouse told us they had about 5x as many screens as they really have on hand, so we are coming up short.  The good news is that we've come up with an alternate solution that is so full of awesome, I am going to save that for a later update. It is, however, necessitating a redesign of the Minirig SC case, though it won't really affect the timeline in any material fashion, as it's just one part that needs to be changed a bit to accommodate the new screen.

We are also still waiting on the HSF for the Single SC to show up - the factory has been a bit slow in that department, so that set things back a bit. 

We expect the final chip versions to be in our hands in ~25 days, with final assembly and shipping to begin a few days after that.

I'm pretty sure the Jalapeno will only have the one chip pictured...  Not sure how it will be cooled though...

We don't need silly pictures, we need a demonstration of the chip doing the actual hashing! even if it is an early prototype with a few percent less performance!

Ah I see. As an employee, you must have intimate knowledge of their processes to make such an astute statement, correct?

Oh, what's that? You don't work for the company? Instead, you have felt the need to add nothing of importance to the current conversation?  Roll Eyes
Yeah, that makes more sense...

If I remember right they said that the casing would be the heatsink.

The brains behind BFL, it would seem.

How do you suppose he hooked up with them?
