Title: BFL Single + Delta = Whoosh! Post by: 1l1l11ll1l on May 15, 2012, 05:05:50 PM Standard motherboard risers were needed to get it high enough over the heatsink. This is the first release of the BFL single
Using Delta fan, Dell P/N P2780. Running it at full speed, simply connected the black to ground, the red to +12v from the computer's Power Supply. @ 2.5a I'd not recommend connecting it to the BFL single's fan port! https://i.imgur.com/dC7gD.png Title: Re: BFL Single + Delta = Whoosh!

Curse you RJK! Title: Re: BFL Single + Delta = Whoosh! Post by: cuz0882 on May 16, 2012, 08:35:44 AM Hopefully that's going to a fan controller.. I take it the 92X92X38 does not fit inside the case? I've been waiting for someone to say the max amps we can run off the single fan connector. I was thinking this one would probably be ok, plus I should be able to sleep at night. http://www.newegg.com/Product/Product.aspx?Item=N82E16835705011 (http://www.newegg.com/Product/Product.aspx?Item=N82E16835705011)

Or if not the same, extremely similar. I can't be arsed to take it apart again just to look at the part numbers.Title: Re: BFL Single + Delta = Whoosh!

I would like to something a little better, but that still fits in the case and fits on the singles fan port. Title: Re: BFL Single + Delta = Whoosh!

;D Title: Re: BFL Single + Delta = Whoosh! Post by: e21 on May 17, 2012, 05:43:15 PM Is the new cooling solution on the revision 3's still not sufficient to keep the Singles from throttling in an average environment? Say 23* C?

All of my 10 came with a bottom fan. It's just a little 40mm thing inside the bottom of the case though... not sure why people are making a big deal over it. Regardless, they all stay below 60c, and none of them throttle. And now I only have 4 of them left, and they're running even cooler (more space between them).Title: Re: BFL Single + Delta = Whoosh! Post by: e21 on May 18, 2012, 07:02:17 PM Is the new cooling solution on the revision 3's still not sufficient to keep the Singles from throttling in an average environment? Say 23* C? Correct. Some are still shipping with a bottom fan bodged on. At least they didn't take a sawzall to the case as they did with gigavps's first Rev 1. :) While this is definitely a BFL design issue, FPGAs are notorious for thermal inconsistency across the same chip type and program. I see; I am just entering the field of FPGAs and am expecting my first BFL Single to arrive this afternoon, so that is useful information for me, thanks! Title: Re: BFL Single + Delta = Whoosh!

None of mine came with an 80mm mounted to the bottom though. Title: Re: BFL Single + Delta = Whoosh!
