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).

None of mine came with an 80mm mounted to the bottom though.

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!

this fan sounds like a mixer...
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
Those are the ones that came with mine, actually. Or if not the same, extremely similar. I can't be arsed to take it apart again just to look at the part numbers.2700rpm

Although, some people have been reporting different fans. I would like to something a little better, but that still fits in the case and fits on the singles fan port.
Can I ask WHY?
The description for the video reads:
"So I set my Single down on something sticking up by accident one day, and it caught the spinning fan blades and broke them off. I decided to fix it myself."
Here's side by sides of the fans:

Curse you RJK!
That's amazing, though letting it suck shit up probably isn't very good

Does it take off and float around the desk, or have you bolted it down?
Can I ask WHY?
Does it have vibration dumpers, vibration might not be good for the solder on any component above 60c.
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!
