yes, the item was imported for personal use. I'm no expert in this area, but there should be not much of a difference whether importing them for personal or commercial usage? As they did not understand the mining discussion I started to talk about the calculation of hashes. This way they got a better idea of what the board does.

hi where do u live in eu ? im very interested to start mining with the singles (have a small house), but dont wanna go at the customs and pay extra VAT:s and talking what that box does:(

are there still 6 week delivery time ?

Shipping time is still much longer than 6 weeks. Watch this thread for an idea of what BFL is actually shipping and when:

https://bitcointalk.org/index.php?topic=77796.0

BFL has only started shipping early February orders. They are currently 11-12 weeks behind, but that's better than where they were a month ago. That's only the shipping time. Actual transit time from Kansas to EU, through Customs, to you would be at least an additional 2 weeks (it is 8-13 days to Canada, for example).

from your linked thread .... time from order to ship date = 76 days => 76/7 = 10.9 weeks - 6 weeks = 4.9 weeks late .... definitely not as promised ... definitely have room for improvement ... however not quite 12 weeks late Smiley

Sorry, I meant to say they are only now shipping orders placed 12 weeks ago (latest shipped order to April 23 was from February 1 ... 12 weeks ago). But, yes, BFL says 4-6 weeks for shipping. So they are currently 6 weeks behind their 4-6 week promise. I ordered back in early December and waited much longer than 12 weeks, so it is nice to see they are finally (albeit slowly) catching up with their backlog.

I live in Germany. But there shouldn't be that much of a difference at customs and the usage of the EU-wide TARIC numbers.

Just an FYI on the fan used in the Rev3 Singles (single fan, heatpipe):

Sunon ME92251V2
2700 RPM
45 CFM
32 dBA

The Sunon is a pretty loud fan. Those with visions of keeping these in a bedroom had better be hard of hearing. In comparison, the earlier dual-fan Rev2 Singles had quieter fans:

Panaflow FBA09A12L
2100 RPM
43 CFM
27 dBA

The Rev3 units do seem to run a few degrees cooler than the Rev2's, but that is not unexpected due to the more powerful fan. I'm not sure the heatpipe design has bought them anything in terms of better thermals; the same temperatures could be achieved by putting the Sunons into the original Rev2 box.

It is evident from prior posts that BFL has been shipping several designs of Singles (some with copper heatsinks, some with blue heatsinks, 2 fans, 1 fan, an internal 2nd/3rd fan in some) so the fan models mentioned here may not apply to all Singles out there.

On the subject of thermal throttling, that threshold seems to be different for each Single. I have Rev2's that will happily work at 75C before throttling. I have a Rev3 (heatpipe) that throttles at 65C. (temperatures as reported by cgminer). I'm not sure what to conclude from this yet ... other than YMMV.

Considering the 5870 I use generates somewhere between 42 and 64 dB, I'm not particularly worried about a fan generating 32dB.  In fact, white noise, like the kind coming from fans, helps me sleep better anyway.  Wink

That was my thinking. Heat pipes are great when you need to move the heat output to a different location so a larger fan will fit. But their heat pipe design doesn't move the heat any more than a large heat sink would.

I will say this: the Sunons on the Rev3 Singles, though loud, do have that alluringly sweet sound of a fully stocked datacenter humming away!  It is a high-quality white noise. Wink

A few days ago I replaced the fan of my Rev. 3 unit with a 'Noiseblocker BlackSilent Pro Fan PE-P - 92mm'. Temperature now is stable at 58°C - 61°C. There is no throttling, average speed is at 820Mh/s. The solution is not perfect as you still can't sleep right next to it, but it is much better than before.

There is no throttling, average speed is at 820Mh/s. The solution is not perfect as you still can't sleep right next to it, but it is much better than before.
Thanks for that; a quiet fan puts the Single in a totally different light. I've experimented with the following fans on my Rev2 (dual fan) and Rev3 (single fan, heatpipe) Singles and can share some thoughts:

Ixtrema IXP-64-14G (1600rpm, 42cfm, 14dba)
Ixtrema IXP-64-14R (1600rpm, 42cfm, 14dba)
Silenx Effizio EFX-09-15 (1600rpm, 42cfm, 15dba)
Antec TriCool High (2200rpm, 38cfm, 27dba)
Silenx Effizio EFX-09-12 (1300rpm, 32cfm, 12dba)
Vantec Stealth (1750rpm, 28cfm, 20dba)
Antec TriCool Med (1600rpm, 28cfm, 21dba)
Antec TriCool Low (1200rpm, 21cfm, 15dba)
Evercool EGF-9 (1200rpm, 24cfm, 16dba)

If your ambient isn't too high (say, 75F or lower) I've had good luck with the EFX-09-15; it is very quiet and moves a decent amount of air. Not as much as the stock fans (contrary to its specs), but it might be sufficient depending on your ambient temperature. I'll be replacing most/all of my stock fans with these.

The slower/quieter EFX-09-12 doesn't have quite enough airflow to keep the Singles from throttling.

My 2 Ixtrema's don't like being in a horizontal orientation and start to make clicking noises. I'm not sure it is just my 2 particular samples, or if this is a common failing of this model. Otherwise they seem as if they might be a good alternative.

The TriCool is interesting because you can set it to 3 different speeds ('low' is too low; 'medium' might be ok, but there are better fan options on this list at this performance level; 'high' is louder than stock).

The Evercool doesn't have sufficient airflow (even less than the EFX-09-12).

The Vantec Stealth is relatively loud compared to the rest of these but still quieter than the stock fan; it moves more air than the EFX-09-15 contrary to the specs so it may be another reasonable alternative.

I haven't been able to source the Noiseblocker BlackSilent Pro in in my neck of the woods.

Man all you guys moaning about the noise these things make... damn. I decided to make a video just for you:

https://vimeo.com/41028028

I accidentally set the thing down on something that was sticking up, and it got caught in the fan and broke the blades off. So I decided to give it some real cooling. Grin

That was my thinking. Heat pipes are great when you need to move the heat output to a different location so a larger fan will fit. But their heat pipe design doesn't move the heat any more than a large heat sink would.

I thought that too at first, but upon closer investigation the improvement is clear, they have increased cooling capacity.

I have highlighted the VRM area in Yellow, this area needs airflow to cool down. On the original revision they could not use a bigger heatsink as it would have blocked the airflow to this area, but with the heatpipe they were able to add an additional heatsink and keeping the VRM area cooled.

It's a Delta TSB series fan from an old server power supply. Probably about 5K RPM.

I can't remember what CPU it was,but that thing worked like a charm.I do remember the CPU never got over 50c @ about a 25% OC.But god was it LOUD!!!!!! Cheesy
