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.

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.

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

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:(

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.

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

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.

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://bitcointalksearch.org/topic/wait-list-bfl-singles-order-date-ship-date-77796

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).

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.

Yes, it uses a standard 120-240v AC/DC converter, so anything should work.

At the beginning they had some general questions about the product. What is it's purpose, how does it work and so on. Well, after a few minutes of explaining (unit to calculate hashes, bitcoin,...) they started to do their own research. Finally, after another 20 minutes they came back and started asking me again. They did not find any useful information Wink

After a proposal of one of the employees they agreed to declare it as additional computer parts. After nearly an hour of waiting they used the TARIC Code: '8473 3020 00 0'

So, you told them you going to 'mine' bitcoins, which is commercial use, and they still passed it as a non commercial item? I.e. for personal use?

Anyone from the EU (preferrably Germany) received their BFL single? I am concerned about customs here and the "CE" sign. Does BFL put a CE stikcer on their Single? That would help getting it thorugh customs, afaiH.

I received mine this week and had to pick it up at customs. After a longer discussion about the product itself, what it is supposed to do and especially how they could declare it, I only had to pay the VAT. There wasn't a check for the CE sign. Feel free to contact me if you have any other questions.

It would be interesting to know what HS code they used for the Singles. Could you elaborate a bit more on the discussion you had at customs?

In short - my estimated risk was higher than the actual for the boxes, so I changed my mind.

Thanks again for your honest answer, can I have one more question, please?

Are you going to wait more 12-15 weeks from now on, or the wait time for the singles will be transferred to the Mini Rigs? I am curious, whether they are going to use chips they have prepared for your singles in building Mini Rigs for you, or not.

Those chips in minirig are different from the singles' chips, so they can't be used in both systems.

Ok, since people are waiting on my order to get shipped, and see how long it'll take them I have to confess. I've changed my order to 2 mini rigs. Grin

.

I have to ask

Did BFL somehow convinced you to do so? Some earlier shipping times or something else than a good will?

Just curious, thanks.

After having more concrete information on mini rig boxes, and finding out that in terms of taxes its more convenient and cost effective to have mini rigs instead of so many separate singles. In short - my estimated risk was higher than the actual for the boxes, so I changed my mind. This choice benefits me, BFL, and those who ordered singles....and Inaba of course, since he's probably gonna win that bet Grin

... maybe not, there are so many orders that are not on the list right here. Sonny told me that only orders from Russia are around 30 units, excluding those 50 I had on order.
