Confirming 4 units here in Romania. I finally came in their possession today. All four of them are hashing away and work fine so far.

No Kidding! It was a nightmare to put it on.

I'm thinking to move everything outside of the box, just like an open GPU mining rig, and use an external blow fan to effectively cool all those huge heat sinks when summer arrived
Do not do that.You need a air pressure + flow inside the box in order to cool down the ASICS
 
I have to agree.

The whole thing seems to be very well designed. The positive air pressure does its job even without running at full tilt.

I don't think Mods are really necessary. What might be interesting is someone making a third party water or liquid cooling system. Though honestly, without being able to take it past 300mhz....I don't really see the point.

At 300mhz mines fluctuates between 29C and 34C and the fans rarely ever speed up. The hashing rate changes wildly between 80GH/s and 66GH/s. Perhaps it is doing some kind of internal rate adjustment?

I also agree with Ngzhang and Bitsyncom about raising the price. These devices if used properly can make back it's cost in less than 2 days at current BTC prices.

If you do Solo mining...perhaps even shorter than that as Jeff Garzik seems to be a pretty lucky guy at that.

You know what's not well designed..the mechanism for holding the top case cover on.

The case need air pressure because the PSU currently do not get enough airflow, that's also the reason they don't recommend you to install a exhaust fan since it further decreases air pressure for the PSU, but if PSU can get cold air when it is seperated from other components, it will be much more healthy

For the cooling of ASICs, I think a 200mm turbo blow fan will provide much more airflow then those 120MM fans

Anyone know how to fix the avalon fan speed at a constant rate? I think current variable fan speed control sometimes cause cgminer to restart

I have a controlled environment with free power and a dedicated portable cooler, in addition to the building cooling... with high speed redundant internet, in Washington DC, with a brand new platinum 1200 watt PSU.  I'm not interested in making huge profits, but I am interested in setting an example for a long term deployment.  =)  Hopefully the price won't be so high on batch 3 that I'm excluded from the good ole boys club.  =)  I hope there is a way that I could give at least one of these things a good home.  =)   I am a hardware guy, helped build out one of the original data centers here on the east coast.  worked in a few others for a short time.  Sat next to a massive PDU and chiller in a secure basement facility near the NRO for a few years... damn , please don't let me see any pictures like that again... it just hurts me inside a little bit...

After a few calls to DHL i managed to get hold of my tracking number.

The packade has been pciked up in Hong Kong , planned for delivery Friday if all goes well with customs.

My order number is 2xx417.



Yes!!!!!

I finally managed to get my device from DHL after ALOT of phonecalls.

It's up and running.

Country:Sweden
Ordernumber 2xxxx417.

Got mine early in the morning.

#5x4 (USA)

FINALLY good for you dude!

At 35 Out temp will be about 65-70 or something which will shorten PSU live.

this is true.  I believe its wise to power them with the best quality PSU we can find.

Or to move psu outside Smiley

Ugly but i will see if the psu cable length will allow it. And to mount some aluminum on the big hole left when psu is not there so that we can keep the air pressure in the box

Дорогой товарищ Vicus,

We are discussing technology here not a profit right?

No matter what you do and how big your profit is you shall know how changes you make to your environment affect unit itself. And you have to think in a first place about it.
And do not worry to much about me i will take care of my units putting there my knowledge and efforts. So they will  feel good which will make me feel good also

Think about yours when they come and how you will take care of them

The funny thing is that i am able to put mu units in -20 C environment but unfortunately they will blow. No jokes here.

And remember not all of us are here because of the profit alone there are other important things involved also!
Дорогой товарищ loshia,
Ты чо быкуешь? А если длинне, то:

ngzhang already said, that unit was tested under temp < 35C and was fine. Why are you searching problem, were it not exist?
What about my unit, I'll put it in data-center, with 20C constant temp, UPS+automated diesel generator...

Super! I am glad for you and wish you all the best. For the profit you are about to get it is a better idea to think about nuclear power reactor as backup - you have a lot of them in Russia, haven't you? ohh yea end they are cheap  Grin

Besides with diesel generator you have to check the petroleum level and there is a big chance that generator not to start up when you need it

What i was saying that in ambient 23 we are reaching almost 50 Celsius out and that Increasing fan speed does not make out temp to cool down.
At 35 Out temp will be about 65-70 or something which will shorten PSU live.

However i am not putting at any doubt in NG statements for sure. But better ambient will not heart anybody.

As you can see when Fans operating at full speed it does not affect temp out at all or it affects it very little. I am worried what will happen when my room temp reach 35 Celsius Huh

Hopefully it will happen after a couple of months  Wink
With such profit, you can install room air-conditioner and keep consistent temp whole year.

My setup is on the ground-floor and temperature there is always around 5-20 celsius. I also can place each unit in different room. I think I have some time to figure it out.

Top unit 1: 1680/1800 fans, 17/47 temperature
Top unit 2: 2040/2040 fans, 16/44 temperature
Bottom unit 1: 1800/1320 fans,  14/38 temperature
Bottom unit 2: 1680/1560 fans, 15/41 temperature

Guys, give me some numbers to compare. Wink

P.S. Ooops, Bitsyncom has just clarified the question while I am typing this post.

Same results here dude. Temp is ok.

Dude,
Leave some space in between each two- preferable. I used some of the "rubber thing" from the package. Cut it to four small pieces and put in on top of the first one, then put second one on top. There must be some air between each other



this is incorrect, units are designed to stack directly on top of each other without additional things in between.
OK...
Excuse me. That was what i was thinking. But you know better BitSyncom Smiley

Best

Maybe I am wrong but there are special holes/bolts at the top/bottom to stack two units. If you place something between, units holes/bolts will not be used. Am I wrong?

As I told before, the temperature is fine. I can't understand all these talks. The primary indicator is the temperature sensor, not our assumptions. Would you please share your data from the sensors? Here is mine:

Top unit 1: 1680/1800 fans, 17/47 temperature
Top unit 2: 2040/2040 fans, 16/44 temperature
Bottom unit 1: 1800/1320 fans,  14/38 temperature
Bottom unit 2: 1680/1560 fans, 15/41 temperature
