ngzhang do you plan to improve the current design or it will stay like this until next gen chips are available?

there is a update version under development. but the release date is still a secret.
the primary targets are add some useful functions and lower the cost. "maybe" the speed will significantly improve during  april. if so, the update can use for both icarus and future designs.

I wonder if this is going to work with Raspberry Pi  ARM device... it would be very nice.

 Grin hope there are some open-sourced guy will do the job.

Some temporary cooling. I am just wondering how I best blow on the boards for effective cooling. At an angle with the legs on one side longer (as in the second picture) or straight (last image).

They are 220-240V fans with a power consumption of around 15W each. I used every last one of my power sockets. And it's just temporary.



Hey, antirack, are those 80mm fans or 90mm? (the look like 80 to me). I'm looking to do something similar and I'm not sure what type of fans I want to use. I am thinking either 3 120mm thermaltake USB powered fans or 3 80 to 120mm 110-120V AC fans.

The 3 I have are 120mm 220-240V (not the most power efficient solution but it's just for a while).

What do you think is a more power efficient solution? How many watts does each fan consume?

I'm thinking of using these:

they are in testing.

every board needs a 100+ hours burn-in test before shipment.  Grin

the big fan usually turned off, on purpose to let the boards working at a high temperature.

ngzhang, what's the (room) temperature near the boards with the big fan turned off when you run all of them at the same time? And what is the room temperature?

15W each. No idea how others would do. I went to shops and bought the first ones I saw Grin
I also saw 12V or 24V, but I didn't want to buy a ATX PSU and start fiddling with tools.

... and just to reply here so others know for sure if they were wondering Smiley
Yep the Chinese plug pack that comes with the boards is 100% OK to run in Aus/NZ directly on 240V 50Hz with a plug adapter.

I had a bunch of software problems that I sorted out and one question I asked ngzhang was if the Plug Pack would be OK
(since I had no idea what was causing mine to not work)
He said yes and I can also confirm it is OK since it is all now working as expected with the original plug pack with a local adapter
- which was also made in China Smiley

the room temperature is 24 C

the (room) temperature near the boards with the big fan turned off is 26 C

I've been doing some digging on ebay and apparently 120-220V fans aren't all that cheap. So one possibly solution is to power normal 12VDC case fans with wall-wart power adapters. The advantage of that approach is that the 12V case fans consume far less power. Granted if one is going to do this without using a standard PC power supply there will be some wire cutting/splicing involved.

If anyone knows where to find some cheap 120V AC fans please share the info. By cheap I mean below $20 (which seems to be the average price for some of the more decent units)

I've just been using 120mm 12V case fans that came with Molex connectors already attached. These were only about $4 at my handy local computer super mall (Pantip Plaza). But I'm sure there must be the same on eBay too. I think these ones use about 0.6A - so 7 Watts.

I've been thinking a bit since I made my previous post, and I've decided to go the same route - ie to use regular 12V case fans. The question that I have for you folks is what kind of airflow is recommended (as in CFM rating) for these fans? I intend to use 120mm fans. I've been thinking of getting some el cheapo 52 CFM (3 in total stacked on top of eachother). The second option is to go for a 85 CFM one (this one: http://www.newegg.ca/Product/Product.aspx?Item=N82E16835130018&nm_mc=OTC-sho6b0tCA&cm_mmc=OTC-sho6b0tCA-_-Case+Fans-_-CoolMax-_-35130018) It's a bit louder and I do not necessarily need the blue LED lighting, but it's one of the cheapest high'ish CFM fan that I've found on local online retailers.

There is a FAN2 socket on the Icarus board and it's 12V.

Would it be possible to use this for a 12cm fan without extra power supply?

yes and please use a fan less than 0.2A

I'm running my Icarus with 12 V from my powers supply. I had to chop the original plug. Now my question. I'd like to connect Icarus to my second 13.5 V PSU. Is that ok or are 13.5 V too far out of specs for the boards ? The ZTEX have no problems but he clearly states up to 16 V. Without go from Zhang i'm not going to burn it up !

This is definitely the cleanest solution then, I will look for those and small plugs that fit the board.

It should, at least if you use MPBM as your mining software. Not sure about the other softwares.

the optimize voltage range is 10-14V. and 14.5V absolute.

Ok thanks for the info. I'm happy with the board so far !
