What is the rated current for powering Fans? i.e. what's the largest Amp rating fan I can put on the board? 1amp?
I assume there are 2 fan headers on the board of the Habanero to power 2 fans? (+ another one for pump)

I am tossing up between these 2 fans:

Sunon 120mmx25mm PMD1212PTB1-A(2).F.GN-3pin fan

Rated Current: 1.0 Amp

or

Sanyo San Ace 120mm 109R1212H1011, 120x38mm-3pin TAC Sensor, Hi-speed 2600RPM, 102.5cfm

Rated Current: 0.52 Amp

Planning on sticking the fans on a Corsair H100i or H105. Any idea on the difference between these 2 model Corsairs?

Also considering going BIG.. and getting the Corsair H110 with 140mm fans, but i can't seem to find 140mm server fans on ebay.

Cheers,

Absolutely agree with ya on those points

Yes, you are of course correct. My mistake.
But there are many changes at the chip and hardware level, so I wouldn't expect flawless operation of a full linux image. And between optimizations for the A8 and floating point implementation, I expect an image built for the banana will far out-perform an r-pi image running on the banana.

BTW, I started my career 30 years ago with bare metal and it's still my favorite. Too bad there's not much work in that field anymore. The current philosophy seems to be to "if it has more than a few lines of code, slap an OS on it". This over-complication of the trivial reduces embedded system reliability IMO.

Here is a quick screen shot of running at 300Mhz, and if you look at the right side you can see Asic2 (green) when I turned the screw a bit on that part of the cooling head that the temp dropped down. 

Just an example of what I was talking about above

Anyone who ordered more than one board or did more than one order in our system, we will be grouping the boards into one box and sending them out.

Few things since we have been quite busy this last week.

Orders will be going out this week to customers, you should receive a shipping tracking number when your order is processed and we are doing our best to get them all in boxes and out the door this week

So I have been personally testing boards with a h80i clone, basically I took the ones out of a sierra and used that, but its more than just a clone since it has a san ace 120 12v super spicy fan on it that really blows though a lot of air the radiator.  I dont think the stock fans on the H products are enough esp if you want to push these boards.

I have probably put on and tested several boards now this cooler and my plan of attack is to get the cooling head on to where you start to feel tension in the screws, then start up cgminer at a 300Mhz rate and fire up the Pepper tool which reads cgminers api and displays a visual graph of the 4 die temps.  I try to align them as close as possible together by tightening the section of the die thats hot and seeing if I can visually see the temp go down.  Once I have them close to all the same temp, then I restart cgminer at 550, try again, then up to what ever speed im shooting for.  Note, I hope to release this tool this week, its still in its early phases but for this functionality it works pretty well and I hope to have some time in the next day or so to write up a blog post on it.

Awesome! Nothing here yet.

All my power gear is on the way. I suppose I should decide on something to cool with tomorrow.

Arm is a backward compatible CPU architecture. It is supposed to be able to run any compiled code for any previous version of arm

So bearing that in mind the bananapi(arm7a) should be able to run the raspi(arm6) image


Source: arm.com and some searching
            Personal experience bare metal coding small apps for arm MCU and MPU

Just received a ship notification (for tomorrow) for my first card.  Second order still processing.

Good job on turning these around, can't wait to get them going.

MrTeal,
you have PM from me about my order please can you have a look at it

I have some universal GPU water blocks, twin radiator and 600L/h pump from my old PC which I'm planing to use so any overclocking would not be possible most likely.
I hate LINUX, it's like going back to stone age Still remember MS-DOS

Most of the websites claim the same raspbian works on both systems, however i haven´t tried it.

They also claim it is compatible to Raspberry Pi images.

They run fine under cgminer in Windows, though at least for the time being some of the extra tools (like voltage tweaks) will require linux.

Would there be any Win7 program for these boards ?
I have Rpi but hate it to the bone.

The R-pi is an ARM11 processor (armv6 arch.) and the banana-pi is an ARM cortex A8 processor (armv7a arch).
They are not code compatible.
You can run a linux image on the banana-pi especially created for it, then build cgminer or bfgminer for the arm7a which I have done for my pcDuinos.
However there is no version of Minepeon available that I am aware of, which is unfortunate as I like the web interface that comes with Minepeon. Saves time not having to always ssh into them.

I considered that side hack solution but prefer to stick to 1 PSU per board.

I have 3 stable, 1 old AMC and 2 new ones.
CPU is at full load, but only clocked to the mild overclock (i think 600, no overvolting)
I haven´t got any original HF boards, but i thought firmware was similar?

You can clock your rPi to ~800 with a bit of overvolting, so it shouldn´t be a problem for 5.

Alternatively you could buy a bananaPi with around 4 times the cpu and 1 GB memory for 60$. OS should be compatible, haven´t tried though.

Collider,

Do you really have 5-10 Hashfast devices stable on a single pi? If so can you confirm details such as board rev, and what version of CGMiner you are using. I have a handful of pi's that I intended to use on rev 1 boards but could never get them to work. I was able to run that many chilis on a single pi but never the Hashfast boards.

5-10 devices easily.
Just buy as many as you want to and get a second pi if it isn´t enough.

With more than 10 devices in one room, cooling should be a bigger problem than buying a second Pi.

If you build a bigger rig with these, custom water cooling might be a good solution.

On the RasPi note .... any idea how many Habanero's a single RasPi can support before one exceeds the RasPi's ability to keep up?  On another note I've found the most recent HF RasPi MinePeon image quite stable.  Does anyone know if that same image will play nice with the Habanero cards?

H@shKraker

If were a betting man, I would put money on the rPi as your most likely point of failure. Maybe they will play nicer with Habaneros than BJs or Sierras.
