You'll need to wait until some other people get their Avalons so they can work on developing a solution

For example, Stan distortion

did a cooling block for the Lancelot FPGA board as part of a devcoin project a few months ago, the details of that are here: https://github.com/stan-distortion/qcool-monoblock

Try motivating him by placing a pre-order ;-)

Please Avalon, don't be like BFL; if there is some delay in manufacturing/assembly, then please let us all know. It is obvious something is going on and I, as a potential customer, don't like being lied to (that was my biggest beef with BFL.)

It is a little fishy that even some Batch 1 customers THAT ARE IN CHINA have not received their ASICs yet...  

Still no tracking number received.

I hope I get it before I find a notice on my door one day saying that DHL came by and no one was home, or worse, they leave the notice on my neighbor's door and I never know.

dou you think we can immerse the modules ìn mineral oil?

Hello ngzhang, nice to see your comments about device cooling.
Im planning to use my own custom-made openframe aluminium case for 4gpu and install hashing modules there, probably would be using already installed motherboard, compile device specific cgminer and just connect it via usb (or reuse native avalon controller, but then fan control logic needs to be overwritten).
Fans probably would be right on the heatsinks of modules.
What do you think, is this better than just using your case design as-is?
PS. still no track no.

I can use less noisy fan or even put the radiator outside?

I mean putting the radiator with fans outside recirculating oil with a submersible pump. It's cold here most of the year. Thanks for your input.

Regarding this what about installing fans that go faster or are of lower voltage and produce more RPM..

Regarding install of extra fans. Could you install extra devices to this that do not use the PSU inside the Avalon, but actually use a separate customized modual that you install them to the Avalon unit in places to add extra air flow intake and airflow out???

Regarding PSU over heat... What about using own PSU that is higher graded  PSU and is better controlled for air flow and heat.

Regarding water cooling: Yes, do it...... Can you advise on what cooling would be good for this??? How would you actually fit a block big enough I know about engineering so I could make a custom plate to fit on to all the chips. Where would you actually need to install water cooling to this unit what chips if all or some need to be covered??

I understand the modules have the big blocks on them already are they just sat on top of the chips or are they fitted to them securely and dimensions cut out for them

I believe what he is saying is that installing extra fans at the back to push out the air will starve some of the airflow through the PSU causing it to overheat. The PSU sucks air from inside the case so setting up the classic push-pull configuration is not necessarily better.

I'm confused. Don't these units come all ready working with fans installed and all that?
