if you collect enough condensation points, you get to bonus round.

Forget condensation, I would be worried about food poisoning and food going bad because the cables cause a leak in the air vacuum in his fridge ...

although I'd assume the foot to store elsewhere, the board is a bit more costly than some cheese and butter - maybe you store caviar in your fridge, I don't. 

I'd be more interested in good and very quiet cooling-solutions as these compact and easy to cool boards (compared to GPUs) could also be mounted in usual living-/work- and bedrooms. How much sound do you have with the standard-cooler, e.g. is it less than the fridge?

Won't happen.

Condensation happens when warm air meets a cold surface.
But in the fridge, air is cold and the FPGA is warm.

Anyone ordering some of the new quad boards in the UK? (PM me.)

What about creating a group order for us Europeans?

If we reach 50+ units price becomes interesting IMHO.

I think Chefnet is already doing a group buy in .de. Check the German forum.

It seems to me, I don't speak german, they're doing a group order of single-fpga cards.

I think we could make a pan-european group order for quad-fpga cards, written in english.

20x 1.15x running very stable now. Thanks for that great product.

Here is my setup if anyone is interested:

They changed from singles to quads, with some exclusions. The count of ordered quads is ~35 at the moment. Maybe Chefnet will add a few English details to the thread on request.

That's hideous.

It's about as clean as you can get without making your own custom USB cables.

Interested in the EU Group, but i cant understand german , so i 'd rather an english group ( in this forum will be great....so no need of new registering issues)

Those USB cables can be a pain when you have a large cluster.  Those standoffs are a nice touch.  How high are they?  Do you notice any speed/heat issues with the bottom boards?

But in the fridge, air is cold and the FPGA is warm.

So it'll only happen directly above the FPGAs?

If you write Chefnet in English he will understand you. So where is the problem? He's already at a good amount of units and this makes the price even better. If you need some post translated and google translator or other tools are not good enough, point e.g. me to it and I gonna tell you what it says.

No.

This is so beautiful . Can you tell me where you got this spacer thingies you used to stack the singles?

[BR0KK]

U can get them in every good hardware supplier. I got mine from a local store in Freiburg.

Awwww I want to have 15 more of these units. I only could afford 5 ATM

Regardless of opinion on practical application of thermal dynamics, all the thinking available will not make it any smarter to place expensive electronics into a refrigerator and I would be rather certain in that doing that would instantly void any kind of warranty request for when, not if, the board stops working from whatever the next hair brained idea comes along. Seeing that picture was like seeing someone kick a puppy. That poor FPGA needs a good home. Please, stop the abuse.

Actually I don't see anything dangerous here. Condensation could possibly bite you when removing it from the fridge, but only if it wasn't mining immediately before it gets removed from it. Condensation isn't likely to happen at all here.

I consider it a valid approach at evaluating the thermal behavior of that board.

My God how many stupid things you read in this forum, the board just spent 20 minutes in the fridge for a test. Neither the food has been contaminated, nor was there any kind of condensation, because as someone said condensation can not be created on a hot surface.
It was just a test by someone on the forum if it seemed a good idea to put your FPGAs in a gas cooling system is very cheap as a refrigerator.
But from now on I will keep these tests for myself so I will not have to put up with absurd criticism.

[Turbor]

Chill out I had to laugh when I read about the test. I like to hear what others do to improve performance.
