If you got solidworks/inventor you could run analyst on cooling systems and identify flow and trap locations and adapt to low power solutions to dissipate heat.

Your post regarding an air cooler dissipating 350watt is nonsense. Dual 120mm radiators with decent fans of 1500-1800rpm would dissipate up to 300w. I am not sure where you're pulling your magical unicorn numbers from. Feel free to post a air cooler that can dissipate 350watts, make sure it doesn't have 5000rpm fans attached to it.
I just need to quote this to show you don't know what you're talking about and you're not worth arguing with.
I can't help but laugh and want to humor this guy with a pic of my air cooled habanero running at slightly better than baby jet speeds ~435 Ghs

why so many power connectors?
Why not, its just a test board and there's plenty of board space. For the retail boards you just don't dont drop PCI-E connectors through and leave them as empty connections.
I personally would have preferred the chips to be centralised and squashed together more so we could have used standardised PC heatsinks cooling all 4 chips. 350W can be done with one higher end air heatsink or basic 120mm watercooling. I think its time we moved away from these strange aluminium blocks with obscene fans to make up for the low surface areas.
With a price of a high end air cooler it would be easier to buy one of those corsair aio water cooling units and have better performance for a price in the same ballpark.
High end air with a sensible fan = will do that fine while being smaller, lighter and cheaper. Either way it doesn't matter because I don't think its what we're getting.
I'm not sure what high end cooler you are referring to. For $80-100 a H series Corsair AIO will dissipate more heat regardless.

I am assuming this is what you consider a high end air cooler, if that is the case then yes the Corsair units would be better all around.

That cooler master will be a huge awkward sized cooler where the corsair will be a small block with a radiator where you can position to your convenience...
... no, just no....

How loud of the fan?
In your webshop, you combine 2 miners into 1 units.
Not sure about fan sound when run in turbo mode.
I want to run it on an office or living room, do you have info on this?
on the power distribution board you have an option to attach fans to 5V when underclocked In your webshop, you combine 2 miners into 1 units.

Can I ask how many flashing LEDs it has? Need LEDs because they create extra hash

What is the power usage "at the wall" for turbo mode?

Awesome, as always, Martin is kicking ass and taking names in the bitcoin miner manufacturing game!

In comparison to the Hex16e4s, are these units larger or smaller?
Have you had any issues like you had with the HEX4M's or HEX4E's?
longer but thinner and shorter.Have you had any issues like you had with the HEX4M's or HEX4E's?
this prototype is 130x130x300 (including fans)
The issue with hex4m and hex16e was the batch of microchip PIC controllers.
