I have a question about SP30. As i read in the product information you will have a chip that can pump 300GH/s. How do you plan to cool it? Looking at your competition KnC has a chip that can do ~170 GH/s and they have a big ass radiator for every chip. HashFast has a chip that can pump 750GH/s and it is water cooled. Bitmine.ch has a chip that does ~25GH/s and they need a big ass radiator too. Your case for SP30 makes me think that you will have the same construction as SP10, but somehow it doesn't feel right. Could you please explain a bit?

The answer there would appear to be that they expect significantly greater power efficiency. Normally I would recommend extreme caution: Getting power estimates vastly off appears to be par for mining hardware companies but in this case they apparently have a first chip in operation.

I think they changed the description from the SP30 product. Now i see that their chip will do 187 GH/s at 0.38W/GH which translates to 71W per chip on a "23 mm x 23 mm HFCBGA with stiffener" area. How big is the KnC chip?(just to compare)

I wonder what was the estimate on their SP10 chip and if they got it correctly because every power estimate was off on every asic chip.
